In the geometry of computer graphics, a vertex normal at a vertex of a polyhedron is a directional vector associated with a vertex, intended as a replacement to the true geometric normal of the surface. Commonly, it is computed as the normalized average of the surface normals of the faces that contain that vertex. The average can be weighted for example by the area of the face or it can be unweighted. Vertex normals can also be computed for polygonal approximations to surfaces such as NURBS, or specified explicitly for artistic purposes. Vertex normals are used in Gouraud shading, Phong shading and other lighting models. Using vertex normals, much smoother shading than flat shading can be achieved; however, without some modifications, it cannot produce a sharp edge.
Method, device and equipment for rendering laser effect, and storage medium
The application provides a laser effect rendering method, device and equipment and a storage medium, which are characterized in that the method determines the vertex normal in the line-of-sight space based on the vertex normal of the light model, samples the laser map with the vertex normal in the line-of-sight space, obtains a first texture map, and then renders the model with the sampled first texture map and a second texture map in the light model, so as to simulate the laser material through the light model. In this way, the sampling and calculation amount is greatly reduced, the performance overhead is reduced, the frame rate of game running is improved, the rendering efficiency is improved, and a basis is provided for the development of a mobile game.
