The first stereolithographic 3D printer was invented in 1987 by Chuck Hall. At the time,The Albert Consulting Group for 3D Systemswas figuring out how to transfer the data about the models to the printer. Using tessellation ended up being their choice. The solution was to tessellate the surfac...

C++标准24章有一个小节叫“Sorting and related operations”。它包含了很多对已序区间进行的操作,和三个排序用泛型算法:sort(),stable_sort(),和partial_sort()。 前两个,sort()和stable_sort(),本质上有相同的接口:同通常的STL泛型算法一样,传入指明了需要排序的区间的Random Access Iterator。 同样,作为可选...

standard sequence containers (array,vectoranddeque), lists perform generally better in inserting, extracting and moving elements in any position within the container for which an iterator has already been obtained, and therefore also in algorithms that make intensive use of these, like sorting ...
