The Extreme Vertices Model (EVM) has been presented as a concise and
complete model for representing orthogonal pseudo-polyhedra (OPP) in
the solid modeling field. This model exploits the simplicity of its
domain by allowing robust and simple implementations. In this paper
we use the EVM to represent and process images and volume data sets.
We will prove that the EVM works as an efficient scheme of
representation for binary volume data sets as well as a powerful
block-form surface renderer which avoids the redundancy of
primitives on the extracted isosurface. In addition, to achieve more
realism, the normal vectors computed by gradient of grey-level from
the input data can be added to the model. Furthermore, an
efficient tessellator of non-convex orthogonal faces is presented.
Also, useful operating and manipulating tools
can be implemented over the EVM, like editing operations via Boolean
operators, non voxel-based morphological operations and an improved
connected component labeling algorithm. The well-composedness
property of the volume can be detected easily as well as the
critical zones where the non-manifold configuration occurs. |
