Volumetric Ray Tracing. Lisa M. Sobierajski and Arie E. Kaufman Department of Computer Science State University of New York at Stony Brook. Abstract This paper presents an eficient ray tracing method for scenes containing volumetric as well as geometric data. A global illumination equation is developed for this method, which is able to capture in a single image both realistic …

https://computergraphics.stackexchange.com/questions/227/how-are-volumetric-effects-handled-in-raytracing
For physically based volumetric light transport, we replace the inconceivably many particles with a continuous participating medium that has two properties: The absorption coefficient, and the scattering coefficient. These coefficients are very convenient for ray tracing, as they allow us to compute the probability of a ray interacting with the ...
Volumetric path tracing - Wikipedia
https://en.wikipedia.org/wiki/Volumetric_Path_Tracing
Volumetric path tracing is a method for rendering images in computer graphics which was first introduced by Lafortune and Willems. This method enhances the rendering of the lighting in a scene by extending the path tracing method with the effect of light scattering. It is used for photorealistic effects of participating media like fire, explosions, smoke, clouds, fog or soft …
Volume Rendering With Ray Casting - WPI
https://web.cs.wpi.edu/~matt/courses/cs563/talks/powwie/p1/ray-cast.htm
When it pertains to volume visualization, ray casting is often referred to as ray tracing. Strictly speaking this is inaccurate, since the method of ray tracing with which most people are familiar is more complex than ray casting. However, the basic ideas of ray casting are identical to those of ray tracing, and the results are very similar.

What is Volume Ray Casting? • Volume Ray Casting is construction of 3D volume using stack of 2D slices. • Since now in Ray Tracing course, when a ray hits to a surface, ray tracing stops for that ray. • In Volume Ray Casting, ray tracing accumulates information until bounding volume is exited or certain stopping criteria holds.
Volume Rendering - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/computer-science/volume-rendering
Volume Rendering. Volume rendering is commonly accomplished using ray-tracing (or ray-casting) techniques. Ray-tracing and ray-casting techniques operate on the principle of defining rays of light from a camera view. The rays behave according to the laws of physics as related to light and optics.
