#include <MeshGenParams.h>
This class serves as container for mesh generator parameters. Client code can provide a class which derives from MeshGenParams an which provides custom implementations of the getMaxTriangleArea(Triangle* pT) method or the getMaxEdgeLength(Triangle* pT) method in order to gain control over the local density of the generated mesh. When the meshing algorithm decides if a certain triangle T must be refined, then it calls these functions.
virtual double GEOM_FADE2D::MeshGenParams::getMaxEdgeLength 
( 
Triangle2 * 
pT  ) 


inlinevirtual 
 Parameters

pT  is a triangle for which the meshing algorithm checks if it must be refined. 
The default implementation of the present class returns the value maxEdgeLength (which is DBL_MAX if not changed by the user). This method can be overridden by the client software in order to control the local mesh density.
User Controlled Mesh Density, Edge Length
virtual double GEOM_FADE2D::MeshGenParams::getMaxTriangleArea 
( 
Triangle2 * 
pT  ) 


inlinevirtual 
 Parameters

pT  is a triangle for which the meshing algorithm checks if it must be refined. 
The default implementation of the present class returns the value maxTriangleArea (which is the default value DBL_MAX if not changed by the user). This method can be overridden by the client software in order to control the local mesh density.
User Controlled Mesh Density, Area
bool GEOM_FADE2D::MeshGenParams::bAllowConstraintSplitting 
Defines if constraint segments can be splitted. Default: yes
double GEOM_FADE2D::MeshGenParams::capAspectLimit 
Limits the quotient edgeLength / height. Default value: 10.0
int GEOM_FADE2D::MeshGenParams::command 
A command for development, not for public use. Will vanish soon.
double GEOM_FADE2D::MeshGenParams::gridLength 
Set gridLength > 0 to mesh large enough areas with grid points. Border areas and narrow stripes where a grid does not fit are automatically meshed using classic Delaunay methods. By default gridLength=0 (off).
 Note
 The length of the diagonals in the grid is sqrt(2)*gridLength and the algorithm may automatically adapt the gridLength a bit such that the grid fits better into the shape.
Grid Meshing axis aligned
Vector2 GEOM_FADE2D::MeshGenParams::gridVector 
When premeshing with grid points is used then the grid will be aligned along this vector. By default gridVector is axis aligned.
Grid Meshing along Vector2(1.0,0.3)
double GEOM_FADE2D::MeshGenParams::growFactor 
Limits the growth of adjacent triangles. The mesh is constructed such that for any two adjacent triangles t0 and t1 (where t0 is the larger one) area(t0)/area(t1) < growFactor. Recommendation: growFactor>5.0, Default: growFactor=DBL_MAX
double GEOM_FADE2D::MeshGenParams::growFactorMinArea 
The growFactor value is ignored for triangles with a smaller area than growFactorMinArea. This value prevents generation of hundreds of tiny triangles around one that is unusually small. Default: 0.001
double GEOM_FADE2D::MeshGenParams::maxEdgeLength 
This value is returned by the default implementation of getMaxEdgeLength(Triangle* pT). Larger edges are automatically subdivided. If a custom implementation of getMaxEdgeLength(Triangle* pT) is provided then this value is ignored. Default value: DBL_MAX.
double GEOM_FADE2D::MeshGenParams::maxTriangleArea 
This value is returned by the default implementation of getMaxTriangleArea(Triangle* pT). Larger triangles are automatically subdivided. If a custom implementation of getMaxTriangleArea(Triangle* pT) is provided then this value is ignored. Default value: DBL_MAX.
double GEOM_FADE2D::MeshGenParams::minAngleDegree 
Minimum interior angle: Default: 20.0, maximum: 30.0
double GEOM_FADE2D::MeshGenParams::minEdgeLength 
Edges below the minimum length are not subdivided. This parameter is useful to avoid tiny triangles. Default: 0.001
