1) Give each chunk an array that represents the light value at each discrete block. A fragment shader runs for every fragment (aka pixel) on screen, tipically using screen coords as input and outputting a color. Code (CSharp): fixed4 c = UNITY_SAMPLE_TEX2DARRAY ( _MainTex, float3 (IN. You need a normal map which is later applied to each voxel face, as well as a detail albedo map which is grey at the edges and white in the center area (to get that grid-like look). Effective Water Simulation from Physical Models. Unity’s NavMesh system also uses voxelization. Hex Map. Probably would do it myself, but the thing is I suck at coding anything that requires dynamic mesh generation and probably would break it beyond repair rather than contribute to. An any-hit shader is potentially executed a lot during ray traversal, and it interrupts the hardware intersection search. DrawProcedural on the output. The term voxel denotes an individual "volume element," similar to the terms pixel for "picture element" and texel for "texture element. You’ve got yourself Cel Shading in Unity 5, but we are still not done to get our next-gen toon look. Of course GPUs only understand triangles so the voxels have to be converted to a mesh some how.
