The present disclosure provides a method of three-dimensional rendering, and in particular, a method of three-dimensional rendering of a target object having a color in a virtual data environment. The kind and arrangement of the colors of the target object are not limited.

FIG. 1 illustrates a method of three-dimensional rendering according to an embodiment of the present disclosure, including, as shown:

step S110, obtaining a target object to be rendered, wherein the target object consists of a plurality of unit cubes, and six unit surfaces of each unit cube have colors;

step S120, merging at least one unit surface which is positioned on the same plane, has the same color and fills the rectangular area, and obtaining a target rectangular surface contained in the target object;

And step S130, calling a three-dimensional rendering engine to render the target object by rendering the target rectangle surface.

It should be noted that in the embodiment of the present disclosure, the square is a special rectangle.

The method and the device are mainly applied to a scene of virtual three-dimensional object rendering which interacts with a user, for example, after the user logs in a virtual three-dimensional object control system through a terminal, a target object is built in the system through generating and scheduling unit cubes, and then a cloud server of the system calls a three-dimensional rendering engine to conduct three-dimensional rendering on the target object. Wherein rendering the target object in three dimensions includes rendering a general representation of the surface of the target object, rendering a representation of the surface of the target object under the influence of ambient light shadows.

For the purpose of facilitating explanation of the embodiments of the present disclosure, in the following description of the embodiments of the present disclosure, a cloud server is exemplified as an execution subject, and a target object to be rendered is exemplified as an application scene by a user identified by the cloud server through generating and scheduling a unit cube.

In the embodiment of the disclosure, the obtained target object to be rendered is composed of a plurality of unit cubes, wherein six unit faces of each unit cube have colors. Generally, the colors of the six unit planes of a single unit cube are the same. For example, in a virtual three-dimensional object control system, bricks that are generated and scheduled by a user, each of which is a cube that is a basic unit of a virtual building, have colors. Specifically, there are six blocks with green faces, six blocks with red faces, and six blocks with yellow faces.

In the embodiment of the disclosure, the target object is composed of a plurality of unit cubes, and each unit cube has six unit faces. The target object is rendered, that is, the unit surface that the target object has is rendered. In order to reduce the calculated amount of the three-dimensional rendering engine when rendering the target object, at least one unit surface which is in the same plane, has the same color and fills the rectangular area is combined to obtain a target rectangular surface contained in the target object, and the three-dimensional rendering engine can be further called to render the target object through the rendering target rectangular surface.

In one embodiment, merging at least one unit surface of the same color and filling the rectangular area in the same plane includes:

Selecting a plane to be rendered in the target object as a target plane;

Two unit planes of the same color and sharing two vertices in the target plane are merged two by two based on traversal of vertices of the unit planes in the target plane, wherein each unit plane is merged at most once.

In this embodiment, the combination of at least one unit surface having the same color and filling the rectangular area in the same plane is realized by combining the unit surfaces two by two.

Specifically, the cloud server selects a plane to be rendered in the target object as a target plane, and traverses the vertexes of each unit plane positioned on the target plane, so that it is determined which two unit planes with the same color share two vertexes. Since one unit surface has only four vertexes, if two unit surfaces of the same color share two vertexes, it is explained that the two unit surfaces of the same color together fill one rectangular area, so that the two unit surfaces of the same color are combined. And, each unit surface is merged at most once to avoid merging the same unit surface with two or more other unit surfaces at the same time.

An advantage of this embodiment is that by merging unit planes two by two, a reduction in the number of planes that need to be rendered by the three-dimensional rendering engine can be achieved quickly.

In this embodiment, as shown in fig. 2, at least one unit surface having the same color and filling the rectangular area on the same plane is combined by combining the unit surfaces in pairs.

Specifically, the target plane has 12 unit planes, and each unit plane has a color. Since both the unit surface 1 and the unit surface 2 are red and share two vertices, the unit surface 1 and the unit surface 2 are combined, and in the same way, the unit surface 3 and the unit surface 4, the unit surface 5 and the unit surface 9, the unit surface 10 and the unit surface 11, and the unit surface 8 and the unit surface 12 are combined.

It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and scope of use of the present disclosure.

Selecting a plane to be rendered in the target object as a target plane, and selecting a unit plane from all unit planes positioned in the target plane as a starting plane;

In this embodiment, the merging of at least one unit surface having the same color and filling the rectangular area in the same plane is achieved by the continuous merging of the unit surfaces.

Specifically, the cloud server selects a plane to be rendered in the target object as a target plane, and selects a unit plane from all unit planes in the target plane as a starting plane. And traversing the vertexes of each unit surface positioned on the target plane, taking the initial surface as a merging reference, merging the other unit surfaces into the initial surface every time traversing to other unit surfaces which have the same color as the initial surface and share two vertexes with the initial surface, expanding the area of the initial surface merged with the other unit surfaces, and correspondingly changing the vertexes.

Merging is continued until another unit surface of the same color as the start surface and sharing two vertices with the start surface is not found in the target plane.

Further, the cloud server selects one unit surface from the unit surfaces which are not yet combined and are positioned on the target plane as another initial surface, and combines other unit surfaces which have the same color as the other initial surface and share two vertexes with the other initial surface into the other initial surface by using the other initial surface as a combining reference in the same method.

The advantage of this embodiment is that by continuously merging the unit planes, the degree of merging and continuity is improved, further reducing the number of planes that need to be rendered by the three-dimensional rendering engine.

In this embodiment, as shown in fig. 3, the merging of at least one unit surface having the same color and filling the rectangular area in the same plane is achieved by continuously merging the unit surfaces.

Specifically, the target plane has 12 unit planes, and each unit plane has a color. Taking the unit surface 1 as the initial surface, combining the unit surface 2 into the unit surface 1 because the unit surface 1 and the unit surface 2 are red and share two vertexes, enlarging the area of the unit surface 1 and correspondingly changing the vertexes, and continuously combining the unit surface 3 into the unit surface 1 combined with the unit surface 2 because the unit surface 1 and the unit surface 3 combined with the unit surface 2 are red, enlarging the area of the unit surface 1 again and correspondingly changing the vertexes again. Similarly, the subsequent merging process is not described again.

In this embodiment, at least one unit surface having the same color and filling the rectangular area on the same plane is combined by cyclically combining two independent surfaces.

Specifically, the cloud server may preset a counter to record the number of cycle merging times, and initialize the counter to 0 before the cycle merging starts. Meanwhile, a time threshold is preset, and once the value of the counter reaches the time threshold, loop merging is terminated.

The cloud server selects one plane to be rendered in the target object as a target plane.

In the process of merging in each cycle, the cloud server traverses the vertexes of mutually independent faces positioned on the target plane, so that two mutually independent faces sharing two vertexes and having the same color are merged in pairs. The independent surfaces may be a unit surface a and a unit surface B, which are independent from each other, a unit surface a and a combined surface B, or a combined surface a and a combined surface B, which are independent from each other. And, in the course of merging each cycle, each independent face is merged at most once, in order to avoid the same face to merge with two or more other faces at the same time.

After each cycle of merging is completed, the cloud server adds the value of the counter together to continue the next cycle of merging until the value of the counter reaches the threshold value of the times to terminate the cycle of merging.

An advantage of this embodiment is that by cyclically merging two separate facets, the number of facets that the three-dimensional rendering engine needs to render is nearly minimized, thereby nearly maximizing the operating efficiency of the three-dimensional rendering engine.

In this embodiment, as shown in fig. 4, at least one unit surface having the same color and filling the rectangular area on the same plane is combined by cyclically combining two independent surfaces.

Specifically, the target plane has 12 unit planes, and each unit plane has a color.

During the first round of merging, every two of the 12 mutually independent unit planes are merged. Since the unit surface 1 and the unit surface 2 are red and share two vertexes, the unit surface 1 and the unit surface 2 are combined to obtain a combined surface 13, the unit surface 3 and the unit surface 4 are combined to obtain a combined surface 14, the unit surface 5 and the unit surface 9 are combined to obtain a combined surface 15, the unit surface 10 and the unit surface 11 are combined to obtain a combined surface 16, and the unit surface 8 and the unit surface 12 are combined to obtain a combined surface 17.

In the second cycle of merging, two of the faces 13, 14, 15, 7, 9, 16, and 17 are merged. Since both the surfaces 13 and 14 are red and share two vertices, the surfaces 13 and 14 are combined to obtain a combined surface 18.

In one embodiment, the method further comprises:

the merging sequence according to the merging of every two loops is kept consistent.

In this embodiment, the cloud server performs pairwise merging according to the same merging sequence in each cycle merging process, so as to ensure the merging order.

Referring to fig. 5, in this embodiment, during each cycle of merging, merging is performed two by two in the same merging order.

Specifically, the target plane has 12 unit planes, and each unit plane has a color. And the preset merging sequence is that merging is firstly carried out from left to right and then merging is carried out from top to bottom.

In the first cycle merging process, the unit faces which are independent of each other are merged in a left-to-right sequence in advance in the first row, so that a face 13 formed by merging the unit face 1 with the unit face 2 is obtained, a face 14 formed by merging the unit face 3 with the unit face 4 is obtained, the unit faces which are independent of each other are merged in a left-to-right sequence in the second row, so that a face 15 formed by merging the unit face 5 with the unit face 6 is obtained, the unit faces which are independent of each other are merged in a left-to-right sequence in the third row, so that a face 16 formed by merging the unit face 10 with the unit face 11 is obtained, and the unit faces which are not merged and are independent of each other are merged in a top-to-bottom sequence in the second row, so that a face 17 formed by merging the unit face 8 with the unit face 12 is obtained.

In the second cycle merging process, the mutually independent faces are merged in the left-to-right sequence before the first row, so that the face 18 after the face 13 and the face 14 are merged is obtained, and in the same way, the mutually independent faces are merged in the left-to-right sequence after the second row, the mutually independent faces are merged in the left-to-right sequence after the third row, and the mutually independent faces are merged in the top-to-bottom sequence.

In one embodiment, selecting a plane to be rendered in the target object as the target plane includes:

acquiring a current visual angle of a user;

In this embodiment, the cloud server preferentially selects the target plane from the current view angle of the user.

Specifically, the cloud server can determine at which view angle the user is currently viewing the target object by reading the state of the virtual identity of the user in the virtual three-dimensional control system. After the current view angle of the user is determined, starting from the view angle, determining the sequence of the planes to be rendered in the view angle as target planes, and selecting the target planes according to the sequence.

For example, the cloud server presets the sequence of selecting the target planes as a plane positioned on the front face of the visual angle, a plane positioned on the left side of the visual angle, a plane positioned on the back face of the visual angle, a plane positioned on the right side of the visual angle, a plane positioned on the top face of the visual angle and a plane positioned on the bottom face of the visual angle.

The user builds a cuboid virtual building to be rendered in the system by using the brick, and the six planes to be rendered of the virtual building are respectively a plane A, a plane B, a plane C, a plane D, a plane E and a plane F.

The cloud server determines that in the current view angle of the user, the face B is located on the front face, the face C is located on the left face, the face D is located on the back face, the face A is located on the right face, the face E is located on the top face and the face F is located on the bottom face by reading the state of the virtual identity of the user in the system.

The cloud server performs unit plane combination by taking the plane B as a target plane, and performs unit plane combination by taking the plane C as the target plane after the combination on the plane B is completed. In the same manner, the planes D, E, and F are sequentially set as target planes, and the unit planes are combined.

The embodiment has the advantage that the rendering of the target object can preferentially meet the visual requirements of the user by preferentially selecting the target plane from the current view of the user.

It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and scope of use of the present disclosure. It will be appreciated that the selection of the target plane may be performed randomly, in addition to preferentially from the current perspective of the user.

In the embodiment of the disclosure, the number of the target rectangular surfaces is smaller than the number of the unit surfaces as long as the merging is successfully performed once, so that the calculated amount required by calling the three-dimensional rendering engine to render the target object through the target rectangular surfaces is smaller than the calculated amount required by calling the three-dimensional rendering engine to render the target object through the unit surfaces, and the running efficiency of the three-dimensional rendering engine is improved.

In one embodiment, before merging at least one unit surface of the same color and filling the rectangular area in the same plane, the method further includes:

And eliminating the unit cubes which are surrounded by other unit cubes on all six unit planes from the target object.

In this embodiment, before merging the unit planes, the cloud server eliminates the unit cubes in which all six unit planes are surrounded by other unit cubes from the target object, that is, eliminates the unit cubes wrapped inside the target object from the target object.

This embodiment has the advantage that the unit cubes wrapped inside the target object can be removed from the target object, since the unit cubes wrapped inside the target object are not visible to the user, and do not need to be rendered from the perspective of the user. Therefore, the calculated amount of the three-dimensional rendering engine is reduced, and the running efficiency of the three-dimensional rendering engine is improved.

In one embodiment, the method further comprises:

and generating and rendering a miniature model of the target object based on the scaling down of the rendered target object.

In this embodiment, after the rendering of the target object is completed, the cloud server reduces the target object in equal proportion according to a preset proportion, generates a miniature model of the target object, and renders the miniature model by the same three-dimensional rendering method.

The embodiment has the advantage that by generating and rendering the miniature model of the target object, the user can watch the whole structure and the whole rendering effect of the target object, and the richness of the visual information of the user is improved.

Referring to fig. 6, in this embodiment, the user builds the target object shown on the left half of fig. 6 by generating and scheduling bricks. The target rectangular surface is obtained by merging at least one unit surface which is positioned on the same plane and has the same color and is filled in the rectangular area, the target object is rendered by calling a three-dimensional rendering engine through rendering the merged target rectangular surface, the rendering effect is shown on the right side of fig. 6, the target object is reduced in an equal proportion, and a miniature model of the target object is generated and rendered, as shown on the right side of fig. 6.
