Classes

  Type Name Description
Public class FArrowGenerator Generate a 3D arrow  
Public class FBaseRevolveGenerator FBaseRevolveGenerator is a base class for simple surface-of-revolution generators.  
Public class FBoxSphereGenerator Generate a sphere by pushing a boxes vertices onto a sphere often more useful  
Public class FCapsuleGenerator Generate a Capsule mesh, with UVs wrapped cylindrically.  
Public class FCurvedStairGenerator Generate an oriented Curved Stair mesh.  
Public class FCylinderGenerator Generate a cylinder with optional end caps  
Public class FDiscMeshGenerator Generate planar disc (a circle polygon)  
Public class FFlatTriangulationMeshGenerator Generate planar triangulation of a Polygon.  
Public class FFloatingStairGenerator Generate an oriented Floating Stair mesh.  
Public class FGeneralizedCylinderGenerator Sweep a 2D Profile Polygon along a 3D Path.  
Public class FGridBoxMeshGenerator 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  
Public class FLinearStairGenerator Generate an oriented Linear Stair mesh.  
Public class FMarchingCubes    
Public class FMeshShapeGenerator Base class for triangle mesh generators (eg like to generate sphere, cylinder, etc) Subclasses must implement Generate()  
Public class FMinimalBoxMeshGenerator Generate an oriented Box mesh with the smallest number of triangles possible (6 vertices, 12 triangles)  
Public class FPlanarPolygonMeshGenerator Generate planar triangulation of a Polygon.  
Public class FPolygonEdgeMeshGenerator Mesh generator that generates a quad for each edge of a closed polygon  
Public class FProfileSweepGenerator Much like FGeneralizedCylinderGenerator, but allows an arbitrary profile curve to be swept, and gives control over the frames of the sweep curve.  
Public class FPuncturedDiscMeshGenerator Generate planar disc with a hole  
Public class FRectangleMeshGenerator Generate planar rectangular mesh with variable number of subdivisions along width and height.  
Public class FRevolvePlanarPathGenerator Revolve a planar polyline (in the XY plane) around the +Z axis along a circular path (+X, +Y) in the 2D polyline is mapped to (+X, 0, +Z)  
Public class FRevolvePlanarPolygonGenerator Revolve a planar polygon (in the XY plane) around the +Z axis along a circular path (+X, +Y) in the 2D polygon is mapped to (+X, 0, +Z)  
Public class FRoundedRectangleMeshGenerator Adds rounded corners to the rectangle mesh  
Public class FSphereGenerator Generate a sphere mesh, with UVs wrapped cylindrically  
Public class FSpiralRevolvePlanarPolygonGenerator Revolve a planar polygon (in the XY plane) around the +Z axis along a spiral path.  
Public class FSpiralStairGenerator Generate an oriented Curved Stair mesh.  
Public class FStairGenerator Base Stair mesh generator class.  
Public class FSweepGeneratorBase    
Public class FVerticalCylinderGeneratorBase Generate a cylinder with optional end caps
