In the present embodiment, the decoration object model is a model of a decoration object in a target space to be decorated. The home decoration object can be furniture such as a cabinet, a table and a chair, a sofa and the like, infrastructure such as a door and the like, or decorations such as wall paintings, potted plants and the like. In the embodiment of the application, for the home decoration object, a three-dimensional model of the home decoration object, that is, a decoration object model, may be constructed. The decoration object model can be placed at a proper position in the three-dimensional model of the target space so as to simulate the decoration effect of the corresponding decoration object in the target space.
In the embodiments of the present application, a specific implementation of building a three-dimensional model of a home decoration object is not limited. Alternatively, a three-dimensional model of the home decoration object, i.e., a virtual three-dimensional model, may be obtained as the decoration object model by a three-dimensional reconstruction technique such as automatic modeling. Alternatively, the home decoration object may be photographed by a panoramic camera to obtain complete panoramic data of the home decoration object. And in the later stage, a three-dimensional model of the home decoration object is obtained through three-dimensional reconstruction technologies such as automatic modeling and the like, and the panoramic data is mapped onto the three-dimensional model of the home decoration object to obtain a real three-dimensional model of the home decoration object as a decoration object model.
The target space to be decorated can be the physical space of a house, a venue, a factory workshop and the like to be decorated. In the embodiment of the application, a three-dimensional model of the target space, namely a decoration space model, can be constructed. For a specific embodiment of constructing the decoration space model of the target space, reference may be made to the above-mentioned related contents of constructing the decoration object model, and details are not described herein again.
In some application scenarios, for a user simulating decoration, the decoration object model needs to be rotated to view decoration effects at a certain angle, which requires providing the function of rotating the decoration object model. In the prior art, the decoration object model is generally rotated by taking a central point as a rotation center, but the rotation mode is poor in flexibility. The central point of the decoration object model is the geometric center of the decoration object model.
In some embodiments, for some home-mounted objects, it is not practical to rotate around the center point of the home-mounted object as the center of rotation. For example, in the case of a door, the door rotates around a door axis as a rotation axis in a real physical space. For the object model of the door, the center point of the door model is used as the rotation center for performing the center rotation, so that the door model cannot simulate the rotation of the real door. For example, in the case of furniture, a user wants to observe a decoration effect by rotating a furniture model around a certain line of the furniture model as a rotation axis, but the furniture model cannot satisfy the observation requirement of the user by rotating around a geometric center thereof as a rotation center.
In the embodiment of the present application, in order to improve the flexibility of rotating the decoration object model, in step 101, a central point of the decoration object model and a designated rotation axis set with the decoration object model as a reference may be obtained.
The designated rotation axis may be an actual rotation axis of the home decoration object corresponding to the decoration object model. For example, for a door model, the specified axis of rotation may be a left door axis or a right door axis of the door model, or the like. Alternatively, the specified rotation axis may be an axis set with the decoration object model as a reference. For example, for a model table, the designated axis of rotation may be a leg or side of the table, or any line on the table, etc. Of course, the specified rotation axis may or may not be located on the decoration object model. For example, for a door model, the designated axis of rotation may be the left door axis of the door model, and so on. For the mural model, the designated rotation axis may be any straight line on the mural model, or may be a straight line having a set distance from a certain straight line on the mural model, or the like. For example, a wall corner line 1 meter to the left of the mural model, etc.
In the embodiments of the present application, a specific embodiment of obtaining a specified rotation axis set with the decoration object model as a reference is not limited. In some embodiments, the rotation axis of the decoration object model may be set in advance; and stores the correspondence between the identification of the modified object model and the rotation axis. Accordingly, the rotation axis corresponding to the identification of the device object model can be acquired as the specified rotation axis based on the correspondence between the identification of the decoration object model and the rotation axis. In other embodiments, a graphical user interface may be provided with a pivot axis setting control through which a user may set a specified pivot axis. For the electronic equipment executing the virtual decoration method, responding to the operation of the rotating shaft setting control, and acquiring the rotating shaft set by the operation as a specified rotating shaft; and so on.
Wherein the designated rotation axis may be implemented in the form of description information described with the decoration object model as a reference. E.g. the left door spindle of the door, the right edge of the table, etc.
Of course, the embodiment of the present application also does not limit the specific implementation manner of obtaining the center point of the decoration object model. For an electronic device that performs a virtual decoration method, a correlation between an identification of a decoration object model and a central point may be set in advance. Accordingly, the center point of the decoration object model may be acquired based on the correspondence between the identification of the decoration object model and the center point. Alternatively, the center point of the decoration object model may be acquired from a device that constructs the decoration object model. The equipment for constructing the decoration object model can automatically acquire the central point of the model in the process of constructing the model.
Since the center point of the decoration object model and the designated rotation axis are provided with the decoration object model as a reference, in step 102, the relative positional relationship between the designated rotation axis and the center point of the decoration object model can be determined. Alternatively, the relative positional relationship between the specified rotation axis and the center point of the decoration object model may be determined based on the center point of the decoration object model and the relative positional relationship of the specified rotation axis in the decoration object model.
Specifically, the size description information of the decoration object model can be acquired. The size of the decoration object model and the size of the actual decoration object can be reduced in equal proportion according to a certain scale. For example, the scale of the decoration object model to the actual decoration object is 1: the height is 2.4m, the width is 1.6m, the thickness is 5cm, and the corresponding dimension description information of the decoration object model can be as follows: height of 2.4cm, width of 1.6cm, thickness of 0.05cm, etc. Of course, in the embodiment of the present invention, the actual size of the decoration object may also be used as the size description information of the model, or the size description information of each decoration object model may be represented by any other available information representing the real-time size of the model in the model, which is not limited in the embodiment of the present invention. For example, in consideration of the fact that the three-dimensional model of the target space may be scaled, the real-time size of the decoration object model relative to the three-dimensional model of the target space may be used as the size description information when the decoration object model is displayed in the three-dimensional model of the target space.
Further, the relative position relationship between the center point of the decoration object model and the specified rotation axis in the decoration object model can be determined according to the size description information of the decoration object model. Further, a relative positional relationship of the center point of the decoration object model and the specified rotation axis in the decoration object model may be determined, in order to determine the relative positional relationship between the specified rotation axis and the center point. The relative position relation between the rotating shaft and the center point of the decoration object model is specified, and the center point of the decoration object model can be used as a reference object for description. The distance information in the relative position relation described by taking the central point of the decoration object model as a reference object is the distance information presented in the decoration space model, and the distance information has a certain scale with the real distance of the real world. For example, specifying the relative positional relationship between the axis of rotation and the center point of the decoration object model can be described as: the specified axis of rotation is 1cm to the left of the center point of the decoration object model, and so on. Wherein, 1cm is the distance displayed in the decoration space model, and has a certain scale with the real distance of the real world.
For the door model, assuming that the rotation axis is designated as the left door axis of the door model, the dimension description information of the door model is: the height is 2.4cm, the width is 1.6cm, and the thickness is 0.05cm. Accordingly, according to the size description information of the decoration object model, the relative position relationship of the central point of the door model and the specified rotation axis in the decoration object model can be determined as follows: the rotation axis is specified at 0.8cm left from the center point of the decoration object model, and so on.
After the relative position relationship between the designated rotation axis and the center point of the decoration object model is determined, in step 103, the position information of the designated rotation axis in the set coordinate system can be determined according to the position information and the relative position relationship of the center point in the set coordinate system.
In the embodiment of the present application, the set coordinate system may be any coordinate system. Alternatively, the set coordinate system may be a coordinate system established in a decoration space model corresponding to the target space to be decorated, such as a world coordinate system. Accordingly, a world coordinate system may be established in the decoration space model as the set coordinate system.
Furthermore, the center point of the decoration object model can be projected into the set coordinate system, and the position information of the center point in the set coordinate system is obtained. Optionally, for the world coordinate system established in the decoration space model, the central point of the decoration object model may be projected onto the corresponding position of the world coordinate system according to the setting position of the decoration object model in actual decoration, so as to obtain the position information of the central point in the world coordinate system.
Further, the position information of the designated rotating shaft in the set coordinate system can be determined according to the position information of the central point in the set coordinate system and the relative position relationship between the designated rotating shaft and the central point. The positional information of the designated rotation axis in the set coordinate system can be described in an intersecting manner. For example, the z-axis and the like can be represented by two planes of x =0, y = 0.
Since the decoration object model performs center rotation around the rotation center, the rotation center of the decoration object model before adjustment can be the center point of the decoration object model, and therefore, if the decoration object model is to be rotated around the specified rotation axis, the rotation center of the decoration object model needs to be adjusted to be on the straight line of the specified rotation axis. Thus, the decoration object model can rotate around the appointed rotation axis only when rotating around the adjusted rotation center. Based on this, in the embodiment of the present application, in order to achieve the effect of performing the axial rotation of the decoration object model around the specified rotation axis, in step 104, the rotation center of the decoration object model may be adjusted according to the position information of the specified rotation axis in the set coordinate system and the position information of the center point in the set coordinate system.
In the embodiment of the present application, a specific embodiment of adjusting the rotation center of the decoration object is not limited. Alternatively, a translation (translate) method in geometry may be employed to adjust the rotation center of the decoration object model according to the position information of the specified rotation axis in the set coordinate system and the position information of the center point in the set coordinate system. Specifically, the translation scale of the rotation center of the decoration object model may be determined based on the position information of the specified rotation axis in the set coordinate system and the position information of the center point in the set coordinate system. The translation scale of the rotation center of the decoration object model can be vector information. For example, the translation vector may represent a translation scale of a center of rotation of the decoration object model, or the like.
Alternatively, as shown in fig. 2, the vertical plane S of the specified rotation axis L may be determined in the set coordinate system according to the position information of the specified rotation axis L in the set coordinate system. The vertical plane of the designated rotation axis refers to a plane perpendicular to the designated rotation axis. Further, the projection position information of the designated rotation axis L and the center point a on the vertical plane may be determined based on the position information of the designated rotation axis in the set coordinate system and the position information of the center point a of the decoration object model in the set coordinate system, respectively. Shown as points L1 and A1, respectively, in fig. 2. Further, the translation scale of the rotation center of the decoration object model on the vertical plane can be determined according to the projection position information L1 and A1 of the designated rotation axis L and the center point a on the vertical plane, respectively.
Regarding the designated rotation axis L shown in fig. 2, the positional information of the center point a of the decoration object model in the set coordinate system is assumed to be (x 0, y0, z 0), and the designated rotation axis L is parallel to the y axis of the set coordinate system. Accordingly, the vertical plane of the rotation axis L is designated as the vertical plane S of the y-axis, i.e., the plane denoted by y = 0. Further, it is determined that the projection position information L1 of the specified rotation axis L on the vertical plane S is (x 1, z 1); the projection position information A1 of the center point a on the vertical plane S is (x 0, z 0). Further, the translation scale of the rotation center of the decoration object model on the vertical plane can be determined to be (x 0-x1, z0-z 1). Fig. 2 is an exemplary illustration only of the designated rotation axis being parallel to the y-axis of the set coordinate system, but is not limited thereto.
After determining the translation scale of the center of rotation of the decoration object model, the center of rotation of the decoration object model may be adjusted according to the translation scale. The center of rotation of the decoration object model before adjustment can be the center point of the decoration object model.
Specifically, the rotation center before the decoration object model is adjusted may be translated by the translation scale to obtain the adjusted rotation center.
For the embodiment of determining the translation scale of the rotation center of the decoration object model on the vertical plane, the translation scale can be translated on the vertical plane according to the projection position information of the rotation center before adjustment on the vertical plane to obtain the translated projection position information; and determines any one of target points (defined as a first target point) on a target straight line passing through the target position and perpendicular to the vertical plane S as an adjusted rotation center. The target position is a position corresponding to the translated projection position information, and the first target point is any point on the target straight line. In the embodiment of the present application, the first target point may be any point of the target straight line on the line segment in the decoration space model, or the first target point may be any point of the target straight line on the line segment of the decoration object model.
For example, in the case shown in fig. 2, the projection position information (x 0, z 0) on the vertical plane S of the rotation center (x 0, y0, z 0) before adjustment may be translated by the translation scale (x 0-x1, z0-z 1) on the vertical plane to obtain the projection position information (x 1, z 1) after translation. Correspondingly, the target position is a position L1 corresponding to the translated projection position information (x 1, z 1); the target straight line is a straight line passing through the target position L1, i.e., a straight line on which the specified rotation axis L is located. Further, it is determined that any point on the straight line on which the designated rotation axis L is located is the adjusted rotation center (x 1, yn, z 1).
In other embodiments, the foot of the central point on the designated rotating shaft can be determined in the set coordinate system according to the position information of the designated rotating shaft in the set coordinate system and the position information of the central point in the set coordinate system; and determining a translation vector from the central point to the plumb foot according to the position information of the plumb foot in the set coordinate system and the position information of the central point in the set coordinate system. And then, adjusting the rotation center of the decoration object model according to the translation vector from the central point to the foot. Specifically, the rotation center before the decoration object model is adjusted may be moved by the translation vector to obtain the adjusted rotation center.
The embodiment of adjusting the rotation center of the decoration object model shown in the above embodiment is merely an example and is not limited thereto.
After the adjusted rotation center is determined, the decoration object model may be rotated according to the adjusted rotation center in step 105, so that the decoration object model is rotated around the designated rotation axis in the decoration space model.
In the present embodiment, for an embodiment in which the specified rotation axis is located at the decoration object model, in order to rotate the decoration object model around the specified rotation axis in the decoration space model, the decoration object model may be rotated around the adjusted rotation center in the target rotation direction with respect to any target point (defined as a second target point) on the decoration object model except for the specified rotation axis. Wherein the target rotation direction is a rotation direction in which a rotation trajectory plane of the second target point can be made perpendicular to the specified rotation axis. The rotation trajectory plane of the second target point refers to a plane formed by a trajectory of the second target point rotating around the adjusted rotation center. Since the target rotation direction is a rotation direction in which the rotation trajectory plane of the second target point is perpendicular to the specified rotation axis, and the adjusted rotation center is located on the specified rotation axis, the decoration object model can be rotated around the adjusted rotation center in the target rotation direction, and the decoration object model can be rotated around the specified rotation axis.
For example, for the decoration object model shown in fig. 2, the target rotation direction for any point M on the decoration object model except for the specified rotation axis L1 is: the rotation direction of the rotation locus plane of the point M perpendicular to the predetermined rotation axis, that is, the rotation direction around the predetermined rotation axis L1 axis can be set. Further, the decoration object model may be rotated around the adjusted rotation center O1 (x 1, yn, z 1) in the target rotation direction. Since the adjusted rotation center O1 (x 1, yn, z 1) is located on the designated rotation axis L1, and the target rotation direction is: the trajectory plane can be rotated in the direction perpendicular to the specified rotation axis L1 at any point M on the decoration object model except the specified rotation axis L1, and therefore, for the decoration object model, the decoration object model is rotated around the adjusted rotation center O1 (x 1, yn, z 1) in the target rotation direction, and the effect of rotating the decoration object model around the specified rotation axis L1 can be achieved.
In this embodiment, the decoration object model can rotate around the rotation center through the decoration object model, so that the decoration object model can rotate around the designated rotation axis, the flexible adjustment of the rotation axis of the decoration object model is realized, the flexibility of the setting of the rotation axis in the virtual decoration is improved, and the experience of a user on the virtual decoration is improved.

For example, the execution subject of steps 101 and 102 may be device a; for another example, the execution subject of step 101 may be device a, and the execution subject of step 102 may be device B; and so on.
