Summary: 

The following reference may be of interest to you. I am 
posting the abstract of  the papert too so that you can decide(depending
on your needs and interests) whether it is worth searching for.

Geometric Modelling : a survey by A. Baer, C. Eastman and M. Henrion.
Computer Aided Design volume 11 page 253-272.

"Computer programs are being developed to aid the design of
physical systems ranging from individual mechanical
parts to entire buildings or ships. These efforts highlight
the importance of computer models of three deminsional objects. 
Issues and alternatives in geometric modelling are discussed and 
illustratred with comparisons of 11 existing modelling systems,
in particular coherently- structured models of polyhedral solids 
where the faces may be either planar or curved. 4 catogories of 
representations are distinguished: data representations that store 
full, explicit shape information; definition languages with which 
the user can enter descriptions of shapes into the system and 
which can constitute procedural represenations; special 
subsets of the information produced by application programs; and
conceptual models that define the logical structure of the data
representation and/or definition language."
