Overview


These pages cover some basic concepts of physically-based lighting, shading, and rendering. Understanding these concepts will help you use V-Ray tools to their full potential.

 

Adaptive Sampling

V-Ray takes a number of samples whenever values are computed during rendering. The number of samples varies on context, making V-Ray an adaptive sampling engine. For an in-depth look at how sampling is implemented and how V-Ray tools can be used to optimize renders, please see the Adaptive Sampling page.

 

Basic Ray Tracing

Ray Tracing is a method for tracing paths of light from the camera. These paths are the basis of V-Ray computations and are used to calculate lighting, shadows, reflections, refractions, etc. For an illustrated guide on how V-Ray uses ray tracing within a scene, please see the Basic Ray Tracing page.

 

Classification of GI Methods

Global Illumination (GI), also known as Indirect Illumination, is comprised of all reflected light in a scene. The Classification of GI Methods page gives an overview of the rendering equation by James T. Kajiya, which is the basis for most modern GI renderers, and describes the different approaches behind calculating GI. This page also discusses each method's advantages and disadvantages, as well as the methods supported by V-Ray.
