Description

Technical Field

[0001] The present application relates to the technical field of graphic component design, and in particular to a composition acquisition method and device based on composition component modification. Background Art

[0002] Existing floor plan editing software pre-sets multiple graphic components. Most of the components are simple to place on the design drawing, such as sofas, tables, beds, and chairs. As long as the position, size, and orientation of the components are properly handled, the user's design needs can be met. In actual use, the simple placement of components can be achieved by setting preset properties such as the position, scale, and rotation of the components. However, for the placement of door components, in addition to the design requirements of position, size, and orientation, there may also be design requirements for the way the door opens. For example, the door component was originally designed to open on the left, and the door handle is set on the right side of the door.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] The process provided in the embodiment of the present application is applied to a floor plan editing system. Specifically, it can be executed by a server to modify the opening method of a door component and obtain a composition of a door component including different opening methods, thereby avoiding users from redesigning the door component.

[0049] like Figure 1 FIG. 1 is a schematic diagram of a composition acquisition method based on modification of a composition component provided in an embodiment of the present application, comprising the following steps:

[0050] S101: upon receiving a modification instruction triggered by a user for a door component of a left-opening door, obtaining a pre-built transformation matrix from a database.

[0051] The pre-constructed transformation matrix is ​​shown in formula (1).

[0052]

[0053] S102: Obtain the coordinates of each vertex in the door component of the left-opening door, and multiply the coordinates of each vertex in the door component of the left-opening door by the transformation matrix to obtain the coordinates of each new vertex, and construct the geometric framework of the door component of the right-opening door based on the coordinates of each new vertex.

[0054] In the floor plan editing system, the reference coordinate system of the door component is the right-hand coordinate system. Therefore, multiplying the coordinates of each vertex in the left-opening door component by the transformation matrix is ​​essentially to convert the X-axis coordinates of each vertex in the left-opening door component into negative values, while keeping the Y-axis and Z-axis coordinates unchanged, thereby obtaining the coordinates of each new vertex, and constructing the geometric framework of the right-opening door component based on the coordinates of each new vertex.

[0055] It should be noted that the specific implementation process of constructing the geometric framework of the door assembly of the right-opening door based on the coordinates of each new vertex is common knowledge familiar to those skilled in the art.

[0056] S103: Calculate the transposed matrix of the inverse matrix of the transformation matrix to obtain a normal matrix.

[0057] Among them, the transposed matrix of the inverse matrix of the transformation matrix shown in the above formula (1) is shown in formula (2).

[0058]

[0059] S104: Calculate the normal vectors of each face in the door assembly of the left-opening door according to the coordinates of each vertex in the door assembly of the left-opening door, and multiply the normal vectors of each face in the door assembly of the left-opening door by the normal matrix to obtain the normal vectors of each face in the door assembly of the right-opening door.

[0060] Among them, the specific implementation process of calculating the normal vectors of each face in the door assembly of the left-opening door based on the coordinates of each vertex in the door assembly of the left-opening door is common knowledge familiar to technical personnel in this field and will not be repeated here.

[0061] S105: Obtain the normal vector of each vertex in the door component of the left-opening door, and multiply the normal vector of each vertex in the door component of the left-opening door by the normal matrix to obtain the normal vector of each vertex in the door component of the right-opening door.

[0062] The normal vector of the vertex specifically refers to the normal vector of each face constituting the vertex in the geometric frame of the door component. In this embodiment, the normal vector of each vertex in the door component of the left-opening door is multiplied by the normal matrix. The specific implementation logic code can be:

[0063] for(varj=0,jl=face.vertexNorMals.length;j <jl;j++){

[0064] face.vertexNorMals[j]=nomalMatrix*face.vertexNorMals[j];

[0065] }

[0066] In the specific implementation logic code, face.vertexNorMals.length represents the number of normal vectors of the vertex, face.vertexNorMals[j] represents the normal vector of the vertex, and nomalMatrix represents the normal matrix.

[0067] S106: Setting the surface material and gloss of the door component of the right-opening door according to the normal vectors of each face of the door component of the right-opening door and the normal vectors of each vertex of the door component of the right-opening door.

[0068] In addition to the geometric frame, the door component also includes surface material and gloss. In the floor plan editing system, the normal vectors of each face and each vertex in the door component are converted by a preset formula to obtain the surface material and gloss of the door component.

[0069] S107: Displaying a door component of a right-opening door on the composition interface.

[0070] The composition interface may specifically be a graphic design interface of a floor plan editing system.

[0071] For details, see the following Figure 2 The door assembly shown consists of Figure 2 It can be seen that the surface material and gloss of the right-opening door assembly obtained through this embodiment are the same as those of the left-opening door assembly, and the only difference is the installation position of the door handle, that is, the door opening method is different.

[0072] S108: Based on the user's operation on the composition interface, generate a composition of the door component including the right-opening door.

[0073] Among them, users can use the composition of the door component of the right-opening door to achieve design requirements.

[0074] S109: Initialize the door assembly of the right-opening door, and store the door assembly of the right-opening door locally.

[0075] Specifically, initializing the door component of the right-opening door refers to recalculating the normal vectors of each face and each vertex of the door component of the right-opening door according to the coordinates of each vertex in the door component of the right-opening door. Storing the door component of the right-opening door locally can facilitate subsequent users to call the door component of the right-opening door.

[0076] In summary, when a user triggers a modification instruction for a door component that opens left, a preset transformation matrix is ​​called to transform the coordinates of each vertex in the door component that opens left to obtain the coordinates of the new vertex. Based on the coordinates of the new vertex, a geometric frame of the door component that opens right is constructed. The normal matrix is ​​called to transform the normal vectors of each face in the door component that opens left to obtain the normal vectors of each face of the door component that opens right. The normal matrix is ​​called to transform the normal vectors of each vertex in the door component that opens left to obtain the normal vectors of each vertex in the door component that opens right. The surface material and gloss of the door component that opens right are set based on the normal vectors of each face and the normal vectors of each vertex in the door component that opens right. The door component that opens right is displayed in the composition interface, and a composition including the door component that opens right is generated based on the user's operation in the composition interface. It can be seen that this embodiment can simply and effectively modify the door opening mode of the door component based on the modification instruction triggered by the user, obtain the composition of the door component including different door opening modes, and avoid the user from redesigning the door component.

[0077] It should be noted that in actual graphic design scenarios, some door components open upward, but as users demand for innovative designs, downward opening door opening methods have also emerged. To this end, this embodiment provides a composition acquisition method based on the modification of a composition component for the application scenario where a door component that opens upward is modified to a door component that opens downward.

[0078] like Figure 3 FIG. 1 is a schematic diagram of another composition acquisition method based on modification of a composition component provided in an embodiment of the present application, comprising the following steps:

[0079] S301: upon receiving a modification instruction triggered by a user for a door component of an upward-opening door, obtaining a pre-built transformation matrix from a database.

[0080] The pre-constructed transformation matrix is ​​shown in formula (3).

[0081]

[0082] S302: Obtain the coordinates of each vertex in the door component of the upper door, and multiply the coordinates of each vertex in the door component of the upper door by the transformation matrix to obtain the coordinates of each new vertex, and construct the geometric framework of the door component of the lower door based on the coordinates of each new vertex.

[0083] In the floor plan editing system, the reference coordinate system of the door assembly is the right-hand coordinate system. Therefore, multiplying the coordinates of each vertex in the upper-opening door assembly by the transformation matrix is ​​essentially to convert the Y-axis coordinates of each vertex in the upper-opening door assembly into negative values, while keeping the X-axis and Z-axis coordinates unchanged, thereby obtaining the coordinates of each new vertex, and constructing the geometric framework of the lower-opening door assembly based on the coordinates of each new vertex.

[0084] It should be noted that the specific implementation process of constructing the geometric framework of the door assembly of the bottom-opening door based on the coordinates of each new vertex is common knowledge familiar to those skilled in the art.

[0085] S303: Calculate the transposed matrix of the inverse matrix of the transformation matrix to obtain a normal matrix.

[0086] Among them, the transposed matrix of the inverse matrix of the transformation matrix shown in the above formula (3) is shown in formula (4).

[0087]

[0088] S304: Calculate the normal vector of each face in the door assembly of the upper opening door according to the coordinates of each vertex in the door assembly of the upper opening door, and multiply the normal vector of each face in the door assembly of the upper opening door by the normal matrix to obtain the normal vector of each face of the door assembly of the lower opening door.

[0089] Among them, the specific implementation process of calculating the normal vectors of each face in the door assembly of the upward opening door based on the coordinates of each vertex in the door assembly of the upward opening door is common knowledge familiar to technical personnel in this field and will not be repeated here.

[0090] S305: Obtain the normal vector of each vertex in the door component of the upward opening door, and multiply the normal vector of each vertex in the door component of the upward opening door by the normal matrix to obtain the normal vector of each vertex in the door component of the downward opening door.

[0091] S306: Setting the surface material and gloss of the door assembly of the downward-opening door according to the normal vectors of each face of the door assembly of the downward-opening door and the normal vectors of each vertex of the door assembly of the downward-opening door.

[0092] S307: Displaying the door component of the door being opened on the composition interface.

[0093] For details, see the following Figure 4 The door assembly shown consists of Figure 4 It can be seen that the surface material and gloss of the bottom-opening door assembly obtained through this embodiment are the same as those of the top-opening door assembly, and the only difference is the installation position of the door handle, that is, the door opening method is different.

[0094] S308: Based on the user's operation on the composition interface, generate a composition of the door assembly including the bottom-opening door.

[0095] Among them, users can use the composition of the door component of the bottom-opening door to achieve design requirements.

[0096] S309: Initialize the door assembly of the downward-opening door, and store the door assembly of the downward-opening door locally.

[0097] Specifically, initializing the door component of the bottom opening door refers to recalculating the normal vectors of each face and each vertex of the door component of the bottom opening door according to the coordinates of each vertex in the door component of the bottom opening door. Storing the door component of the bottom opening door locally can facilitate subsequent users to call the door component of the bottom opening door.

[0098] In summary, when a user triggers a modification instruction for a door assembly that opens upward, a preset transformation matrix is ​​called to transform the coordinates of each vertex in the door assembly that opens upward to obtain the coordinates of the new vertex. Based on the coordinates of the new vertex, a geometric frame of the door assembly that opens downward is constructed. The normal matrix is ​​called to transform the normal vectors of each face in the door assembly that opens upward to obtain the normal vectors of each face of the door assembly that opens downward. The normal matrix is ​​called to transform the normal vectors of each vertex in the door assembly that opens upward to obtain the normal vectors of each vertex in the door assembly that opens downward. The surface material and gloss of the door assembly that opens downward are set based on the normal vectors of each face and the normal vectors of each vertex of the door assembly that opens downward. The door assembly that opens downward is displayed in the composition interface, and a composition including the door assembly that opens downward is generated based on the user's operation in the composition interface. It can be seen that this embodiment can simply and effectively modify the door opening mode of the door assembly based on the modification instruction triggered by the user, obtain the composition including the door assembly with different door opening modes, and avoid the user from redesigning the door assembly.

[0099] It should be noted that the door assembly of the left-opening door is modified into the door assembly of the right-opening door. In addition, the embodiment of the present application can also modify the door assembly of the right-opening door into the door assembly of the left-opening door. To this end, the composition acquisition method based on the modification of the composition assembly provided in the above embodiment can be summarized as follows: Figure 5 Steps shown.

[0100] like Figure 5 As shown, another composition acquisition method based on composition component modification provided in an embodiment of the present application includes the following steps:

[0101] S501: upon receiving a modification instruction triggered by a user, obtaining coordinates of each vertex in the modified object.

[0102] The modified object is the first door component.

[0103] S502: calling a preset transformation matrix to transform the coordinates of each vertex in the first door component to obtain the coordinates of new vertices.

[0104] Optionally, the coordinates of each vertex in the first door component are multiplied by a preset transformation matrix to obtain the coordinates of the new vertex.

[0105] S503: Constructing the geometric framework of the second door component according to the coordinates of the new vertices.

[0106] The door opening methods of the second door assembly and the first door assembly are different from each other.

[0107] Optionally, the door opening method includes left-opening and right-opening.

[0108] Optionally, the door opening method includes upper door opening and lower door opening.

[0109] S504: calling a normal matrix to transform the normal vectors of each face in the first door component to obtain the normal vectors of each face of the second door component.

[0110] Among them, the normal matrix is ​​the transposed matrix of the inverse matrix of the transformation matrix.

[0111] Optionally, the normal vectors of each face in the first door component are calculated based on the coordinates of each vertex in the first door component, and the normal vectors of the faces in the first door component are multiplied by a normal matrix to obtain the normal vectors of each face of the second door component.

[0112] S505: calling a normal matrix to transform the normal vector of each vertex in the first door component to obtain the normal vector of each vertex of the second door component.

[0114] S506: Setting the surface material and gloss of the second door component according to the normal vectors of each face of the second door component and the normal vectors of each vertex of the second door component.

[0115] S507: Displaying the second door component on the composition interface.

[0116] S508: Based on the user's operation on the composition interface, generate a composition including the second door component.

[0117] Optionally, the second door component is initialized and stored locally.

[0118] In summary, when a modification instruction triggered by a user is received, the coordinates of each vertex in the modification object are obtained, and the modification object is the first door component. The preset transformation matrix is ​​called to transform the coordinates of each vertex in the first door component to obtain the coordinates of the new vertex. According to the coordinates of the new vertex, the geometric framework of the second door component is constructed, and the door opening methods of the second door component and the first door component are different. The normal matrix is ​​called to transform the normal vectors of each face in the first door component to obtain the normal vectors of each face of the second door component, wherein the normal matrix is ​​the transposed matrix of the inverse matrix of the transformation matrix. The normal matrix is ​​called to transform the normal vectors of each vertex in the first door component to obtain the normal vectors of each vertex of the second door component. According to the normal vectors of each face of the second door component and the normal vectors of each vertex of the second door component, the surface material and gloss of the second door component are set. The second door component is displayed in the composition interface, and a composition including the second door component is generated based on the user's operation in the composition interface. It can be seen that this embodiment can simply and effectively modify the opening method of the door assembly based on the modification instruction triggered by the user, obtain the composition of the door assembly including different opening methods, and avoid the user from redesigning the door assembly.
