Function Documentation

mrPointCloudAddPoint()

MRMESHC_API MRVertId mrPointCloudAddPoint	(	MRPointCloud *	pc,
		const MRVector3f *	point_ )

appends a point and returns its VertId

mrPointCloudAddPointWithNormal()

MRMESHC_API MRVertId mrPointCloudAddPointWithNormal	(	MRPointCloud *	pc,
		const MRVector3f *	point_,
		const MRVector3f *	normal_ )

mrPointCloudComputeBoundingBox()

MRMESHC_API MRBox3f mrPointCloudComputeBoundingBox	(	const MRPointCloud *	pc,
