Surface()

Mercator::Surface::Surface ( const Segment &  seg, const Shader &  sh, bool  color = true, bool  alpha = true  )

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.
