Constructor & Destructor Documentation

Heightmap::Heightmap ( )

The mesh is stored as reference and used for calculations.

objMesh for building the heightmap.

float Heightmap::getHeight ( const float  x,
const float  y 
) const

In case of ambiguities always returns the maximum height.

z-Value at position given by x and y
