Alternatively, ' 'paper bag' ' icons can mark the position of polyhedra, revealing their size but not their shape. For simulations, the links of redundant robots are modeled by a union of line segments or convex polyhedra. Consequently, how to accurately model convex polyhedra is very important for efficient minimum separating distance computation and collision detection. This section introduces polyhedra and studies the problem of how many tetrahedra are needed to mesh them. Two-dimensional polygons and threedimensional polyhedra (curved or linear) are widely recognized examples of solids. In fact the problem of calculating the closure of the convex hull of two polyhedra is also exponential even for bounded polyhedra (polytopes). According to the different intersection situations, we can understand the emergency about the current status of those dynamic polyhedra. Direct construction of the perspective projection aspect graph of convex polyhedra. In applications, parametric propagation can be used to find linear construction sequences for nonspherical polyhedra. For two polyhedra have l and m facets, respectively, polyhedral approaches need l*m operations to determine the closest facets for computing the minimum distance. Interestingly, there are polyhedra whose tetrahedrizations have necessarily more vertices than the polyhedra. This section introduces both concepts and shows how they can be obtained as pro jections of the boundary of convex polyhedra. This allows us to relate the symmetry groups of two polyhedra, the original and the derived zonotope. These examples are from corpora and from sources on the web.
