Detailed Description

A m_depth texture can automatically perform the m_depth comparison used for shadow mapping on a texture lookup.

The result of a texture lookup is thus the shadowed amount (which will be percentage closer filtered on newer hardware) and not the actual m_depth from the light's point of view.

This combines GL_TEXTURE_COMPARE_MODE_ARB and GL_TEXTURE_COMPARE_FUNC_ARB from http://www.nvidia.com/dev_content/nvopenglspecs/GL_ARB_shadow.txt

For best results on percentage closer hardware (GeForceFX and Radeon9xxx or better), create shadow maps as m_depth textures with BILINEAR_NO_MIPMAP sampling.

See also G3D::RenderDevice::configureShadowMap and the Collision_Demo.
