Param-o of an detailled wall-elment with rotated bricks.
The bricks are cut by intersection with a bounding box so that the
object remains stretchable in 2d and 3d.
Animation of train steamtrain in landscape. Animation controlled by
global parameter (current frame number). All objects (train, landscape,
trees,..) are only made with param-o primitives. Different sequences are
edited in video-software.
