Reading: "Artistic Multiprojection Rendering"

Absract

• Introduce a tool for creating such multiprojection images and animations
  • a multiprojection rendering algorithm
  • an interactive interface for attaching local cameras to the scene geometry

• The most common method for creating a multiprojection image requires a combination of 3D rendering and 2D image compositing.

Contribution

• propose an algorithm that automatically resolves visibility for most practical cases and allows user adjustments when the automatically computed visibility is not satisfactory
• simple and intuitive set of camera constraints allowing the user to choose appropriate projections for a variety of artistic effects
• leverage multipass hardware rendering to achieve interactive rendering

Strength and Weakness

• adequately addresses the problem of resolving visibility in the multiprojection setting
• use a master camera to specify visibility ordering while maintaining shape distortions due to local cameras attached to each object
• provide several novel camera constraints that allow the user to obtain commonly desired effects with relative ease
• In certain cases, occlusion cycles can pose a problem in determining visibility ordering in an image
• difficulty in dealing with lighting effects

Ideas for Extention

• This system seems very suitable for architecture design. Drawings such as multi-sectional views on a single page and a large building are good examples for which users can utilize this system.

Open Questions

• What other uses can we think other than artistic expression, representation, and visualization?
