Deferred Voxel Shading for Real Time Global Illumination
Since we voxelize the geometry normal vectors and the albedo into 3D textures , all the needed information for the indirect diffuse term is available after calculating the voxel direct illumination .
For high-quality rendering , the diffuse indirect illumination is computed by shooting rays to sample the hemisphere above each point. This particular use of distribution ray tracing [CPC84] is often called final gathering [Rei92]. Final gathering is a time-consuming computation, but it is made much more efficient by interpolation of the computed diffuse indirect illumination results using ...
Light Paths
Approximate diffuse indirect light with background tinted ambient occlusion. This provides fast alternative to full global illumination (GI), for interactive viewport rendering or final renders with reduced quality.
This makes the method tractable for real-time rendering of arbitrary dy-namic environments and for interactive preview of feature anima-tions. Through DRM we simulate two diffuse re ections of light, but can also, in combination with traditional real-time methods for specular re ections, simulate more complex light paths.
Chapter 14. Dynamic Ambient Occlusion and Indirect Lighting
Furthermore, visual representations like the one above help us fully grasp the concept of D Indirect Diffuse Texture Illumination Rendering.
Chapter 14. Dynamic Ambient Occlusion and Indirect Lighting Michael Bunnell NVIDIA Corporation In this chapter we describe a new technique for computing diffuse light transfer and show how it can be used to compute global illumination for animated scenes. Our technique is efficient enough when implemented on a fast GPU to calculate ambient occlusion and indirect lighting data on the fly for ...
PDF Dynamic Ambient Occlusion and Indirect Lighting
Global illumination techniques such as ambient occlusion and indirect lighting greatly enhance the quality of rendered diffuse surfaces. We have presented a new technique for calculating light transfer to and from diffuse surfaces using the GPU.
DDGI Implementation Relevant source files Purpose and Scope This document details the implementation of Dynamic Diffuse Global Illumination (DDGI) within the LuxGI framework. DDGI is a probe-based global illumination technique that provides real-time diffuse indirect lighting for dynamic scenes.
PDF Dynamic Diffuse Global Illumination with Ray
Options The Indirect Lighting panel contains two options: Factor Defines how much surrounding objects contribute to light. Bounces Number of indirect diffuse light bounces. The Gather panel contains settings for the indirect lighting quality. Note that these settings also apply to Environment Lighting and Ambient Occlusion.
