We present various algorithms for antialiasing silhouette edges of manifold and non-manifold implicit surfaces. The algorithms are: object space, edge blur, super-sampling, adaptive pixel-tracing, and jitter-based antialiasing. We discuss the strengths and weaknesses of the approaches and compare the results. We also discuss the antialiasing of contours rendered on implicit surfaces. The algorithms for antialiasing and rendering contours take place in the GPU and so are performed in real time. This allows us, for instance, to animate contours on a surface in real time by changing contour parameters. We give examples showing the results of our antialiasing techniques for various types of contours rendered on surfaces.
