WebAug 5, 2024 · Voxel Cone Tracing is similar to Ray Marching in the sense that we trace a few rays, and march across them until we hit obstacles. But instead of sending hundreds of rays, we only trace 4 to 6 ‘rays’ (called cones) and use 3D mipmapping to detect obstacles further away. Tracing a ‘cone’, as we move away from origin, we increase the cone ... WebThe background.
