	Writes the double amount of vertices from source to target to produce a more fine grained mesh, we do this several times to get a extreme fine mesh for ode.

void	fillIndexArray (unsigned int lod, INDEX_ARRAY *target)
	Fills a index array in a vrsode::TriangleData with indizes which are suitable for a vertex array which is generated by the Nurbs or which was produces by cutting it out of such one.
template<class ITER, class FLOAT_ARRAY>
void	convertVertices (const ITER &begin, const ITER &end, FLOAT_ARRAY *target)
	Converts VRS::Vectors into plain old floats or something like that so we can give it to the Trimesh API.
Private Attributes
VRS::SO< vrsode::CollisionBody >	m_trimeshBody
VRS::SO< vrsode::TriangleData >	m_triangleData
VRS::SO< VRSTerrainLoader >	m_vrsLoader
	A SO to the VRSTerrainLoader so we can directly access its vertex array for the mesh access.

Detailed Description

This TerrainLoader is for ODE (vrsode) and manipulates a TrimeshShape so that ODE always has the right CollisionBody for the Terrain.

Constructor & Destructor Documentation

random_racer::ODETerrainLoader::ODETerrainLoader	(	VRS::SO< VRS::SceneThing >	thing,
		VRS::SO< VRSTerrainLoader >	vrsLoader,
		double	boxSize,
		double	viewSize
	)

Ctor, for the other params see TerrainLoader::TerrainLoader().

Parameters:

	thing	The SceneThing into which our CollisionBody will be hanged, so it should not be used for something else.
	vrsLoader	The VRSTerrainLoader will be used to extract points from its mesh so we can generate a fine ODE Terrain.
