FDiscMeshGenerator::FDiscMeshGenerator ( )

Member Function Documentation

◆ Generate()

FMeshShapeGenerator & FDiscMeshGenerator::Generate ( )

overridevirtual

Generate the disc

Implements UE::Geometry::FMeshShapeGenerator.

Reimplemented in UE::Geometry::FPuncturedDiscMeshGenerator.

◆ MakeVertex()

FVector3d UE::Geometry::FDiscMeshGenerator::MakeVertex	(	double	x,
		double	y
	)

inline

Create vertex at position under IndicesMap, shifted to Origin

Member Data Documentation

◆ AngleSamples

int UE::Geometry::FDiscMeshGenerator::AngleSamples

Number of vertices around circumference

◆ bSinglePolygroup

bool UE::Geometry::FDiscMeshGenerator::bSinglePolygroup = false

If true, output mesh has a single polygroup, otherwise each quad/tri gets a separate group

◆ EndAngle

float UE::Geometry::FDiscMeshGenerator::EndAngle

End of angle range spanned by disc, in degrees

◆ IndicesMap

FIndex2i UE::Geometry::FDiscMeshGenerator::IndicesMap

How to map 2D indices to 3D. Default is (0,1) = (x,y,0).

◆ Normal

FVector3f UE::Geometry::FDiscMeshGenerator::Normal

Normal vector of all vertices will be set to this value. Default is +Z axis.

◆ RadialSamples

int UE::Geometry::FDiscMeshGenerator::RadialSamples

Number of vertices along radial spokes

◆ Radius

float UE::Geometry::FDiscMeshGenerator::Radius

Radius

◆ StartAngle

float UE::Geometry::FDiscMeshGenerator::StartAngle

Start of angle range spanned by disc, in degrees
