28 //! This class is used to handle polyline selection. The main principle of polyline selection
29 //! algorithm is to split the polygon defined by polyline onto triangles. Than each of
30 //! them is considered as a base for triangular frustum building. In other
31 //! words, each triangle vertiex will be projected from 2d screen space to 3d world space
32 //! onto near and far view frustum planes. Thus, the projected triangles make up the bases of
33 //! selecting frustum. When the set of such frustums is created, the function determining
34 //! selection iterates through triangular frustum set and searches for overlap with any
35 //! frustum.
