Member Function Documentation

void SG_BBox::get	(	MT_Point3 *	box,
		const MT_Transform &	world
	)		const

Get the eight points that define this bounding box.

Parameters:

world

a world transform to apply to the produced points bounding box.

Definition at line 169 of file SG_BBox.cpp.

Referenced by SG_Tree::get(), and SG_Spatial::getBBox().

void SG_BBox::getaa	(	MT_Point3 *	box,
		const MT_Transform &	world
	)		const

Get the eight points that define this axis aligned bounding box. This differs from SG_BBox::get() in that the produced box will be world axis aligned. The maximum & minimum local points will be transformed *before* splitting to 8 points.

Parameters:

world

a world transform to be applied.
