Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For example, the shading on another model is not natural, and shadows appear where no shadows should appear, or light irradiation effects appear where no light is irradiated.

In order to solve the technical problem, embodiments of the present application provide a virtual model rendering method, apparatus, computer device, and storage medium. The virtual model rendering method can improve the rendering effect of the virtual model.

Referring to fig. 1, fig. 1 is a schematic view of an illumination scene according to an embodiment of the present disclosure.

In the real physical world, when light irradiates on the surface of an object, physical phenomena such as refraction and reflection of light occur. When the light source emits light, and the light irradiates one point on the surface of the object, the surface of the object can reflect the light to human eyes.

As shown in fig. 1, a light direction vector corresponding to the light direction is l, a sight direction vector corresponding to the sight direction is v, n is a normal direction vector corresponding to a normal of the surface of the object, the normal direction vector is perpendicular to the surface of the object, h is a half-range vector corresponding to the sight direction vector v and the light direction vector l, r is a reflection direction vector corresponding to the sight direction vector v, and the sight direction vector v reflects with the normal direction vector n as a reference, so as to obtain a reflection direction vector r.

In the embodiment of the application, the corresponding normal data, that is, the corresponding normal direction vector, is set for the first virtual model, so that when the subsequent light effect rendering is performed on the first virtual model, the light rendering effect of different areas of the first virtual model is realized, for example, some areas of the first virtual model have shadows and some areas have light irradiation, so that the light and shadow transition effect close to the real physical world is realized.

The normal data of the different vertices mentioned in the embodiments of the present application may also be artificially set normal directions.

Referring to fig. 2, fig. 2 is a first flowchart of a virtual model rendering method according to an embodiment of the present disclosure. The virtual model rendering method may include the steps of:

110. and determining a target vertex in the multiple vertexes corresponding to the first virtual model and first normal data corresponding to the target vertex.

In some embodiments, the first virtual model is a model to be rendered, and a plurality of vertices are corresponding to the first virtual model, and each vertex of the first virtual model has normal data corresponding thereto, for example, the normal data is a direction of a normal corresponding to each vertex.

In different areas and different positions of the first virtual model, the corresponding vertexes are different, and the normal data between the vertexes is different.

In some embodiments, the computer device may receive a selection instruction, select at least one target vertex from the plurality of vertices of the first virtual model, and obtain normal data corresponding to the at least one target vertex.

Specifically, the computer device may determine at least one target area in the first virtual model; and then determining the vertex in at least one target area as a target vertex, and determining first normal data corresponding to the target vertex from the original normal data of the first virtual model.

For example, a user may select different areas of the first virtual model, and then the computer device determines a target vertex from the vertices of the first virtual model according to the selected position, and obtains normal data corresponding to the target vertex.

After determining a target vertex of the multiple vertices corresponding to the first virtual model and first normal data corresponding to the target vertex, the computer device may determine identification information corresponding to the target vertex, and then store the identification information corresponding to the target vertex and the first normal data corresponding to the target vertex.

For example, the identification information corresponding to the target vertex and the first normal data corresponding to the target vertex are stored in a preset file of a corresponding data structure, so as to be used in a subsequent processing process. The identification information may be position information of the target vertex on the first virtual model, such as three-dimensional coordinates. The identification information may also be the identity information of the target vertices, such as a unique ID for each target vertex.

It should be noted that the first virtual model is provided with original normal data, which may be at least a part of normal data set in advance by a user, for example, normal data set for some areas on the first virtual model where light and shadow transition needs to be implemented, or normal data preset when the first virtual model is set.

120. And acquiring the preset normal data of the second virtual model, and transmitting the preset normal data to the first virtual model to obtain the first virtual model only containing the preset normal data.

In some embodiments, the preset normal data corresponding to the second virtual model may be normal data used by the second preset model in rendering. For example, after the second virtual model is rendered last time, normal data used when the second virtual model is rendered is retained, so that preset normal data is obtained.

In the first virtual model, if corresponding normal data is set for all the vertexes of the first virtual model, the calculation amount required is large, and in order to save the calculation amount, the computer device can directly apply the normal data of the second virtual model to the first virtual model. For example, the preset normal data is transmitted to the first virtual model by a normal transmission mode, so as to obtain the first virtual model only containing the preset normal data.

In the process of normal transmission, if the first virtual model contains original normal data, the computer device determines the original normal data of the first virtual model, and then covers the original normal data with the preset normal data, so as to obtain the first virtual model only containing the preset normal data. That is, only the preset normal data exists in the first virtual model after the normal transfer.

After the normal is transmitted to the first virtual model, if the preset normal data is directly used for rendering the first virtual model, the light and shadow effect of the actually rendered first virtual model is not fine enough, for example, the setting position between the illumination area and the shadow area in the rendered first virtual model is unreasonable, the place with illumination is a shadow, and the place with shadow is illumination. For another example, the transition between the illumination area and the shadow area is not natural enough, so that the light and shadow transition effect of the rendered first virtual model is not fine enough.

In order to solve this problem, in the embodiment of the present application, a part of the area in the first virtual model may be used by using the original normal data corresponding to the area. And in another partial region of the first virtual model, the preset normal data of the second virtual model may be adopted. Therefore, the target normal data of the first virtual model can be rapidly determined in the process of rendering the first virtual model, and meanwhile, the finally rendered first virtual model can have a good rendering effect, for example, the positions of the illumination area and the shadow area are reasonable, and the transition between the illumination area and the shadow area is more natural.

130. And determining second normal data corresponding to the target vertex in the first virtual model only containing the preset normal data.

In some embodiments, the computer device may determine, according to the identification information, a target vertex in the first virtual model that only includes the preset normal data, and then determine, from the preset normal data, second normal data corresponding to the target vertex.

For example, the computer device may obtain a preset file before the first virtual model does not perform normal line transfer, then obtain identification information in the preset file, determine a target vertex in the first virtual model only containing the preset normal line data according to the identification information, and finally determine second normal line data corresponding to the target vertex in the preset normal line data.

The second normal data corresponding to the target vertex and the first normal data corresponding to the target vertex are different.

140. And replacing the second normal data with the first normal data to obtain target normal data corresponding to the first virtual model.

In some embodiments, in order to enable a better rendering effect when the region corresponding to the target vertex of the first virtual model is subsequently subjected to illumination rendering, the computer device may replace the second normal data corresponding to the target vertex with the first normal data. That is, the second normal data of the target vertex is removed and then replaced with the first normal data.

Meanwhile, at other vertices in the first virtual model than the target vertex, the other vertices may adopt normal data in the preset normal data.

And finally, after replacing the normal data of the target vertex in the first virtual model only containing the preset normal data with the first normal data, obtaining target normal data corresponding to the first virtual model, wherein the target normal data is data required to be used when the first virtual model is finally rendered.

150. And performing light effect rendering on the first virtual model according to the target normal data.

In some embodiments, the computer device may set corresponding light effects for different regions of the first virtual model according to the target normal data, such as some regions set as shadow regions and some regions set as illumination regions.

Because the target vertex in the rendered first virtual model adopts the first normal data, the illumination effect of the target area corresponding to the target vertex is better, so that the first virtual model is more careful and natural in overall illumination, and the rendering effect of the first virtual model is improved.

For a more detailed understanding of the virtual model rendering method provided in the embodiment of the present application, please continue to refer to fig. 3, where fig. 3 is a second flow chart of the virtual model rendering method provided in the embodiment of the present application. The virtual model rendering method may include the steps of:

201. at least one target area is determined in the first virtual model.

Referring to fig. 4, fig. 4 is a schematic diagram of a first virtual model according to an embodiment of the present disclosure.

As shown in fig. 4, the first virtual model includes a plurality of vertices, and the positions of the vertices in different regions are different, and the user can select the plurality of regions on the first virtual model to determine the target region.

As shown in FIG. 4, the first virtual model includes two target regions, each of which includes a corresponding target vertex.

For selection of the target region, one target region may be selected, or a plurality of target regions may be selected.

202. Determining a vertex in at least one target area as a target vertex, and determining first normal data corresponding to the target vertex from the original normal data of the first virtual model.

As shown in fig. 4, the computer device may determine a vertex in the corresponding target area as a target vertex, and then determine first normal data corresponding to the target vertex from the original normal data corresponding to the first virtual model.

For example, the computer device may obtain identification information of each target vertex, and then determine the first normal data from the original normal data according to the identification information.

In some embodiments, after the target vertices are determined, corresponding first normal data may also be set separately for each target vertex. For example, the computer device may obtain the normal data set by the user for each target vertex, and then determine the normal data as the first normal data corresponding to each target vertex.

203. And determining identification information corresponding to the target vertex, and storing the identification information corresponding to the target vertex and the first normal data corresponding to the target vertex.

The identification information may be position information of the target vertex on the first virtual model, such as three-dimensional coordinates. The identification information may also be the identity information of the target vertices, such as a unique ID for each target vertex.

In some embodiments, the computer device may store the identification information corresponding to the target vertex and the first normal data corresponding to the target vertex in a preset file of a corresponding data structure for use in a subsequent processing procedure.

For example, the preset file includes a point _ list variable and an origin _ normal variable, and the point _ list variable includes ID information, such as an ID value, of each target vertex. The origin _ normal variable includes normal data corresponding to each target vertex, for example, the computer device may determine first normal data from the original normal data corresponding to the first virtual model by using the ID information of each target vertex, and then store the first normal data in the origin _ normal variable, and store the ID information of each target vertex in the origin _ normal variable.

In some implementations, the computer device may establish a mapping relationship between the identification information of each target vertex and the first normal data, and then save the identification information of each target vertex and the first normal data according to the mapping relationship.

For example, a mapping relationship is correspondingly formed between the target vertex 1 and the first normal data 1, a mapping relationship is correspondingly formed between the target vertex N and the first normal data N, and the computer device may store the identification information of the target vertex and the first normal data according to the mapping relationship, so that the unique first normal data corresponding to the target vertex can be determined according to the identification information in the subsequent data search.

204. And acquiring the preset normal data of the second virtual model, and transmitting the preset normal data to the first virtual model to obtain the first virtual model only containing the preset normal data.

In some embodiments, the preset normal data corresponding to the second virtual model may be normal data used by the second virtual model when rendering is performed. For example, after the second virtual model is rendered last time, normal data used when the second virtual model is rendered is retained, so that preset normal data is obtained.

Referring to fig. 5, fig. 5 is a schematic diagram of normal data transmission according to an embodiment of the present disclosure.

The computer device may first obtain the preset normal data of the second virtual model, obtain the original normal data of the first virtual model and the first virtual model, then transfer the preset normal data to the first virtual model through spherical normal transfer, and simultaneously remove the original normal data in the first virtual model by covering, thereby obtaining the first virtual model only containing the preset normal data.

205. And determining a target vertex in the first virtual model only containing the preset normal data according to the identification information.

In some embodiments, the number and position of vertices in the first virtual model containing only the preset normal data are unchanged, i.e. the identification information of vertices in the first virtual model containing only the preset normal data is unchanged.

Therefore, the computer device may determine the target vertex in the first virtual model containing only the preset normal data according to the identification information. For example, the target vertex is determined in the first virtual model containing only the preset normal data by ID information or position information.

206. And determining second normal data corresponding to the target vertex in the preset normal data.

The computer device may determine normal data corresponding to the target vertex from the preset normal data, and then determine the normal data as second normal data.

207. The second normal data is replaced with the first normal data.

208. Vertices other than the target vertex are determined in the first virtual model containing only the pre-set normal data.

For example, in the first virtual model containing only the preset normal data, there are 100 vertices, and after 30 vertices are determined as target vertices, the remaining 70 vertices are other vertices except the target vertices.

209. And determining third normal data corresponding to other vertexes in the preset normal data.

In some embodiments, the computer device may obtain identification information corresponding to other vertices, and then determine third normal data corresponding to other vertices in the preset normal data according to the identification information.

210. And determining the first normal data and the third normal data as target normal data corresponding to the first virtual model.

As can be seen from the above, the normal data corresponding to the target vertex of the first virtual model is the first normal data, and the normal data corresponding to the vertices other than the target vertex in the first virtual model is the third normal data. Normal data corresponding to all final vertexes of the first virtual model are obtained, that is, the first normal data and the third normal data are determined as target normal data corresponding to the first virtual model. And rendering the first virtual model through the target normal data in the subsequent rendering process.

211. And performing light effect rendering on the first virtual model according to the target normal data.

After the normal is transmitted to the first virtual model, if the preset normal data is directly used for rendering the first virtual model, the light and shadow effect of the actually rendered first virtual model is not fine enough, for example, the setting position between the illumination area and the shadow area in the rendered first virtual model is unreasonable, the place with illumination is a shadow, and the place with shadow is illumination. For another example, the transition between the illumination area and the shadow area is not natural enough, which results in a less detailed light-shadow transition effect of the rendered first virtual model.

Referring to fig. 6, fig. 6 is a first rendering schematic diagram of a first virtual model according to an embodiment of the present disclosure.

The first virtual model in fig. 6 is a rendered first virtual model obtained after rendering is performed directly using the preset normal data. Wherein in the target region, a shadow region exists in a region from the eyes to the nose, and no shadow region exists above the region from the eyes to the nose. This creates a light illumination effect that is not present in the real physical world, resulting in the illumination effect of the rendered first virtual model appearing unrealistic.

Referring to fig. 7, fig. 7 is a second rendering schematic diagram of the first virtual model according to the embodiment of the present disclosure.

The first virtual model in fig. 7 is a rendered first virtual model obtained after rendering using the target normal data. In the target region, there is no shaded region in the region from the eye to the nose as in fig. 6, and there is no shaded region above the region from the eye to the nose. Therefore, the physical world light irradiation effect close to reality is achieved, the illumination effect of the rendered first virtual model looks more real, and the rendering effect of the first virtual model is improved.

In an embodiment of the application, the computer device determines at least one target area in the first virtual model. And then determining a vertex in at least one target area as a target vertex, and determining first normal data corresponding to the target vertex from the original normal data of the first virtual model. And then determining the identification information corresponding to the target vertex, and storing the identification information corresponding to the target vertex and the first normal data corresponding to the target vertex.

And then acquiring preset normal data of the second virtual model, and transmitting the preset normal data to the first virtual model to obtain the first virtual model only containing the preset normal data. And determining a target vertex in the first virtual model only containing the preset normal data according to the identification information. And determining second normal data corresponding to the target vertex in the preset normal data.

And finally replacing the second normal data with the first normal data. Vertices other than the target vertex are determined in the first virtual model containing only the pre-set normal data. And determining third normal data corresponding to other vertexes in the preset normal data. And determining the first normal data and the third normal data as target normal data corresponding to the first virtual model. And performing light effect rendering on the first virtual model according to the target normal data. The first virtual model is rendered by using the preset normal data of the second virtual model and the first normal data of the first virtual model, so that the rendering effect of the first virtual model is improved.
