Title:
- An Object Space Approach to Shadowing for Hair-shaped Objects

Abstract:
Three-dimensional objects can be rendered more realistically with their shadows. Commonly-used shadowing methods based on tex- tures with depth values are unfortunately likely to cause aliasing, which is usually ameliorated by such image-space post-processing as neighboring pixel averaging or variance-based smoothing. How- ever, spatial/temporal aliasing can still be observed in pieces and films of work when bundles of thin strands like human hairs are targeted. We can generate sharp shadows even from such intricate shapes if we suitably move their vertices or expand their mesh at the sacrifice of extra computation. Our method attempts to tackle this type of aliasing problem in a simpler manner by generating anti-aliased shadow splats in the object space.
