JP 2007-025614 A JP 2007-257551 A JP 2011-018368 A Japanese Patent Laid-Open No. 9-106413 (Japanese Patent No. 3337355) JP 2000-111321 A

  By the way, visualizing a building so that it can be viewed from diagonally above or diagonally below, and displaying the interior corners of the building so as to have a depth is a place where 3D (three-dimensional) diagrams are good. By displaying so as to have depth, the positions and dimensions of windows, doors, furniture, fixtures, etc. do not become accurate positions and scales.

  In other words, 3D (three-dimensional) drawings are often used as advertisements for customers and as materials for explaining the internal structure, and drawings (plan views with dimension lines, etc.) for installers are created separately. It is customary.

However, in the known 3D drawings described in Patent Documents 1 to 5, after the building is completed, the customer's recognition and actual dimensions are different, and internal structures such as columns, beams, braces, etc. In the case of the presence or absence of objects, the customer's perception differs from the actual dimensions, and the customer's perception differs from the actual dimensions in the location information such as reinforcement members, lighting, water pipes, electrical wiring, etc. There were cases, and these differences in recognition sometimes caused trouble.
And it is complicated to create customer drawings and installer drawings and manage them individually. Also, some time after the completion of the building, when renovating or installing an air conditioner on the wall, the position of pillars, beams, bracing, etc., the position of lighting, and the position of the outlet cannot be confirmed Troubles can also occur. Also, on the construction side, there may be a difference in recognition between designers and installers (carpenters, electrical workers, renovators, etc.), and the presence and location of internal structures at the location where lighting is installed or renovated. There may be discrepancies in recognition due to relationships. Further, the customer may want to know whether the progress of actual building construction is progressing in conformity with the design drawing or 3D drawing.

  On the other hand, known 3D drawings are appealing in sales and transactions with a sense of realism and realism as drawings for building advertisement based on the contents of requests from customers. In addition, it can be used from the side of the actual building (including the contractor, designer, architectural model designer, CG producer, etc.), and is actually standing on the construction site. Need to create a new sense (a sense that the customer is actually standing in the 3D diagram), and that it is useful for field work (check the internal structure of the building, And confirming the position of the electrical wiring, etc.) will be necessary in the future. The numerical values / letters / symbols / graphics information necessary for the contractor, but the numerical values / characters / symbols / graphics information unnecessary for the customer, or conversely, the customer wants to know, but the contractor May have unnecessary numerical / character / symbol / graphic information.

However, when a 3D diagram is displayed by a computer, the computer needs a large amount of memory, and at the same time, a large load is applied to the computer. In addition, if all numeric values, characters, symbols, and graphic information are displayed, the vertical, horizontal, and diagonal numeric values, characters, symbols, and graphic information are mixed and overlapped, making it difficult to recognize the display. Furthermore, for example, in the case of a walk-through, there are many numerical values, characters, symbols, and graphic information, which hinders recognition. Also, if the start of the walk-through is always at the entrance, it takes time to arrive at the room you want to see, and it is difficult to see the numerical values, letters, symbols, and graphic information you want to see, and more memory is required. In addition, the power consumption of the computer is wasted.
Here, Patent Document 4 states that “a walkthrough is temporarily interrupted by a predetermined input operation that a cross-sectional structure such as a roof, a ceiling, a wall, or a floor is desired during a walkthrough as a moving image. However, if all the perspective cross-sectional views are prepared, a large amount of image data is required, and the walk-through operation is slowed accordingly. There are computer problems such as In addition, when the method described in Patent Document 4 is applied to 3D display, it is assumed that 2D numerical information such as a plan view or a developed view and 3D numerical information are displayed in an overlapping manner, making it difficult to recognize necessary information. There is a problem.
Furthermore, the numerical information, characters, symbols, and graphic information differ depending on customers, installers, designers, and the like. For example, customers may require numerical information, characters, symbols, and graphic information about internal structures such as columns, beams, bracing, piping, and wiring. Also, the walk-through route has different interests for each customer (e.g., women are more interested in the kitchen / dining room). If there is a place where there is a pipe in the case of a plumbing worker), a uniform route setting for the walkthrough, or a setting that is left to the operator, there is a problem that it takes time to go to the target place.

  Accordingly, an object of the present invention is to display only numerical value / character / symbol / graphic information desired to be obtained while performing a walk-through as a moving image, thereby preventing a problem that a memory capacity is insufficient and a computer operation is slowed down. CG architectural drawing display method capable of smooth walk-through operation by suppressing power consumption and displaying numerical values, characters, symbols, and graphic information in an easy-to-recognize manner without disturbing the walk-through, and The object is to provide a display program for CG architectural drawings.

  According to the CG architectural drawing display method of the present invention, a computer displays a building as a moving image based on image data subjected to computer graphics processing and performs a walk-through, and then displays a predetermined scene of the building as a still image. A method for displaying a CG architectural drawing, wherein when performing the walk-through, specific information such as numerical values, characters, symbols, figures, etc. in a predetermined area of the predetermined scene is not displayed, and a still image of the predetermined scene is displayed. When the operator selects one area of the predetermined area or a specific place in the area with the specific area selecting means, the specific information in the selected area is displayed.

  According to the present invention, when a computer displays a building as a moving image and performs a walk-through, specific information such as numerical values, characters, symbols, and figures in a predetermined area of a predetermined scene is not displayed, and the predetermined scene is stopped. When the operator selects one area of the predetermined area or a specific place in the area with the specific area selecting means when the image is displayed, the specific information in the selected area is displayed. Therefore, when performing the walk-through, only information suitable for moving image display can be displayed, the load on the computer, which is insufficient for memory and power consumption, can be reduced, and a smooth walk-through operation can be performed. The numerical value, character, symbol, and graphic information of the selected part can be displayed easily.

  The specific information is a numerical value, a character, a symbol, a figure or the like, and is a concept including a dimension line, an arrow, a sign, and the like. Then, numerical value / character / symbol / graphic information corresponding to the 3D diagram may be added to the 2D diagram such as a plan view or a developed view. In addition, equipment such as a washstand, a ventilation fan, a washing machine, a refrigerator, a lighting fixture, a clog box, a table, a desk, and a power panel corresponding to the 3D diagram may be added to the 2D diagram.

  As a specific method for the operator to select one area of the predetermined area or a specific place in the area with the specific area selecting unit, for example, the specific area selecting unit such as a mouse or a pointing device may be used. By selecting and inputting the two points, the distance between the two points is displayed. Further, for example, by designating and inputting one of the predetermined areas with a frame such as a circle or a quadrangle by a specific area selecting means such as a mouse or a pointing device, a predetermined area within the specified area is selected. The distance between two points is displayed. When the walk-through is performed on the 3D diagram, it is easier to see the numerical values, characters, symbols, and graphic information on the 2D diagram are not displayed.

  The present invention displays in advance a selection button for selecting each selection / designated place such as an entrance, a kitchen, a living room, a bedroom, a bathroom, etc., and is preset when an operator selects one of the selection buttons. In addition, the computer selects a route to be moved to the selected designated place from the walk-through moving routes, and performs the walk-through.

  According to the present invention, when the operator selects one of the selection buttons for selecting each designated designated place such as the entrance, the kitchen, the living room, the bedroom, and the bathroom, The computer selects the route to move to the selected designated location from the computer, performs the walk-through, and stops the walk-through at the selected designated location, so that a predetermined area of the building is selected from the walk-through stopped position. The information is selected by means, and the numerical value / character / symbol / graphic information in the selection range is displayed in an easily recognizable manner. A plurality of positions can be set as the stop position for stopping the walk-through. For example, a plurality of positions suitable for displaying the entrance may be set in advance. The walkthrough can be displayed in an easy-to-read manner by displaying only information such as numerical values suitable for 3D display. Other three-dimensional information and two-dimensional information may be sequentially displayed as necessary.

  According to the present invention, since the walkthrough is started from the selected designated location according to the predetermined movement route of the walkthrough, the walkthrough can be smoothly performed from the location of interest of the customer or the location of interest of the installer or the designer. Then, the numerical value / character / symbol / graphic information of the place where the user wants to know the numerical value / character / symbol / graphic information of a predetermined part of the building can be displayed. For example, for customers interested in dining, instead of starting a walk-through from the entrance, start a walk-through from the kitchen (dining), circulate around a predetermined part of the dining, stop, and When the specific area is selected by the specific area selecting means, the numerical value / character / symbol / graphic information of the predetermined area of the building in the selected range is displayed. As a result, the load on the memory shortage and power consumption of the computer can be reduced, and a smooth walk-through operation can be performed. From the stop position, a predetermined area of the building is selected by the specific area selecting means, and numerical value / character / symbol / graphic information of the predetermined area of the building in the selected range is displayed.

  The present invention is a display method in which a computer displays a three-dimensional visualization technique based on two-dimensional image data such as a plan view or a development view of the building, and displays a predetermined scene of the building as a still image.

  According to the present invention, the numerical value / character / symbol / graphic information of a predetermined location of the building at a position where a sense of depth such as a corner portion of each room of the building is displayed by CG or a position where the whole building perspective view is displayed by CG The numerical value / character / symbol / graphic information related to the CG display of the sense of depth, such as the corner of each room, rather than the numerical value / character / symbol / graphic information related to the floor plan and development of the building. It is preferable to provide priority display means for displaying with priority. According to the present invention, the numerical value / character / symbol / graphic information related to the CG display of the sense of depth of each corner of the room, etc., rather than the numerical value / character / symbol / graphic information related to the floor plan or development of the building. Priority is given to display values that are suitable for 3D CG display (only information such as values that are suitable for 3D display is displayed), thus preventing overlapping of numerical values, characters, symbols, and graphic information. Thus, the addition of memory and power consumption can be reduced. In addition, it is also possible to give priority to numerical value / character / symbol / graphic information related to a plan view and a development view of the building. The numerical information of the two-dimensional information and the three-dimensional information is sequentially displayed within the range selected by the specific area selection unit as necessary.

You may make it display.

  Next, the work procedure in the present embodiment will be described below with reference to the flowchart shown in FIG.

As shown in FIG. 5, first, a plan view of a building is read from the 2D figure information storage means 52 and displayed on the display 71 (reference S1), and basic information to be added such as floor plan information is input by the input means 10. (Code S2) Data processing is performed as two-dimensional information by the 2D diagram information processing means D2, and predefined processing is performed by the conversion processing means D21, and numerical information is automatically calculated (code S3). A three-dimensional diagram is displayed on the display 72 by the image processing means D1 (reference S4), and internal information such as the inside of the wall, the inside of the ceiling, and the inside of the floor is also displayed. Numerical / character / symbol / graphic information processing means D3 displays length / height information (position from the floor) from an arbitrary location in order to display numerical / character / symbol / graphic information N on the 3D diagram. use. Instead of the plan view, a 3D view can be created from the developed view. The information DB corresponding to this is retrieved and reflected on the 3D diagram for display. Thereby, numerical values, characters, symbols, and graphic information (actual dimensions) of locations corresponding to the 3D diagram are displayed (FIGS. 1A and 1B, etc.). In FIG. 1, the actual size of the space between the opening formed on one side of the staircase and the space between the openings (room layout) is shown. On the computer screen, when the two points (start point and end point) of the point to be measured are pointed by the input means 10 (reference S5), the vector calculation processing means D5 performs vector calculation processing between the two pointed points and automatically displays the distance. (Reference S6). In addition, in a state where the person stands out from the left and right at the position (viewpoint position) C1 where the virtual person stands, the display range of the 3D view can be changed by changing the angle range θ (FIG. 1A )).
On the other hand, when the viewpoint information processing means D6 determines the information of the viewpoint position C1 on the plan view (reference S7), the position in the 3D view is adjusted accordingly. Here, the display is performed assuming that the person has spread his / her hands to the left and right at the position (viewpoint position) C1 where the virtual person stands (direction in which the virtual person looks). Accordingly, the position of the 3D view is adjusted correspondingly.
Next, these pieces of information are combined (reference S8) and displayed on one screen (reference S9). The 3D view and the plan view are combined and laid out and printed from the printing means 15 such as a printer or plotter (reference S10). As a layout, as shown in FIGS. 6A, 6B, and 7C, FIGS. 7A and 7B, this is used as a layout for one business pamphlet, advertisement 1A, 1B, 1C, or the like. it can. As a layout method, plan view information is taken into a predetermined site or room space, and a 3D diagram in which numerical values, characters, symbols, and graphic information are input is created in correspondence with the plan view information.

The coordinate information processing means D4 converts the coordinate information provided from the 2D information processing creation means D2 and the numerical value / character / symbol / graphic information processing means D3 into a 3D diagram. For example, as shown in FIGS. 3 (a) and 3 (b), the coordinate information processing means D4 calculates the numerical value of the corresponding part of the 3D image from the dimension of the column E1 and the dimension of the window frame, and the numerical value / character / symbol / It is displayed on the 3D screen via the graphic information means D5. The vector calculation processing means D5 is used when displaying the numerical values, characters, symbols, and graphic information such as the length, width, size, and position of the internal structures E1 to E4 such as columns, beams, and braces. The internal structure display means D8 is used when displaying the internal structures E1 to E4 such as columns, beams, braces, and the like.
The viewpoint information processing means D6 is used when displaying the direction of the line of sight, the display angle, and the display range on the 3D diagram at the viewpoint position (a position where a virtual person stands and sees) C1. Further, the viewpoint information processing means D6 adjusts the viewpoint position C1 input on the plan view so that the display direction of the 3D view is a direction / angle corresponding to the viewpoint information C1.
The hierarchical display means D7 displays the internal structures E1 to E4 such as pillars, beams, braces, etc. hierarchically in 3D, and displays either one of them or superimposes them simultaneously. As the hierarchical processing means D7, it is also possible to display the change in the brightness of the illumination spot by the lighting fixture (downlight or the like) indicated by the symbol W in FIGS.

  Fig.1 (a) is a top view centering on the entrance of a building. The viewpoint C1 shown in FIG. 1A and its left and right direction lines C2 (C2 is a line indicating a state where a person standing at the viewpoint position C1 has spread his hands left and right, and the center of the left and right lines C2). FIG. 1B is a 3D view of FIG. The numerical value / character / symbol / graphic information N indicates the actual location and a line from the measurement location (a line drawn from the left and right ends of the measurement location) of a predetermined location of the staircase or an opening provided on the wall of the staircase. In an architectural model, a scale size and a marked size can be given. At the same time, a plan view can be added and displayed, or a partially enlarged view can be added (see FIGS. 1A and 1B). The numerical value / character / symbol / graphic information N can be drawn and displayed at an arbitrary position. Further, in the system according to the present embodiment, as shown in FIG. 2A, numerical values, characters, symbols, and graphic information can be displayed so as to be raised.

The walk-through display according to the present embodiment sets a virtual viewpoint for image data relating to a building planned to be built by the user in advance, and whether the user moves the viewpoint by operating the input means 10 such as a mouse. By stopping, the building is displayed as a moving image or a still image on the screen, and a visual effect similar to that of walking around the building can be obtained on the screen. At this time, in accordance with the movement of the viewpoint, the arithmetic processing unit performs real-time calculation on the image data, and the moving image can be displayed by calculation data that changes every moment. The walk-through control includes movement speed, stop J2 / movement resumption (start) J1s, reversal of the movement direction, or warp movement to the target location described above.
In the input means 10, the operator inputs a movement point to set a movement route that the observer (operator) plans to observe, and also to a specific position (for example, “living room”, “ Specify a room name such as “dining (kitchen)” or “Japanese-style room”. In this way, the room name representing the specific position and the data of the movement point designated by the movement route display are also supplied to the two-dimensional information storage unit 52 described above, and the corresponding coordinate data is supplied to the movement point coordinate information storage means 54. Accumulated.

  The walk-through display of the present embodiment inputs a route (moving route) to walk through image data (numerical values, characters, symbols, and graphic information) related to a plan view and a development view of the building to the computer 8. On the 3D display corresponding to, walk-through display is performed according to the walk-through information. For example, a walk-through according to the route of the electrical wiring Dr, the route Hr of water supply / drainage, the route of ventilation Ar, the position of the lighting fixture, or the like. In the case of the electrical wiring Dr, by displaying the wiring Dr in the ceiling portion and the wiring Dr in the underfloor portion, it is possible to confirm the continuity of the outlets and distribution boards in the room and the wiring in the ceiling portion and the underfloor (FIG. 9A). b)). When the ceiling part or the floor part is displayed, the priority display means D18 may display the numerical value / character / symbol / graphic information N as the three-dimensional information in preference to the two-dimensional display. For example, if you can see a part of a pillar but the other part of its length is hidden behind a wall, ceiling, or floor, and you want to know its total length, open the ceiling or floor and adjust its length. It is possible to measure, measure the length of the portion of the column covered with the wall, or display the length of a predetermined portion of the column inside the wall (see FIGS. 8B and 8C). At this time, the priority display means D18 displays the numerical information N and the like to be displayed in a state suitable for the display at a portion having a sense of depth suitable for 3D display. This is, for example, a 3D diagram display corresponding to viewpoint position information and viewpoint direction information viewed by a virtual person.

  In the walk-through control, the movement point data stored in the coordinate information accumulating means 54 is obtained from a continuous viewpoint (observer) connecting the movement points from the coordinates of the discrete movement points. This is supplied to a viewpoint calculation unit that calculates a viewpoint that is a movement locus. As a calculation method performed by the viewpoint calculation unit, for example, a method of obtaining a line segment, a polyline, or a spline curve connecting these plurality of points based on a plurality of discrete points can be applied (FIG. 14).

  Here, using an electronic camera (route setting camera) that can take still images and videos, place the camera icon on the displayed image, and specify the camera insertion point and what the camera is looking at (target position) In the dialog box, you can specify the camera path and target path, set the number and rate of frames to use, and if you shoot a building or site and save it as a movie in this way, it will also walk Through route can be set. If you create a target path with line segments or polylines, you can switch not only the camera movement but also the camera viewpoint.

  According to the present embodiment, viewpoint position information and viewpoint direction information that a virtual person stands and inputs are input, and a 3D diagram corresponding to these viewpoint position information and viewpoint direction information is displayed. In addition, the numerical value, character, symbol, and graphic information of the predetermined part of the building can be displayed within a range that is easy to see on 3D corresponding to the viewpoint direction information.

  The operator of the computer 8 uses the input means 10 such as a mouse to move the walk-through point setting means D15 and the movement route with respect to the building floor plan displayed on the displays 71 and 72 in this way. Setting is performed by the route setting means D16 (FIG. 14). This route can be set on the electric wiring Dr etc. using the electric wiring Dr etc., and can be along the electric wiring Dr etc., but the movement point set in this way is the movement It is stored in the point coordinate storage unit 14 as discrete coordinate data representing each point. Based on the discrete coordinate data stored in the movement point coordinate storage unit 14, the viewpoint calculation unit calculates a viewpoint, which is a continuous viewpoint movement locus connecting the movement points. Considering the shape of the room in the building, the furniture that is virtually arranged, etc., and avoiding the obstacle that hinders the movement of the observer, the viewpoint as the movement path of the observer An operation is performed so that Further, in the present embodiment, the operator can easily view the information by preferentially displaying the three-dimensional information so that the two-dimensional numerical information and the three-dimensional numerical information are not overlapped.

As described above, the viewpoint data obtained by the viewpoint calculation unit is stored in the viewpoint data storage unit. The viewpoint data that is the movement trajectory of the continuous viewpoint (observer) stored in the viewpoint data storage unit is supplied to a rendering calculation unit (not shown) serving as a projection calculation unit that performs a projection calculation. In addition to the viewpoint data, the rendering operation unit exchanges data with 3D data from the 3D diagram information storage unit 51 and the like.
When the calculation processing in the rendering calculation unit is completed, a signal (information) indicating the end of the calculation is sent to the read control unit. Information for instructing to move (warp) instantaneously to a room or the like where the viewpoint is to be placed directly is transmitted to the read control unit. For example, the warp can be moved from the entrance J1 to the bedroom 1 (FIG. 1 (b), FIG. 3 (b)).

  FIGS. 9A and 9B and FIG. 10 are examples of displaying the lighting fixture J10 and its electrical wiring relationship. The lighting fixture J20 and its electrical wiring Dr are displayed on 3D based on the ventilation system device and wiring Dr drawn in two dimensions in advance in FIG. On the 3D display, the walk-through is performed along the electrical wiring Dr, but the two-dimensional walk-through moving route Dr is not displayed. By displaying only the electrical wiring Dr on the 3D display in FIGS. 9A and 9B, it is easier to imagine than the case where it is arranged on an actual floor or the like.

  According to the present embodiment, by walking through the route Dr of the electrical wiring system, the person in charge of electrical work can quickly move to a necessary construction place and the like, and the portion is enlarged and displayed at the place where electrical work is necessary.
