MR_discreteAbsMeanCurvatureMetric_1()

MRC_API MR_std_function_float_from_MR_EdgeId * MR_discreteAbsMeanCurvatureMetric_1

(

const MR_Mesh *

mesh

)

returns edge's absolute discrete mean curvature as a metric; the metric is minimal in the planar regions of mesh; this metric is symmetric: m(e) == m(e.sym()) Generated from function MR::discreteAbsMeanCurvatureMetric. Parameter mesh can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_function_float_from_MR_EdgeId_Destroy() to free it when you're done using it.

MR_discreteAbsMeanCurvatureMetric_2()

MRC_API MR_std_function_float_from_MR_EdgeId * MR_discreteAbsMeanCurvatureMetric_2	(	const MR_MeshTopology *	topology,
		const MR_VertCoords *	points )

Generated from function MR::discreteAbsMeanCurvatureMetric. Parameter topology can not be null. It is a single object. Parameter points can not be null. It is a single object. Never returns null. Returns an instance allocated on the heap! Must call MR_std_function_float_from_MR_EdgeId_Destroy() to free it when you're done using it.

MR_discreteMinusAbsMeanCurvatureMetric_1()

MRC_API MR_std_function_float_from_MR_EdgeId * MR_discreteMinusAbsMeanCurvatureMetric_1

(

const MR_Mesh *

mesh

)

returns minus of edge's absolute discrete mean curvature as a metric; the metric is minimal in the most curved regions of mesh; this metric is symmetric: m(e) == m(e.sym()) Generated from function MR::discreteMinusAbsMeanCurvatureMetric.
