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.
   Generated from class MR::Laplacian.

Instances created here own their C++ objects, see CppObject.

Constructor & Destructor Documentation

Laplacian() [1/4]

meshlib.Laplacian.Laplacian	(	java.lang.foreign.MemorySegment	ptr,
		boolean	owned,
		java.lang.Object	owner )

Wraps a pointer from the C bindings. If owned, the object is destroyed when the wrapper dies. owner is kept alive as long as this wrapper is. Not for normal use.

Laplacian() [2/4]

meshlib.Laplacian.Laplacian

(

meshlib.Laplacian

_other

)

Generated from constructor MR::Laplacian::Laplacian. The reference to things referred to by the parameter _other (if any) might be preserved in the constructed object.

Calls MR_Laplacian_ConstructFromAnother().

Laplacian() [3/4]

meshlib.Laplacian.Laplacian

(

meshlib.Mesh

mesh

)

Generated from constructor MR::Laplacian::Laplacian. The reference to the parameter mesh might be preserved in the constructed object.

Calls MR_Laplacian_Construct().

Laplacian() [4/4]

meshlib.Laplacian.Laplacian	(	meshlib.MeshTopology	topology,
		meshlib.VertCoords	points )

Generated from constructor MR::Laplacian::Laplacian. The reference to the parameter topology might be preserved in the constructed object. The reference to the parameter points might be preserved in the constructed object.

Calls MR_Laplacian_Construct_topology().
