Also, … Web22 de set. de 2024 · In a 3D renderer, we might want to read the scene normal vectors at some point, for example post processes. We can write them out using MRT - multiple render target outputs from the object rendering shaders and write the surface normals to a texture. But that normal map texture usually contains normals that have…

WebTextures are typically used for images to decorate 3D models, but in reality they can be used to store many different kinds of data. It's possible to have 1D, 2D and even 3D textures, which can be used to store bulk data on the GPU. An example of another use for textures is storing terrain information.
