Public classGeometry
The base class of all renderable geometric objects (like Mesh, NurbsSurface, Patch and etc.).

The Geometry base class supports:
  • Control point management, control points defines the base 3D spatial structure of the geometry, different geometric types has different way to define concrete 3D models.
  • Vertex element definition, vertex elements applies extra information like normals/uv coordinates/vertex colors to the geometry, see VertexElement for more details.
  • Object deforming, Deformer can be bonded to animate geometry's shape.
Public classLight
The light illuminates the scene.

The formula to calculate the total attenuation of light is: A = ConstantAttenuation + (Dist * LinearAttenuation) + ((Dist^2) * QuadraticAttenuation)
Public classLine
A polyline is a path defined by a set of points with ControlPoints, and connected by Segments, which means it can also be a set of connected line segments. The line is usually a linear object, which means it cannot be used to represent a curve, in order to represent a curve, uses NurbsCurve.
Public classLinearExtrusion

Public classCode exampleMesh
A mesh is made of many n-sided polygons.
Public classNurbsCurve
NURBS curve is a curve represented by NURBS(Non-uniform rational basis spline), A NURBS curve is defined by its Order, a set of weighted ControlPoints and a KnotVectors The w component in control point is used as control point's weight, whatever it is a TwoDimensional or ThreeDimensional
Public classNurbsDirection
A 3D NurbsSurface has two direction, the U and V, the NurbsDirection defines data for each direction. A direction is actually a NURBS curve, that means it's also defined by its Order, a KnotVectors, and a set of weighted control points(defined in NurbsSurface).
Public classNurbsSurface
NurbsSurface is a surface represented by NURBS(Non-uniform rational basis spline), A NurbsSurface is defined by two NurbsDirectionU and V. The w component in control point is used as control point's weight whatever the direction's type is a TwoDimensional or ThreeDimensional
Public classPatch
A Patch is a parametric modeling surface, similar to NurbsSurface, it's also defined by two PatchDirection, the U and V. But difference between Patch and NurbsSurface is that the PatchDirection curve can be one of Bezier, QuadraticBezier, BasisSpline, CardinalSpline and Linear

Public classRectangularTorus
Parameterized rectangular torus.
Public classRevolvedAreaSolid
This class represents a solid model by revolving a cross section provided by a profile about an axis.
Public classShape
The shape describes the deformation on a set of control points, which is similar to the cluster deformer in Maya. For example, we can add a shape to a created geometry. And the shape and the geometry have the same topological information but different position of the control points. With varying amounts of influence, the geometry performs a deformation effect.
Public classSkeleton
The Skeleton is mainly used by CAD software to help designer to manipulate the transformation of skeletal structure, it's usually useless outside the CAD softwares. To make the skeleton hierarchy acts like one object in CAD software, it's necessary to mark the top Skeleton node as the root one by setting Type to Skeleton, and all children set to Bone
Public classSphere

Public classSweptAreaSolid
A SweptAreaSolid constructs a geometry by sweeping a profile along a directrix.
