Constructor & Destructor Documentation

template<class Mesh , class Matrix >

OMProjector::OMProjector	(	MeshT *	mesh,
		OpenMesh::VPropHandleT< MatrixT >	propertyHandle
	)

Constructor - initializes vital variables

Parameters

bool OMProjector::ComputeMatrices	(	ScalarT	length,
		ScalarT	resolution,
		int	zDir = ZDIR_Z,
		bool	lengthRelative = false,
		int	xdirection = XDIR_CURVATURE
	)

Method computes tangent rasters on all the vertices

Parameters

length	Length of a square raster (real length in mesh space)
resolution	Number of pixels on MatrixT edge
zDir	Use ZDIR consts for choose which component will be used as Z direction
xdirection	Direction of X axis on MatrixT (for ex. Maximum curvature direction)
lengthRelative	If true, length is computed as % of median edges lengths, if not, length is static

Returns

True, if computation ended successfully, false otherwise
