Has anyone written a standard 3-D program using X-Windows to draw a number of polygons, one on top of the other, so that the ones at the back are hidden (or partly hidden) by the ones at the front ? I would appreciate being sent the source code if you have such a program. The type of input data I need to plot (for eg.) is :- x = 1 y = 12 z = 1 x = 2 y = 10 z = 1 x = 3 y = 9 z = 1 x = 1 y = 15 z = 2 x = 2 y = 6 z = 2 x = 3 y = 12 z = 2 In this eg. there are just two polygons ( z = 1, z = 2 ). Note x values range from 1 to 3 in each case while the y values are varied. The polygon z = 2 should be plotted in front of the other polygon. John Freyer -- John Freyer freyer@prl.philips.co.uk
