26 /** \class TEveQuadSet
27 \ingroup TEve
28 Supports various internal formats that result in rendering of a
29 set of planar (lines, rectangles, hexagons with shared normal) objects.
30 
31 Names of internal structures and their variables use A, B and C as
32 names for coordinate value-holders. Typical assignment is A->X,
33 B->Y, C->Z but each render mode can override this convention and
34 impose y or x as a fixed (third or C) coordinate. Alphabetic order
35 is obeyed in this correspondence.
36 
37 For quad modes the deltas are expected to be positive.
38 For line modes negative deltas are ok.
