IDirect3DRMVisual and IDirect3DRMVisualArray Interfaces
Visuals are objects that can be rendered in a scene. Visuals are visible only when they are added to a frame in that scene. An application can add a visual to a frame by using the IDirect3DRMFrame::AddVisual method. The frame provides the visual with position and orientation for rendering.
You should use the IDirect3DRMVisualArray interface to work with groups of visual objects; although there is a IDirect3DRMVisual COM interface, it has no methods.
The most common visual types are Direct3DRMMeshBuilder and Direct3DRMTexture objects.
