Hey Nooop triangle caching occurs when an object is static in a scene ie it doesn't move and the camera viewing it doesn't move. in such scenarios, redrawing triangles would occur in exactly the same way, so when it is possible, Away3D skips that step.
occlusion culling is something entirely different and not carried out at all by the engine. hth!
