We present a new method
for rendering silhouettes of point-based models. Due to the lack of connectivity
information, most existing polygon-based silhouette generation algorithms
cannot be applied to point-based models. Our method not only bypasses
this connectivity requirement, but also accommodates point-based models
with sparse non-uniform sampling and inaccurate/no normal information.
Like conventional point-based rendering, we render a model in two passes.
The points are rendered as enlarged opaque disks in the first pass to
obtain a visibility mask, while being rendered as regular size splats/disks
in the second pass. In this way, edges are automatically depicted at depth
discontinuities, usually at the silhouette boundaries. The silhouette
color is the disk color used in the first pass rendering. The silhouette
thickness can be controlled by changing the disk size difference between
two passes. |
