Detailed Description

An AbstractTask to draw a terrain.

This task draws a mesh for each visible leaf quad of the terrain quadtree, using the current program and framebuffers. Before drawing each quad, this task calls TileSampler::setTile on each TileSampler associated with the TerrainNode in its owner SceneNode. It also calls the Deformation::setUniforms methods using the terrain deformation.
