This paper describes VolDmi, an open system for volume modeling and vi
sualization defined as an interactive platform which will integrate cu
rrent and future research developments, as well as specific applicatio
ns. The article begins with the analysis of the main functional module
s of the system. Then, the design criteria which have been followed ar
e explained and the system's global operation is described, with speci
al emphasis on user interaction. Subsequently, the central kernel of t
he system is presented. This kernel is mainly composed of input/output
modules along with creation and operation modules for a generalized v
oxel-model. Finally, the default visualization of the voxel-model that
has been implemented in the system and which is based on the slice st
acking algorithm, is presented. Copyright (C) 1996 Elsevier Science Lt
