Class	Description

`Geometry`	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. * 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.

`IIndexedVertexElement`	VertexElement with indices data.
`IMeshConvertible`	Entities that implemented this interface can be converted to `Mesh`
`IOrientable`	Orientable entities shall implement this interface.
`Light`	The light illuminates the scene. The formula to calculate the total attenuation of light is: `A = ConstantAttenuation + (Dist * LinearAttenuation) + ((Dist^2) * QuadraticAttenuation)`
`Line`	A polyline is a path defined by a set of points with `Geometry.control_points`, and connected by `Line.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`.
`LinearExtrusion`	Linear extrusion takes a 2D shape as input and extends the shape in the 3rd dimension.
`Mesh`	A mesh is made of many n-sided polygons.
`NurbsCurve`	NURBS curve is a curve represented by NURBS(Non-uniform rational basis spline), A NURBS curve is defined by its `NurbsCurve.order`, a set of weighted `Geometry.control_points` and a `NurbsCurve.KnotVectors` The w component in control point is used as control point’s weight, whatever it is a `CurveDimension.TWO_DIMENSIONAL` or `CurveDimension.THREE_DIMENSIONAL`
`NurbsDirection`	A 3D `NurbsSurface` has two direction, the `NurbsSurface.u` and `NurbsSurface.v`, the `NurbsDirection` defines data for each direction. A direction is actually a NURBS curve, that means it’s also defined by its `NurbsDirection.order`, a `NurbsDirection.KnotVectors`, and a set of weighted control points(defined in `NurbsSurface`).
`NurbsSurface`	`NurbsSurface` is a surface represented by NURBS(Non-uniform rational basis spline), A `NurbsSurface` is defined by two `NurbsDirectionNurbsSurface.u` and `NurbsSurface.v`. The w component in control point is used as control point’s weight whatever the direction’s type is a `CurveDimension.TWO_DIMENSIONAL` or `CurveDimension.THREE_DIMENSIONAL`
`Patch`	A `Patch` is a parametric modeling surface, similar to `NurbsSurface`, it’s also defined by two `PatchDirection`, the `Patch.u` and `Patch.v`. But difference between `Patch` and `NurbsSurface` is that the `PatchDirection` curve can be one of `PatchDirectionType.BEZIER`, `PatchDirectionType.QUADRATIC_BEZIER`, `PatchDirectionType.BASIS_SPLINE`, `PatchDirectionType.CARDINAL_SPLINE` and `PatchDirectionType.LINEAR`
`PatchDirection`	Patch’s U and V direction.
`Plane`	Parameterized plane.
`PointCloud`	The point cloud contains no topology information but only the control points and the vertex elements.
`PolygonBuilder`	A helper class to build polygon for `Mesh`
`PolygonModifier`	Utilities to modify polygons
`Primitive`	Base class for all primitives
`Pyramid`	Parameterized pyramid.
`RectangularTorus`	Parameterized rectangular torus.
`RevolvedAreaSolid`	This class represents a solid model by revolving a cross section provided by a profile about an axis.
`Shape`	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.
`Skeleton`	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 `Skeleton.type` to `SkeletonType.SKELETON`, and all children set to `SkeletonType.BONE`
`Sphere`	Parameterized sphere.
`SweptAreaSolid`	A `SweptAreaSolid` constructs a geometry by sweeping a profile along a directrix.
`Torus`	Parameterized torus.
`TransformedCurve`	A `TransformedCurve` gives a curve a placement by using a transformation matrix. This allows to perform a transformation inside a `TrimmedCurve` or `CompositeCurve`.
`TriMesh`	A TriMesh contains raw data that can be used by GPU directly. This class is a utility to help to construct a mesh that only contains per-vertex data.
`TrimmedCurve`	A bounded curve that trimmed the basis curve at both ends.
`VertexElement`	Base class of vertex elements. A vertex element type is identified by VertexElementType. A VertexElement describes how the vertex element is mapped to a geometry surface and how the mapping information is arranged in memory. A VertexElement contains Normals, UVs or other kind of information.
`VertexElementBinormal`	Defines the binormal vectors for specified components.
`VertexElementDoublesTemplate`	A helper class for defining concrete `VertexElement` implementations.

`VertexElementPolygonGroup`	Defines polygon group for specified components to group related polygons together.
`VertexElementSmoothingGroup`	A smoothing group is a group of polygons in a polygon mesh which should appear to form a smooth surface. Some early 3d modeling software like 3D studio max for DOS used smoothing group to void storing normal vector for each mesh vertex.
`VertexElementSpecular`	Defines specular color for specified components.
`VertexElementTangent`	Defines tangent vectors for specified components.
`VertexElementUV`	Defines the UV coordinates for specified components. A geometry can have multiple `VertexElementUV` elements, and each one have different `TextureMapping`s.
`VertexElementUserData`	Defines custom user data for specified components. Usually it’s application-specific data for special purpose.

`VertexElementVisibility`	Defines if specified components is visible
`VertexElementWeight`	Defines blend weight for specified components.
