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. maypole primary school kent

WebJul 1, 2024 · The only reason to use geometry is for using the GPU’s rasterization. For raymarching the 3D texture is already a far more optimal format. Otherwise if you really want to convert a 3D texture or any form of voxel data into a mesh, it’s really mostly just brute force iteration over the cells and generating box geometry from that.
