Let's consider when we render a primitive node like a cube, for example. How this cube is constructed in term of geometry, not syntax in Inventor? In other word, what build a primitive node like that cube? 2. When building a scene, as we know, we construct a tree. I am interested in considering only about geometry, (other nodes like property nodes can be ignored in this discussion). Now, consider a subtree that describe the geometry of the scene. I would like to know how actually this tree is constructed. If these any dependencies among its children? 3. Consider a tree that represents a scene, now we travel this tree and render a long the way. Is this true if : the more we go down the tree, the more details of the scene we can render ? I know the "Level of detail" node, but this node doesn't suit my needs. I am really appreciated your helps. Best regards, Hong Quang
