Constructor & Destructor Documentation

◆ CSectionMeshTriangulate() [1/2]

CSectionMeshTriangulate::CSectionMeshTriangulate	(	double	dMinAngle = `20`,
		double	dMaxArea = `1`
	)

Set the mesh quality parameters.

Parameters

dMinAngle	Minimum angle between two triangle edges generated by the triangulator. Increasing is value will result in a higher quality mesh but more elements. If this value is too high the mesh generator will hang.
dMaxArea	Maximum size of triangle generated by the triangulator. Decreasing this value will result in more elements in the mesh. The value is normalised with the area of the total section. Thus a value of 0.1 will not create any triangles with an area greater than 0.1 times the the area of the section.

Member Function Documentation

◆ Copy()

CSectionMesh * TexGen::CSectionMeshTriangulate::Copy ( ) const

inlinevirtual

This is a function to allow copying of derived classes correctly.

Derived classes should implement this as CSectionMesh* Copy() const { return new CSectionMeshDerived(*this); } where CSectionMeshDerived should be replaced by the name of the derived class

Implements TexGen::CSectionMesh.
