Spatial Editing for Interactive Inspection of Voxel Models
Voxel models are suitable for the representation of three dimensional objects of arbitrary topological complexity. They are mostly used for storing spatially sampled real-world data or data resulting from scientific simulation programs. In order to bring out the possibly highly irregular structure of the volume data, a visualization system for voxel-based objects should not only offer various (surface- or volume-) rendering methods, but also spatial editing operations.
We propose using an editing method, based on binary space partitioning. Construction of the binary space partitioning tree, that represents the subdivision of the voxel model, is done by interactive steering of the partitioning planes through the voxel model. The resulting BSP-tree is subsequently used in the rendering of the object. The advantage of a BSP-tree based partitioning is that it may be used in conjunction with many existing volume and surface rendering algorithms.
