Working with objects

Detailed Description

Objects overview

Objects are entities referenced by C3DSceneNode. There are different kind of objects, but they all have a C3DBaseObject base type.
The most important of them are the one which contains the geometry. These one are C3DGeomObject which are subdivided into different type:

• C3DObject which are polygonal objects.
  These are N-Gons which means they can contain a mix of any kind of polygons (triangle, quads, but not only).
• C3DCurve which are simple curves, close or not.
• C3DPatch which are smoothed subdivided objects.
• C3DGroup, C3DCamera, C3DLight...

C3DGeomObject are the one which contains a face list (C3DFaceList), a point list (C3DPointList) and many other lists (CChannel) for handling UVs, normals...
C3DGeomObject offers methods to modify the geometry, invalidate faces, clean the data.

You have access to various graph that gives information about what is connected to what:

• Point graph to know which point is connected to which face.
• Face graph to know which face is connected to which face.
• Edge graph to know which edge is connected to which face.
• And other connections information using C3DGeomObject::GetFacesNeighbourg, C3DGeomObject::GetFacesConnectedToPoints, C3DGeomObject::GetPointsConnectedToEdge, and so on...

You can attach any kind of data to C3DBaseObject using the CCustomData object accessible with C3DBaseObject::GetData.
