WebVolume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D … Webraymarching is not raytracing, a raytracer intersects the world in 1 function: when marching the 'scene' function only computes the distance to the current ray 'position' it does not know which direction we are moving, the main loop moves the ray instead: this is much cheaper because intersection maths are not hardware supported in a GPU */
