WebThe Ray-Marching Algorithm Reading time: 19 mins. The almighty ray-marching algorithm. To integrate incoming light along the ray due to in-scattering, we will break down the volume that the ray passes through into small volume elements and combine the contribution of each of these small volume elements to the overall volume object, a little bit like when we … WebDifferentiable Ray Marching. The decoder generates a volume that contains RGB and opacity values. To render this volume to an image, we use a differentiable ray marching algorithm. The idea is that we integrate the RGB and opacity values through the volume along the ray defined by each pixel. Visualization of differentiable ray marching.
