"WebOct 19, 2024 · Texture fetch is an expensive operation. We want to minimize the number of fetches as much as possible. The good news is that our volume is static. The voxels are generated when we create our 3D texture (section Generating a Volume). It’s thus possible to pre-compute all the gradients and save them into another 3D texture.
