In its basic form, the volume ray casting algorithm comprises four steps: 1. Ray casting. For each pixel of the final image, a ray of sight is shot ("cast") through the volume. At this stage it is useful to consider the volume being touched and enclosed within a bounding primitive, a simple geometric object — usually a cuboid — that is used to intersect the ray of sight and the volume.

Web4.1 The four basic steps of volume ray casting: (1) Ray Casting: cast a ray from the viewplane. (2) Sampling: sample the intersected volume along the path of the ray. (3) Shading: compute a color value for each voxel based on a shading model. (4) Compositing: accumulate color and assign to a pixel on the viewplane WebTo cor- our multi-volume ray-casting algorithm in more de- rectly include the geometry colors and opacities in tail. the volume compositing along each ray, intersection calculations would have to be performed at each 3.1 Depth Peeling sample step for all possible surfaces.
