I want to add VXGI(voxel global illumination) to my project. So I must voxelize the game scene( which is composed with triangles ).
I want to use the (vertex-fragment)rendering pipeline to do the rasterization automatically, and then use the fragment information to fill the 3D Texture( which is used to store the information of the voxelized scene ).
How to write data to a pixel of a 3D Texture in my frag shader? just like the function “imageStore” in OpenGL? thanks a lot.
I am using unity 2022.3.8. and URP.
