WebThen, we perform ray marching to sample the simulation result passed in as 3D textures. Ray marching is a GPU-friendly technique for sampling a 3D volume along a ray. Specifically, we generate rays starting at the center of the camera in the direction of each pixel. Then, we calculate whether the ray hits our target volume.
