Detailed Description

This represents a heightmap for viewer-ground collision.

Constructor & Destructor Documentation

Heightmap()

Heightmap::Heightmap

(

)

Construct a heightmap from a loaded OBJ mesh.

The mesh is stored as reference and used for calculations.

Parameters

obj	Mesh for building the heightmap.

Member Function Documentation

getHeight()

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

Get z Value at (x,y) coordinates.

In case of ambiguities always returns the maximum height.

Parameters

x	x-value
y	y-value

Returns

z-Value at position given by x and y
