WebWe created raymarching materials that repeatedly sample a volume texture along a ray, transfer the read value by a transfer function, take lighting into account and then accumulate the color samples into a final pixel color. All materials used for raymarching are in Content/Materials with M_Raymarch and M_Intensity_Raymarch being the most ... WebJul 1, 2016 · Raymarching with Constant Step. The first implementation of raymarching introduced in Volume Rendering used a constant step. Each ray is extended by STEP_SIZE in the view direction, until it hits something. If that’s the case, we draw red pixel, otherwise a white one. Raymarching with constant step can be implemented with the following code:
