Detailed Description

Generate a mesh of a box that has "gridded" faces, i.e. grid of triangulated quads, with EdgeVertices setting the number of verts along each edge in each dimension

Member Function Documentation

◆ Generate()

virtual FMeshShapeGenerator & UE::Geometry::FGridBoxMeshGenerator::Generate ( )
inlineoverridevirtual

Generate the mesh

Implements UE::Geometry::FMeshShapeGenerator.

Reimplemented in UE::Geometry::FBoxSphereGenerator.

Member Data Documentation

◆ Box

FOrientedBox3d UE::Geometry::FGridBoxMeshGenerator::Box

3D box

◆ bPolygroupPerQuad

bool UE::Geometry::FGridBoxMeshGenerator::bPolygroupPerQuad = false

If true, each quad of box gets a separate polygroup

◆ bScaleUVByAspectRatio

bool UE::Geometry::FGridBoxMeshGenerator::bScaleUVByAspectRatio = true

If true (default), UVs are scaled so that there is no stretching. If false, UVs are scaled to fill unit square

◆ EdgeVertices

FIndex3i UE::Geometry::FGridBoxMeshGenerator::EdgeVertices { 8,8,8 }
