Geometry Primitives

These primitive presets can be used with either primitive-creating functions (X3DObject.AddPrimitive method, GetPrim and SIGetPrim commands) or geometry-creating functions (X3DObject.AddGeometry method, CreatePrim and DrawPrimitiveTool).

Note	See Primitive Presets for list of the possible types of primitives. Also see Alphabetical Listing of All Primitive Presets for a complete list of available primitive types.

Preset	Primitives
Cone	Cones can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Cube	Cubes can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Cylinder	Cylinders can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Disc	Discs can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Dodecahedron	Dodecahedrons are PolygonMeshes.
Grid	Grids can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Icosahedron	Icosahedrons are PolygonMeshes.
Null	Nulls are objects that have no geometry, but do have a position in space. They are useful for organizing scenes into hierarchies and when used as control objects in a character rig.
Octahedron	Octahedrons are PolygonMeshes.
Rhombicosidodecahedron	Rhombicosidodecahedrons are PolygonMeshes.
SoccerBall	Soccer Balls are PolygonMeshes.
Sphere	Spheres can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
Tetrahedron	Tetrahedrons are PolygonMeshes.
Text	3D Text information is immediately converted to curves which can be optionally converted to planar or extruded PolygonMeshes. Strictly speaking, text is not a true type of geometric object in XSI but can still be created using the geometry-creating X3DObject.AddGeometry method and the CreatePrim and DrawPrimitiveTool commands. Also see the CreateMeshText command.
Torus	Toruses can be PolygonMeshes, NurbsSurfaceMeshes, PointCloudGeometry objects, or implicit objects (non-renderable shapes commonly used to define bounding volumes for envelopes, particles, etc.)
