Description

201030673 VI. Description of the Invention: [Technical Field] The present invention relates to a display device, a display method, an information recording medium, and a program, which are suitable for being easily placed in an object disposed in a virtual space. Observe the details of the object you are paying attention to. [Prior Art] For example, in Patent Document 1, a technique is disclosed in which an object such as an enemy character, a bomb, or a trap placed in a virtual space is displayed on the face of the game, and these objects can be enlarged. Display and let the user observe. [Prior Art Document] (Patent Document) Patent Document 1: Japanese Laid-Open Patent Publication No. 2005-095347 [Draft of the Invention] * [Problems to be Solved by the Invention] However, only the object is enlarged and the back side of the object cannot be observed. Waiting for the situation. Therefore, it is strongly desired to present the appearance of an object not depicted on the face of the face to the user in an easy-to-view manner. The present invention is to solve such problems. The purpose is to provide a display device, a display method, an information recording medium, and a program, which are suitable for the object to be placed in the virtual space, so that the user can easily observe the details of the object noted by 201030673. [Technical means for solving the problem] = The above-described object is achieved. The display device according to the first aspect of the present invention includes a s recording unit, a display unit, a selection instruction receiving unit, a side receiving unit, and a rotating unit. The recording unit records the position of the object disposed in the virtual space = the position of the direction/point, and the position and orientation of the projection surface of the predetermined size: here, the virtual space, for example, refers to the game stage three times: Virtual space...object 'generally, refers to the role or back of the game recorded in the card". The information of the projection surface, typically the second and second series: see the point to produce a perspective projection on the projection surface to show the virtual space projected on the projection surface, and the end = two windows "" (4) In the touch panel and the like, t is selected by touching either one or the like. Also = enough to move by pointing the finger touching the touch panel toward the moving direction to specify the moving direction of the viewpoint. The selection instruction receiving unit accepts a selection instruction input indicating that the object to be included in the generated image: ‘: visible object is selected. Selecting the indication receiving portion, for example, detecting that the touch panel or the operation key is depressed to be the one of the displayed items that the user wants to select; the individual objects in the space can be regarded as visible object. Virtual 4 201030673 , accepts the direction specified input, which specifies the direction in the space where the viewpoint is to be moved. For example, it is detected that the user specifies input for the touch surface to accept a direction for specifying a direction to be configured in the virtual space.

The rotating part system pivots the viewpoint and the projection plane to the object arranged in the virtual space in a specified direction, centering on the selected visible object. The rotating portion is made to be viewed in such a manner that the virtual object is rotated in the visible object selected by the user to correspond to the specified direction, and the virtual space and the viewpoint are relatively lighted in the direction of the shirt. Rotate ground. That is, the virtual space itself is rotated around the visible object selected by the user, or the viewpoint and the projection surface are simultaneously arranged in two aspects. The other can be the center of gravity of the object, or

The direction designation receiving unit input is specified to be moved to the designated receiving unit, and the viewpoint to be moved by the borrowing plate or the operation key is moved around the visible object. The center of the outer object, such as the location where the user touches the object. Thus, according to the present invention, the user can observe the details of the object of interest from various angles. In order to achieve the above object, a display device according to another aspect of the present invention includes a recording unit, a display unit, a selection instruction receiving unit, a direction specifying receiving unit, and a rotating unit. The recording unit records the position and orientation of the object placed in the virtual space, the position of the viewpoint, and the position and orientation of the surface having the predetermined shape of the transparent field and the opaque field. The display unit is a line segment connecting the position of the object and the position of the viewpoint through an object of a transparent field (hereinafter referred to as a visible object) to be displayed at the intersection of the line segment 5 201030673 and the transparent region. The method of projecting the projected image is selected to receive βρ, which accepts a selection indication input indicating that any of the visible objects is selected. The U receiving unit is designated to accept the direction of the input, and the direction designation is the direction in which the viewpoint is to be moved in the virtual space. ^ The rotation system is centered on the selected object 4, and corresponds to the position and orientation of the object arranged in the virtual space. The surface of the predetermined shape in the fork corresponds to the projection surface and is disposed between the viewpoint and the virtual space. The display unit displays a portion projected on the transparent area while the virtual space is being viewed from the position of the viewpoint by the position of the viewpoint. That is, the transparent field is completed as a window for viewing virtual space.

The user's touch is selected by any one of the objects displayed on the touch panel or the like. Further, the user moves the finger or the like that is touched on the touch panel in the moving direction, and the movement of the specified viewpoint is rotated to make the viewpoint view by rotating the viewpoint. Centering on the selected object (eg, the center of gravity of the object, or the location at which the user touches the object, etc.), the position or orientation of the object being configured in the virtual space is rotated based on the specified direction. Further, as will be described later, it is possible to rotate all the objects in the virtual space, or to rotate a part (that is, a visible object). Thus, in accordance with the present invention, by taking the selected object as the deliberate, 6 201030673 based on the specified direction, the position of the object arranged in the virtual space is rotated in rotation 'to enable the user to come from various angles Observe the details of the object being noted. Further, in the display device, the rotating portion can be made such that the position and the object to be rotated are visible objects.

In other words, the rotating portion can not only rotate the object in the virtual space, but extract the visible object projected on the transparent field before the rotation, and rotate only the visible object. Thereby, the number of objects to be rotated can be reduced to reduce the calculation load. Further, in the display device, the rotating portion can also rotate the position and orientation of the object other than the visible object (hereinafter referred to as an invisible object), and the distance between the invisible object and the viewpoint is compared with the visible object and the viewpoint. The distance is shorter, and the line segment connecting the invisible object and the viewpoint passes through the transparent field, and the rotation is suspended. That is, according to the present invention, although the object arranged in the virtual (four) is rotated based on the specified direction centered on the selected object, but after the rotation, the item is not displayed before the rotation. The object, projected on the transparent field of the shape of the file, hides the visible object. Since the visible object is the item that the user wants to pay attention to, it is not desirable to hide the visible object. Therefore, in the case where the rotating portion is rotated based on the specified direction, among the objects projected on the transparent field, the distance between the invisible object and the viewpoint is shorter than the distance between the visible object and the viewpoint. In this case, the rotation is aborted. I have prevented the invisible objects from being hidden. 201030673 View objects. Therefore, even when the selected object is rotated, it is possible to prevent the object from being hidden. Further, the display device can further include a field specifying receiving unit for specifying the input field of the receiving area, and specifying the input in the field, and designating the transparent area and the opaque area on the surface of the predetermined shape. * That is, in the virtual space, as long as the portion that is desired to be noted can be specified, the user can also specify the bit Φ constituting the transparent field on the face of the predetermined shape. The position of the transparent field, for example, is typically input using a touch pen or a mouse to obtain a closed field, and a circle is added to specify. If a smaller designation is made for the field of the rotated display, the object that is currently being noticed becomes easier to discriminate. Further, by obtaining the area to be rotated and displayed in a narrow manner, it is possible to reduce the so-called three-dimensional dizziness (the user who views the screen on the t-plane of the 3D rotation or fierce movement 35 is temporarily uncomfortable. symptom). Moreover, the image can be generated by the position and the line segment connecting the position of the rotated object and the position of the viewpoint through the object of the transparent field, projected on the intersection of the line segment and the transparent field. And projecting the line segment to which the position of the previous object and the position of the viewpoint are rotated through the object of the opaque field, and projecting at the intersection of the line segment and the opaque field. In other words, the display unit can also generate an image, which is projected on a predetermined area of the moon area by the rotation of the object in the virtual space before the object is rotated; the rotation of the object is performed later. The space, the situation, and the image projected on the transparent field of the predetermined surface. 8 201030673 By this, for example, it is possible to correspond to the user's desire to slightly view the portion that is not being noticed. x, because the generated image only rotates the part that is paying attention, and the other eight, , and his enthalpy does not change the image, so the part that can be noticed is the φ && 4 β sequence The effect makes the note part easier to discriminate.

That is, the field designation receiving department allows the smaller field to be designated as a transparent field. In this case, it is possible to reduce the amount of calculation. Prevent the area of 3D stun and set it in advance. Further, when the field designation receiving unit is equal to or larger than the predetermined area, it is also possible to specify the input in the received transparent area. The user will be able to use the predetermined area ‘only for the visible object to enter ’, and

It is also possible to receive the field-specific input when the number of visible objects exceeds a predetermined number. ° That is, the field designation receiving unit, in the case where the user specifies the transparent field in a manner that the number of visible objects is less than the predetermined number, receives the field finger 1 thereby, and the area for the transparent field is In the case of the limitation, in the case where only the visible object is rotated, the amount of calculation can be reduced. In addition, a method for predicting an area for preventing 3D stun can also be provided with a display unit including a direction specifying receiving unit and a display unit, and a display unit and a display unit for selecting another aspect of the present invention. The display method 9 201030673 instructing the display unit of the receiving unit and the rotating unit to select the instruction receiving step, the * designating receiving step, and the rotating step in the recording unit. Position and orientation, the position of the viewpoint has recorded the position and orientation of the object arranged in the virtual space. , 卩 and the position of the projection surface of the predetermined size In the display step, the raw perspective 浐-... is not displayed. p ' is a method in which the viewpoint 'generates a perspective W on the projection surface, and the object ^ is selected to receive the selection indication input, and the selection 指示 selects the indication receiving unit, and accepts the selected object. (The following ^5 people's refers to 7" to select any one of the generated images (hereinafter referred to as visible objects). In the direction-designated receiving step, the direction specifies the receiving part, and the receiving direction is input. Specify the direction

曰疋 Input specifies the direction in the virtual space where you want to move the viewpoint. I In the rotating step, the rotating portion is centered on the selected visible object, and the viewpoint and the projection surface are relatively rotated in the specified direction with respect to the object arranged in the virtual space. The display method of the other aspect of the present invention includes a display method including a recording unit, a display unit, a publisher selection center receiving unit, a direction specifying receiving unit, and a rotating display device. , Select means not to receive the step, direction to specify the receiving step, and to rotate the step. The position and orientation of the object disposed in the virtual space, the position of the viewpoint, and the position and orientation of the face having the predetermined shape of the transparent field and the opaque field are recorded in the recorded portion. In the display step, the display portion is a line segment connecting the position of the object and the position of the viewpoint through an object of a transparent field (hereinafter referred to as a shadow formed on the visible object 10 201030673) to be in the line segment and Like it, show it. In the selection instruction receiving step, the instruction input 'this selection' means to input one of the meanings. Select the indication receiving part, accept the selection, and the instruction is to be selected by the visible object.

In the following description, the display device can be replaced with a suitable general computer or an element of the game device 15 201030673, and these embodiments are also included in the scope of the present invention. The display device 200 of the present embodiment includes a recording unit 2〇1, a display unit 202, a selection instruction unit 2〇3, a direction designation receiving unit 2〇4, and a rotation unit 205. And the field designation receiving unit 2〇6, etc. Here, the recording unit 201' records, for example, information about a three-dimensional virtual space that becomes a game dance station. In this virtual space, for example, as shown in FIG. The object is configured with an object (for example, 4〇1A, 4〇ib, 4〇ic, etc.), a viewpoint 4 1 〇 (ie, a camera) for viewing the virtual space, and a surface having a predetermined shape of the transparent field 420A and the opaque field 420B. 420 and so on.

The face 420 of the predetermined shape corresponds to the projection surface on which the virtual space is to be projected. Although in the present embodiment, it is constituted by a flat surface, the shape thereof is not limited thereto. A typical predetermined shaped face 42 is disposed between the view point 410 and an object (e.g., 4〇1A, 401B, 401C, etc.) within the virtual space. Further, the direction of the line of sight direction 415 passes through the center of the face 420 of a predetermined shape, and the orientation of the vector perpendicular to the face 420 of the predetermined shape becomes uniform. Further, the boundaries of the transparent region 420A and the opaque region 42〇b disposed on the surface 420 of the predetermined shape are identical, and can be designated by the user as will be described later. The shape, position and orientation of the object to be disposed in the virtual space, the position of the viewpoint, and the position and orientation of the face 42' of the predetermined shape are previously recorded in the R 〇 M 12a in the cassette 12. The processing control unit 16 201030673 ίο' reads these materials from the appropriate card g 12 and then records them in wram just wait. The rotating portion 205' corresponds to an instruction from the user to update the shape, position, orientation, and the like of the object. The processing control unit 1A, the connector 11, and the card H 12 operate in cooperation to function as the recording unit 2〇1. When the display unit 202' receives an input for the #defined transparent area by the field specifying receiving unit 206, which will be described later, an image having the same size as the surface 420 of the predetermined predetermined shape is generated. That is, among the generated images, a portion of the transparent region of the image of the virtual space projected on the transparent field of the surface 420 of the predetermined shape is drawn at a position corresponding to the transparent region of the surface 42G of the predetermined shape. Further, among the generated images, an image depicting a predetermined color (for example, black) for expressing darkness is generated at a position corresponding to a field other than the transparent field (opaque area). Then, the display unit 202 displays the generated image on the second display portion 19 (or the 'display portion 18'). That is, although the surface 420 of the predetermined shape is described as being equivalent to the projection surface, in the embodiment of the present embodiment, the actual function as the projection surface is the transparent field of each of the surfaces 420 of the predetermined shape. Further, it is also possible to set the entire surface 42 of the predetermined shape to be a transparent field. The processing control unit 1A and the second display unit 19 (or the first display unit U)' cooperate to function as the display unit 2〇2. The selection finger receiving unit 203 receives a selection instruction input indicating that any one of the objects (hereinafter referred to as an object to be displayed) displayed by the display unit 2〇2 is selected. The user, for example, is contacted (touched) by 17 201030673, and the object to be selected is displayed on the touch surface & 2, and the object displayed by the display unit 202 can be selected. It is possible to perform the same operation as this (the operation key s is selected to select the object. The selected object to be received is temporarily recorded, for example, in the smashing, etc. The processing control unit 10, the operation key 17, and the touch panel μ The cooperative operation functions as the selection instruction receiving unit 2〇3. The direction designation receiving unit 204 receives a direction designation input from the user, and the direction designation input is specified in the virtual space to be in the virtual space. The direction in which the arranged viewpoint is moved. The user, for example, presses the operation key 17 corresponding to the predetermined direction, or can move the touch panel 2 while pressing it to specify the direction. The processing control unit 10, the operation keys 17, and the touch panel 2 are cooperatively operated to function as the direction designation receiving unit 204. The rotation unit 205 is connected by the selection instruction receiving unit 2〇3. The object is centered, and the object in the virtual space is rotated in such a manner as to be able to see that the viewpoint is moved in the direction received by the direction-designated receiving portion collapse, that is, reversed from the specified direction. In this manner, the position and orientation of the object placed in the virtual space are rotated, and the position and orientation of the object recorded in the record 201 are updated. The processing control unit 10 functions as the rotating unit 2〇5. The field designation receiving unit 206 is a receiving area specifying input 'the field receives input, and is on a surface of a predetermined shape, and specifies the transparent field and the opaque field. The user, for example, can acquire the closed field. 'On the touch panel 2G—to touch the pen under the house, move it to the line of the boundary of the field as 18 201030673 to specify the position and shape of the transparent field. Or, the user can also Perform the same operation as this (press the operation key 17) to specify the transparent field. The specified field to be received is temporarily recorded, for example The WRAM 1 〇d, etc. The processing control unit 1 〇, the operation keys 17 and the touch panel 20 cooperate to operate as the field designation receiving unit 206. The following is a description of the display device 200 according to the present embodiment. In the present embodiment, for example, a case where a game is executed is described as an example, and the game has a scene that must be searched for in the dark. In the game, the user is once When the transparent area is specified, the display is performed by the illumination of the flashlight only in the designated transparent area. Further, the user's selection of one of the items that are displayed in the transparent field is selected. And inputting to specify the direction in which the viewpoint is to be moved, the display device 200, based on the object, rotates the object in the virtual space based on the specified direction 'When, it will be used to display the rotated An image of the state of the virtual space is displayed in the field. The user seeks to find things by viewing the virtual space displayed in the transparent field specified by various angles. Further, in the present embodiment, the transition from the received input state of the user is shown in Fig. 5. In a state where nothing is received (state A) 'can receive the specification of the transparent field (state b) <·Next, 19 201030673 receives a selection instruction (state c) of the object that is rotated ten hearts, and then receives the viewpoint The specification of the movement direction (state D). Thus, under the object that is not selected to be the center of rotation, the indication of the direction of movement is not received; and if the area of the transparent area is not specified, the item that becomes the whirlwind is not received. In addition, in the states B, C, and D, a predetermined button can be input to release the designated transparent field (state E) (i.e., deleted by WRAM i〇d). In the state where the selection of the object is received, when the release of the transparent field has been designated (the transition of state C-E), since there is an object selected as the rotation_heart in the released domain, The selection of the object is also removed by the WRAM 10d deletion. In addition, the designated transparent area can be received in addition to the boundary portion of the drag field (the transition of the state B-B), and can receive the selection instruction of the object. Instructing, by selecting other objects in the specified transparent field (migration of state C-C) or after specifying the moving direction of the pilot, it is also possible to specify the moving direction (migration of state D-D). The display processing of FIG. 6 is a process in which the respective units of the display device 2A of the present embodiment operate in cooperation, and the processing is repeatedly performed at a predetermined timing as described above, and the display device 200 performs the response state corresponding to the transition. The display processing is described with reference to Fig. 6 . First, the state A is displayed, that is, when the user does not perform the initial state of designation of the transparent field and selection of the object. First, the 'processing control unit 10' determines whether or not it is useful to specify the input of the 20 201030673 moving direction of the viewpoint (step S101). That is, the wraM 10d or the like is referred to to judge whether or not the input is useful to specify the moving direction of the viewpoint. In the initial state, it is judged that there is no input for specifying the direction (step S1 〇 1; NO), and the processing proceeds to step S103. Next, the display unit 202 records the state of the virtual space projected on the transparent area in the frame memory (VRAM 10c) (step S103). That is, the display unit 202 refers to the recording unit 2 to obtain the position of the viewpoint, the position and orientation of the surface 420 of the predetermined shape, and the shape, position, and orientation of the object. Then, based on the acquired information, an image 'projected by projecting objects in the virtual space is generated on the face 42 of the predetermined shape. The image corresponding to the position in the transparent field (obtained with reference to WRAM 10d) is recorded in the frame memory (VRAM IOC) corresponding to the transparent field. However, in the initial state, since no transparency is specified. In the field, no image data is recorded in the frame memory. And continuing, the display unit 202 writes a material for displaying a predetermined color (for example, black) at a position corresponding to the opaque area of the frame memory (step S104). In the initial state, since there is only an opaque field, at this point in time, a black-faced image of the entire surface is recorded in the frame memory. The display unit 202 transmits the content of the frame memory to the first or second display unit (18, 19) at a predetermined timing (step, therefore, in the initial state, the first or The second display unit (1, 19) indicates a black-faced image. Then, the display processing is terminated. Next, the state B, that is, the user has designated the display processing of the transparent field 21 201030673, to explain The operation or the contact of the touch panel 20, input ° then, the field specifies the position and shape of the transparent field specified by the receiving portion, etc. The user performs the operation key 17 for specifying the transparent field 206, receiving By the input "and temporarily recorded in the WRAM 10d ' user, in the state where the transparent field has been designated, if the step si is performed, the processing control unit 10 determines that the specified party has not been rotated. Input (step No), and from step s103 to step s1〇5. As described above, step S1〇3 is performed to step s1〇5, and then among the displayed images, 'by the display unit 202 Virtual space It is projected to the position corresponding to the transparent field, and the other parts are displayed as black images, for example. 'FIG. 7A shows the state in which the virtual space shown in FIG. 4 is projected to the transparent field 420A. As shown in Fig. 7A, the object to be projected to the transparent field is the object 401A and a part of the object 4〇1b, and the others are projected to the opaque field. Therefore, as shown in Fig. 7B, the object 4〇1a The projected image 401A of the object 401A and the part of the object 4〇1b projected is displayed on the opaque field corresponding to the transparent region of the screen. The part is displayed as a spot color. Thus, the transparent area specified by the user is a part of the virtual space as if it is illuminated by a flashlight. As shown in Fig. 7B, in the present embodiment, each object is A point perspective method is used for perspective projection, while objects farther from the viewpoint are projected smaller, and objects closer to the viewpoint are projected larger. However, it is also possible to use parallel shots on 22 201030673 In addition, the display unit 202 uses, for each object, for example, a z-buffer method (in a three-dimensional drawing, an object or a face whose line of sight is blocked by a front object is hidden, and is not performed. The process of depicting green, that is, a method of eliminating hidden faces. Adding information about the depth of the color information of each element constituting the picture, and drawing the smashing of the picture with the same coordinates The depth information is compared, and only the object existing in the forefront is written into the kneading surface), etc., to perform the hldden surface eiimination to draw an image of the virtual space. Thus, because the display unit 202 is attached When each time a screen is generated, the image corresponding to the field of the transparent field on the face and the image corresponding to the field of the opaque field are drawn. Therefore, even when the user refers to the shape of the field to be changed, It can also reflect this change. Continuing, in the state where the transparent field has been selected, the user inputs the finger to select one of the objects to be represented, and then considers the input and the input to specify the moving direction of the viewpoint (state B - C - d migrate). That is, the 'user' touches the position of any item indicated in the field. The selection instruction receiving unit 203 specifies the object to be projected onto the field including the coordinate value at which the contact is made, and receives the specified object as the selected person (state c). For example, the selection instruction receiving unit 203 can also record the arrangement of the information for recording the object projected to the position corresponding to each pixel at the position where the object is projected, and record it in the WRAM 10d. In addition, it is also possible to sigh the face to 48〇><64〇 points (d〇t), and the arrangement is the arrangement of the dimensions of the 4th dimension, and when the object is represented, The information of the specific object (for example, object 1) will be stored on the corresponding pixel with 23 201030673; if it is not displayed, g will be stored on the corresponding pixel. Then, _d{ uses the information of the recorded object corresponding to the coordinate value of the w& and will be buried, and the object specified by the information extracted by δHai, the selected object is specified. " The sleek selection refers to the non-receiving unit 203, which is used for the purpose of specifying the selected object. In order to utilize the information of the object, it is temporarily recorded in the WRAM 10d. a In addition, of course, when the detected coordinates are not in the designated transparent area, 'the selection indication 胄2〇3' can also not receive the selection indication input. And the 'viewpoint's swaying side, example#, is The user touches the touch panel 20 while moving in a specified direction to specify. The movement of the contact is continuously detected by the direction specifying receiving 胄2〇4'. The direction specifying receiving portion 2G4 In the continuous (4) coordinate value, the coordinate value of the upper person is compared with the current coordinate value to calculate the distance and direction of the movement of the touch. When the moving distance is more than a predetermined distance, the square is The designated receiving unit 2〇4 receives the user's operation as a direction specifying input, and temporarily records the moving direction and distance in the WRAM 10d (state 〇). Alternatively, it can also be operated (depressed). The operation key 17 in the up, down, left, and right directions is used to specify the direction. In this case, the direction designation receiving unit 204 can calculate the viewpoint by the type of the depressed operation key 17 and the time of the depression. The direction of movement and the distance of movement. In this way, the user inputs an indication, which is selected by one of the displayed 24 201030673 objects, and further, I has performed the input state for specifying the direction of movement of the viewpoint. In step SUM, the processing control unit 10 determines that it is useful to input the movement direction of the specified viewpoint (step S1〇1; 疋). Then the processing proceeds to step S102. The continuous rotation unit 205 is composed of WRAM l〇d Obtaining the selected object ^ and centering on the object (for example, the center of gravity of the object, etc.), rotating the object arranged in the virtual space based on the direction of the being (Step S1〇2) The material is caused to rotate the object in the virtual space in the direction opposite to the designated direction to be accepted, only at the angle corresponding to the moving distance. [Standard ^ & Step S103 is carried out to the step Sl05 displays the image of the virtual two space on the transparent field projected on the surface 420 of the predetermined shape in the same manner as described above. For example, Fig. 8A shows that the transmission system is selected, and Μ 71n "object 8B in the field green" - Set the direction of movement of the viewpoint. As shown in the figure, the rotating portion 2G5 determines the axis 73G which is a vector 72 with the center of the object. And direction HO, two =: heart. The rotating portion I is rotated in the direction of the left axis of the axis (that is, the angle of the object is made in the first image to make the sleepy in the virtual space = turn. After being rotated, it is displayed on the screen. For example, 'in the recording unit 2〇j, the silk corresponding to the moving distance' and the prepared table (Uble) are defined by the (four) angle. The rotating unit (10) can also be determined by referring to the table 25 201030673: The rotation angle is such that the rotating portion 205 rotates the object in the virtual space, and the image displayed in the virtual space is displayed in the transparent field corresponding to the user. The field on the surface 'shifts the viewpoint in the direction specified by the user (see Figure 9). The user's system can also specify the direction of movement of the viewpoint and rotate the object (transition of state D) Alternatively, it is also possible to release the transparency/field entanglement (the state B, C, and D are moved to the state E). In this embodiment, a part of the virtual space is rotated and added. Way of observation When the finger in the transparent field is released, the virtual space is returned to the state before being rotated by the rotating unit 205. Therefore, the rotating unit 205 is virtual at the time before the rotation. The state in the space (the position and orientation of the object) is temporarily stored in WRAMlGd. Then, when the transparent area is released, the state of the temporarily stored virtual space is downloaded as the state of the current virtual space. When the 'transparent field is designated' object selection instruction and the direction of movement of the viewpoint is output by the user, the rotating unit 2〇5 starts the state of being downloaded, and rotates the object. In the present embodiment, the display device 2 is a virtual space in which the rotation of the object is performed, and the image of the transparent field portion that the user has projected on the surface 420 of the predetermined shape is displayed in correspondence. In the position of the transparent area on the screen. Therefore, according to the present embodiment, 26 20103 is placed in the virtual space. In the object, the user can easily observe the details of the object to be noticed. The above description has been made on the present embodiment, but the present invention is not limited to the above embodiment, and various changes and applications are possible. For example, in the above-described embodiment, all the objects placed in the virtual space are rotated around the designated object, and it is not necessary to do so. After the transparent field is specified, only the object that is projected on the transparent field (hereinafter referred to as the original visible object) is rotated in step S102 to be drawn on the transparent field. In this way, the object to be rotated is reduced, and the drawing process can be reduced. Further, the present invention is applicable to a case where a part of the game screen is displayed in detail in addition to a game for finding things in the dark. 0 For example, 'In order to investigate a part of the game that is displayed on the face of the game, the user circled the part to specify The field continues, once the object as the center of rotation is specified, and the direction of movement of the viewpoint, on the portion corresponding to the transparent field displayed on the screen, as described above, the display corresponds to the transparent field that has been projected in the specified The 'rotated object' is carried out in the specified direction. On the other hand, on the portion corresponding to the opaque field displayed on the face, the system can also display the state of the virtual space on the opaque field at the point in time when the field is designated. In order to achieve this, for example, the display unit generates an image in which the state of the virtual space is projected on the surface of the pre-shape when the field is designated (and before the rotation). Then, the display unit can also write the portion of the generated image that matches the opaque area to the position of the opaque field of the frame memory in step 27 201030673 : s:4. 10A is a description of the case where the user performs the input as shown in the first figure in the state where the virtual space shown in the Mth picture is projected and the image of the πth is displayed. That is, the user specifies the transparent field =, see the object that selects the object 4° 1A as the center of rotation, and specifies the direction Μ := Γ moving direction. As shown in the result of the TM image, it is revealed that the object is rotated by the object 41〇Α. = On the one hand, in the opaque field, the same image as the one displayed in the opaque field at the point of the designated transparent collar is displayed. The "" sample uses also show the part of the part that is not noticed at the same time, = can correspond to the user's request', that is, the user wants to view the part that is not in the mood. X ’ makes it possible to obtain an effect of causing the attention portion 4 to be reproduced only by moving the portion that is being noticed and the other portion is not changed, and making the attention portion easier to discriminate. Reasoning: The present invention can be used, for example, in a puzzle that wants to solve an event. The image displayed in the opaque field, 2 is an image of a live photo showing the current situation. In addition, in the transparent field, an image of the scene of the past that indicates the past situation is projected. In this way, "'s user specifies the location of the live photo (transparent field)', then the display shows that the past image near the scene is partially combined with the image on the current image, so that the performance is like For the effect of that part =:". The user's side considers what you want to pay attention to: where it should be, and you must test the reasoning ability by displaying the situation near the scene in the past by rotating it 28 201030673 to find the difference between the present and the past. This can create games that make users think more and use more minds. Further, in the above embodiment, the display unit does not limit the angle at which the object placed in the virtual space can be rotated. However, for example, when the display unit rotates the object in the virtual space based on the specified direction, there may be a short time after the designation of the transparent field (and before the rotation is performed), and the transparent area is not displayed. Any one of the objects (hereinafter referred to as the original invisible object) is disposed between the original visible object and the face of the predetermined shape. This result causes the original visible object to be hidden by the original invisible object. • Because the original visible object is the object that the user is paying attention to, it is not wanted to be hidden by the original invisible object. Therefore, the rotating portion firstly performs test rotation for all the articles. Then, when the viewpoint after the S-type rotation is connected to the original invisible object and the line segment passes through the transparent field (that is, when the original invisible object is projected to the transparent field), the next determination is made. That is, the length of each line segment connected to the original invisible object through the viewpoint of the transparent field after the rotation of the test is compared with the distance between the viewpoint and the original visible object to determine whether it is short. In the shorter case, either of the original invisible objects is located closer to the viewpoint than any of the original viewable objects, and there is a possibility that the original invisible object will hide the original visible object. Therefore, the rotating portion does not confirm the test rotation of all the objects, but returns the position and orientation of the object to the state before the start of the test rotation. Or, instead of returning to the state before the start of the test rotation, the distance between the viewpoint and the original invisible object is determined by the position of the viewpoint that is immediately shorter than the distance between the viewpoint and the original visible object. Rotate. On the other hand, if there is no shorter case, the rotating portion determines the test rotation. For example, the object arranged as shown in Fig. 11A will be described with respect to the moving direction of the viewpoint specified by the user, and the rotating portion is turned rightward around the stencil.

As shown in Fig. UA, the object 4〇lc is not projected on the transparent field 42〇a shortly after the designation of the transparent field 42〇a, and is the original invisible object. On the other hand, the objects 4〇18 and 4〇1B, immediately after the designation, are projected onto the transparent field 420A as the original visible object. In the case where the object shown in Fig. UB is obtained by the test rotation by the 11A, the original invisible object 4〇lc is moved to the position β projected to the opaque field 420B. In this state, the virtual space is When the condition is projected to the transparent field 420 of the surface 420 of the predetermined shape, an image as shown in Fig. 11C can be obtained. That is, the original invisible object 401 C hides a part of the image projected by the original visible object 401A. In order to prevent such a situation, the rotating portion compares the distance between the original invisible object and the viewpoint (e.g., distance 1012)' with the distance between the original visible object and the viewpoint (e.g., distance 1〇11). In Fig. 11B, since the distance 1〇12 is shorter than the distance 1〇11, the rotating portion is not determined for the test rotation and is suspended. Therefore, even if the object to be projected is not overlapped, it can be easily displayed without hiding the original visible object. 30 201030673 Further, it is also possible to limit the size which can be designated as the area of the transparent field in the face 420 of the predetermined shape. For example, when specifying a transparent area, the field designation receiving unit obtains the maximum width and the maximum length of the transparent area, and can be any one of the maximum width and the maximum length. Where the predetermined threshold value is recorded below, the field designation is not accepted. Thereby, for example, in a variation in which only the original visible object is rotated, it is possible to prevent the number of original visible objects from being excessive, and the amount of calculation regarding the rotation processing can be suppressed. Further, even when all the objects in the virtual space are rotated instead of rotating only the original visible object, the so-called 3D stun can be prevented by making the area of the rotated display small. Alternatively, in order to obtain the same effect, the field designation receiving unit does not receive the field designation when the number of original visual objects is equal to or greater than a predetermined threshold. Further, in the above-described embodiment, an image in which the object in the virtual space is rotated and the viewpoint has moved is displayed at a position corresponding to the transparent area of the screen. Otherwise, it is also possible to allow for the rotation. The position of the viewpoint itself (and the surface of the predetermined shape) is moved in the direction specified by the user, such as calculation accuracy. Alternatively, the 'rotation of the object and the movement of the viewpoint' can be performed simultaneously. Further, the present application is hereby incorporated by reference in its entirety in its entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire entire all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all [Industrial Applicability] 31 201030673 As described above, "in accordance with the present invention", it is possible to provide a display device, a display method, an information recording medium, and a program, which are suitable for use in an object disposed in a virtual space. The person can easily observe the details of the object of interest.
