Description

A ShapeTriangleIterator can be used to iterate through all triangles in a MeshShape. The ShapeTriangleIterator itself only serves as a base class; derived classes are provided that deal with differing index layouts depending on the type of the mesh.

ShapeTriangleIterator()

ShapeTriangleIterator	(	const MeshShape &	shape,
		int	startIndex
	)

~ShapeTriangleIterator()

virtual ~ShapeTriangleIterator ( )

virtual

Member Function Documentation

isDone()

bool isDone

(

)

const

Checks whether this iterator is done iterating. next() should only be called while this function returns false.

Returns

true if done iterating, false if not

next()

virtual const ShapeTriangle next ( )

pure virtual

Retrieves the indices of the next triangle in the MeshShape. Should only be called while isDone() returns false.

Returns

the 3 indices of the next triangle in a glm::ivec3

Implemented in ShapeTriangleStripIterator, ShapeTriangleFanIterator, and ShapeTriangleListIterator.
