Computes the global properties of a solid region of 3D space which can be delimited by the surface and point or surface and plane. Surface can be closed. The method is quick and its precision is enough for many cases of analytical surfaces. Nonadaptive 2D Gauss integration with predefined numbers of Gauss points is used. Numbers of points depend on types of surfaces and curves. Error of the computation is not calculated. More...
