MR_reducePath()

MRC_API int32_t MR_reducePath	(	const MR_Mesh *	mesh,
		const MR_MeshTriPoint *	start,
		MR_std_vector_MR_EdgePoint *	path,
		const MR_MeshTriPoint *	end,
		const int32_t *	maxIter )

converts any input surface path into geodesic path (so reduces its length): start-path-end; returns actual number of iterations performed Generated from function MR::reducePath. Parameter mesh can not be null. It is a single object. Parameter start can not be null. It is a single object. Parameter path can not be null. It is a single object. Parameter end can not be null. It is a single object. Parameter maxIter has a default argument: 5, pass a null pointer to use it.

MR_reducePathViaVertex()

MRC_API bool MR_reducePathViaVertex	(	const MR_Mesh *	mesh,
		const MR_MeshTriPoint *	start,
		MR_VertId	v,
		const MR_MeshTriPoint *	end,
		MR_std_vector_MR_EdgePoint *	outPath,
		MR_std_vector_MR_Vector2f *	tmp,
		MR_std_vector_MR_EdgePoint *	cachePath )

given path s-v-e, tries to decrease its length by moving away from v

Parameters

outPath	intermediate locations between s and e will be added here
tmp	elements will be temporary allocated here
cachePath	as far as we need two sides unfold, cache one to reduce allocations Generated from function MR::reducePathViaVertex. Parameter mesh can not be null. It is a single object. Parameter start can not be null. It is a single object. Parameter end can not be null. It is a single object. Parameter outPath can not be null. It is a single object. Parameter tmp can not be null. It is a single object. Parameter cachePath can not be null. It is a single object.
