Webfloat3 rayDirection = float3 (0, 0, 1);// mul (unity_WorldToObject, float4 (normalize (i.vectorToSurface), 1)); it works better but there are new problems such as distorition towards the back. This requires better ray marching algorithm with the step being exactly 1 voxel. I have not had the time to do any further work. 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. bing homepage quiz bhh
