Combining implicit surfaces with soft blending in a CSG tree

Abstract

In this paper, we show an extension of the model proposed by Sabourdy, combining various implicit surfaces with soft blending capacities in a CSG tree. This extension allows integration of plane surfaces, skeletons and many other types of implicit surfaces. It particularly develops the blending possibilities offered by this approach. The model is then able to generate a wide variety of shapes on which the user may act through a limited number of parameters.
