combinatorial maps造句

例句与造句

1. An " n "-dimensional combinatorial map represents the subdivision of a closed orientable " n "-dimensional space.
2. The last line of this definition fixes constraints which guarantee the topological validity of the represented object : a combinatorial map represents a quasi-manifold subdivision.
3. So, there are two ways to represent a combinatorial map depending if the permutation is " ? " or " ? " ( see example below ).
4. When all the represented cells are simplexes, a simplicial complex can be used, but when we want to represent any type of cells, we need to use cellular topological model, like combinatorial maps or generalized maps.
5. Like combinatorial maps, generalized maps are used as efficient data structure in image representation and processing, in geometrical modeling, they are related to simplicial set and to combinatorial topology, and this is a boundary representation model ( B-rep or BREP ), i . e . it represents object by its boundaries.
6. It's difficult to find combinatorial maps in a sentence. 用combinatorial maps造句挺难的
