Gnomonic and stereographic transformations
Helliwell, J. R.  International Tables for Crystallography (2006). Vol. C, Section 2.2.1.5, p. 29 [ doi:10.1107/97809553602060000577 ]
Gnomonic and stereographic transformations 2.2.1.5. Gnomonic and stereographic transformations A useful means of transformation of the flat-film Laue pattern is the gnomonic projection. This converts the pattern of spots lying on curved arcs to points lying on straight lines. The stereographic projection is also used. Fig. 2.2.1.5 shows the graphical ...
