Function Documentation

subdivide()

void subdivide	(	Mesh &	mesh,
		unsigned int	level )

Method to refine and smooth a mesh using Charles Loop method (it divides each triangle into 4 smaller ones)

Parameters

[in,out]	mesh	Mesh
[in]	level	Number of refinement steps

Note

Consider removing duplicated vertices by calling Cleaning::mergeCloseVertices before this

Warning

Mesh properties will be outdated after this call

smooth()

void smooth	(	Mesh &	mesh,
		unsigned int	iter,
		SmoothMode	mode = SmoothMode::Laplacian )

Mesh smoothing algorithm.

Parameters

[in,out]	mesh	Mesh
[in]	iter	Number of smoothing iterations
[in]	mode	Smoothing method

Note

Consider removing duplicated vertices by calling Cleaning::mergeCloseVertices before this

simplify()

void simplify	(	Mesh &	mesh,
		const SimplificationSettings &	settings,
		const std::vector< int > &	blockedVertices = {} )

Mesh simplification algorithm.

Simplification stops after running out of valid edge collapse choices. Based mostly on triangle edge lengths, with optional preservation of mesh curvature, vertex colors and normals.

Parameters

[in,out]	mesh	Mesh
[in]	settings	Algorithm settings
[in]	blockedVertices	Vertices that should remain untouched during simplification

Note

Consider removing duplicated vertices by calling Cleaning::mergeCloseVertices before this
