Ray casting-based method
WebThere is more than one volume rendering technique, and the correct one for your application depends on several factors. 3D volume rendering methods can be grouped into four categories: ray casting or raymarching, resampling or shear-warp, texture slicing, and splatting. Direct volume rendering ray casting is typically achieved as follows.

These … WebMar 15, 2024 · Comparing with the existing MIB scheme, the ray-casting scheme naturally bypasses the corner issue and becomes more robust in handling complex geometry. …
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.
