Example 9: Polynomial Texture Maps

A WebGL-enabled browser is needed to run the examples.
Refer to this page for a quick HOWTO.

Description

This demo streams a large multiresolution Polynomial Texture Map, managing an internal cache and a request queue, using frustum culling and projected error for prioritizing hierarchy nodes.
Polynomial Texture Maps are images that can be relighted from different directions.
Data source elaboration and shaders code from Gianpaolo Palma.
