Abstract
Recently an automatic solution to the problem of applying 2D textures to an
implicit surface has been introduced (13). The method derives a uv-texture
coordinate system by tracing particles from the implicit surface to a \fIsupport
surface\fR. In this paper, we describe the adaptation of this algorithm to the
\fIBlobTree\fR data structure. The \fIBlobTree\fR provides an implicit modelling system
through a hierarchy of blends, CSG and warping applied to primitives. There
are several problems involved in applying textures in such a general modelling
system, particularly across CSG junctions. In this paper we identify these
problems and introduce some simple solutions.
