unsafe void Sandbox.Engine.Voxels.MyPlanetShapeProvider.GetBounds	(	Vector3 *	localPoints,
		int	pointCount,
		out float	minHeight,
		out float	maxHeight
	)

inline

Get the minimum and maximum ranges of terrain height in the area determined by the provided points.

Parameters

localPoints	List of points to query
pointCount	Number of points
minHeight	The calculated minimum possible height of terrain
maxHeight	The calculated maximum possible height of terrain

unsafe void Sandbox.Engine.Voxels.MyPlanetShapeProvider.GetBounds ( ref BoundingBox box )

inline

Takes the x and y bounds of the box and queries the heightmap for the minimum and maximum height in the box.

The values are returned in the query box itself as the Z bounds.

This only works if all vertices of the box are in the same face.

void Sandbox.Engine.Voxels.MyPlanetShapeProvider.PrepareCache ( )

inline

The cache does not store in it's cells which map does one cell belong to, so before using it we have to invalidate all entries.

Maybe at some point we can come up with a more elegant solution for multiple planets.
