16 MPM: Sub-scene Modeling Local model for a sub-scene A box model as in TIP Foreground objects as “billboards”

17 MPM: System Overview Rendering Record animation key- frames Render & output animation Generate smooth camera path Modeling Build billboards for foreground objects from mask Model back- ground using TIP interface Select a global model Pre-processing Prepare: Foreground mask Background image Digitize the input image Identify sub-scenes For each sub-scene

18 MPM: Model Switching Scene entry points
