ABSTRACT
We introduce ShadowAstro, a system that uses the levitating particles’ casted shadow to produce a constellation pattern. In contrast to the traditional approach of making astronomical observations via AR, planetarium, and computer screens, we intend to use the shadows created by each levitated bead to construct the silhouette of constellations - a natural geometrical pattern that can be represented by a set of particles. In this proposal, we show that ShadowAstro can help users inspect the 12 constellations on the ecliptic plane and augment users’ experience with a projector that will serve as the light source. Through this, we draw a future vision, where ShadowAstro can serve as an interactive tool with educational purposes or an art installation in museum. We believe the concept of designing interactions between the levitated objects and their casted shadows will provide a brand new experience to end user.

Shadow silhouette maps
The most popular techniques for interactive rendering of hard shadows are shadow maps and shadow volumes. Shadow maps work well in regions that are completely in light or in shadow but result in objectionable artifacts near shadow boundaries. In ...

Silhouette clipping
SIGGRAPH '00: Proceedings of the 27th annual conference on Computer graphics and interactive techniquesApproximating detailed with coarse, texture-mapped meshes results in polygonal silhouettes. To eliminate this artifact, we introduce silhouette clipping, a framework for efficiently clipping the rendering of coarse geometry to the exact silhouette of ...
