Polygon representation methods - Space Partitioning Representations
Space partitioning representations: this type of representation is used for explain the interior properties, through partitioning the spatial region having an object in a set of small non-overlapping contiguous solids i.e. usually cubes. Illustration: Octree that is the space partitioning explanation of 3-D object. For a better knowledge consider here figure 2.
Out of the different representational methods mentioned above, the most commonly utilized boundary representation mechanism for showing 3D objects is utilizing a set of polygon surfaces to enclose the object interior. Here discuss this mechanism in our next sub-section.
