We discuss the polygonisation and rendering of non- -manifold implicit surfaces using adaptive octree subdivision and interval arithmetic for surface exclusion in octree nodes. We present a new algorithm that polygonises ...

We present a point based rendering technique that uses iterated function systems to render arbitrary parametric and implicit surfaces with singularities and non manifold features, to the pixel precision of the image. ...

We present point based rendering techniques that render various types of contours as constant width slabs on surfaces. The techniques requires evaluations of the surface functions and gradients to render shaded images. ...
