Detailed Description

Laplacian to smoothly deform a region preserving mesh fine details. How to use:

1. Initialize Laplacian for the region being deformed, here region properties are remembered.
2. Change positions of some vertices within the region and call fixVertex for them.
3. Optionally call updateSolver()
4. Call apply() to change the remaining vertices within the region Then steps 1-4 or 2-4 can be repeated.

Member Function Documentation

apply()

void Laplacian::apply

(

)

takes fixed vertex positions from the points vector passed to a constructor, computes and writes free vertex positions in the points vector passed to a constructor as well

fixVertex() [1/2]

void Laplacian::fixVertex	(	number	v,
		boolean	smooth )

notify Laplacian that given vertex has changed after init and must be fixed during apply;

Parameters

smooth

whether to make the surface smooth in this vertex (sharp otherwise)

fixVertex() [2/2]

void Laplacian::fixVertex	(	number	v,
		Vector3f	fixedPos,
		boolean	smooth )

notify Laplacian that given vertex has changed after init and must be fixed during apply;

Parameters

smooth

whether to make the surface smooth in this vertex (sharp otherwise)

init() [1/2]

void Laplacian::init	(	VertBitSet	freeVerts,
		EdgeWeights	weights )

(re)initialize Laplacian for the region being deformed, here region properties are remembered and precomputed;

Parameters

freeVerts	must not include all vertices of a mesh connected component;
usePoints	is not nullptr, then these points will be used instead of passed to a constructor for weights computation and shape memory

init() [2/2]

void Laplacian::init	(	VertBitSet	freeVerts,
		EdgeWeights	weights,
		VertexMass	vmass,
		RememberShape	rem )

(re)initialize Laplacian for the region being deformed, here region properties are remembered and precomputed;

Parameters

freeVerts	must not include all vertices of a mesh connected component;
usePoints	is not nullptr, then these points will be used instead of passed to a constructor for weights computation and shape memory
