Detailed Description

Data store for terrain surface data.

Constructor & Destructor Documentation

explicit

Constructor.

Parameters

seg	the terrain height segment this surface maps on to.
sh	the shader used to generate the surface data.
color	true if this shader contains color data.
alpha	true if this shader contains alpha data.

void Mercator::Surface::populate ( )

Populate the data buffer using the correct shader.

Call the shader to full this surface buffer with surface data.
