    abstract     = "A volume sculpting system is presented.
The system provides tools for interactive editing of a voxel raster
that is stored in an octree data structure.
Two different modes of sculpting are supported: Sculpting by adding and
subtracting solids, and sculpting with tools that are based on a spray
can metaphor.
The possibility of extending the method to support multiresolution
sculpting is discussed."
