Motivation (cont.)
Chinese landscape paintings
Horizontal or vertical scrolls
from Mustard Seed Garden Painting Manual, revised version by Ch’ao Hsun, 1887

Multi-Perspective Modeling (MPM)
Solution: introduce local and global models; switch them smoothly
TIP is not applicable for multi-perspective images:
horizons at different levels multiple cavities
Sub-scene 1Sub-scene 1Sub-scene
2Sub-scene 2

MPM: Global Modeling
Global model
Rectangle Cylinder
Sphere

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