Summary: Artistic Multiprojection Rendering
New York University
In composing hand-drawn images of 3D scenes, artists often alter the projection for each object
in the scene independently, thereby generating multiprojection images. We present a tool for
creating such multiprojection images and animations, consisting of two parts: a multiprojection
rendering algorithm and an interactive interface for attaching local cameras to the scene geometry.
We describe a new set of techniques for resolving visibility between geometry rendered with
different local cameras. We also develop several camera constraints that are useful when initially
setting local camera parameters and when animating the scene. We demonstrate applications of
our methods for generating a variety of artistic effects in still images and in animations.
In computer graphics we typically use a single linear projection often a perspective projection
to generate a realistic view of a scene. Linear projections achieve this realism at the cost of
imposing restrictions on the 2D shape of each object in the image and on the overall composition
