Bakkalaureatsarbeit / Praktikum

Description
| |
The aim of this project is to investigate several improvement techniques for real-time global illumination (GI).
Virtual Point Light (VPL)[1] based GI using Imperfect Shadow Maps (ISMs) [3] provides real-time capabilities, but comes with several visual drawbacks.
Virtual Spherical Lights (VSLs) [2] cope with one of these problems, but are too slow for real-time application.
We want to integrate the concept of VSLs into a real-time GI framework, and experiment with various ways to use Imperfect Shadow Maps.

|
Task
| |
Your task is to implement two extensions into an existing framework. You investigate the extension from VPLs to VSLs and try out a different sampling of Imperfect Shadow Maps.
The result is a report on the usability of VSLs and different ISM sampling techniques in terms of performance and visual quality.

|
Requirements
| |
You can either implement within an existing GI-Framework (DirectX, C++), or implement the VPL-based GI algorithm into a OpenGL-Rendering Framework (C++).
Background knowledge to Global Illumination Theory is of advantage, but not necessary.

|
Tools
| |
A fast nVidia Graphics-Card (8800 or GTX Generation) is of advantage. Can also be borrowed from the institute for the duration of the Praktikum.
|
|
Environment
| |
C++, DirectX or OpenGL (depends on framework)
