Problem: I plot a picture of spheres, spirals, sticks,... by Plot_on - Plot_off command. The picture is fine on the screen but the final PostScript is wrong: the intersections between balls - sticks - spiral are wrong. The invisible parts are visible and visible are invisible. I tried o versions 5.10.2 and 5.10.3, 4d_oplot versions 1.9, 1.11, 1.12 (with and witout 4d_odledit in the middle), and the latest oplot_1.15. All but oplot_1.15 work and produce the same Postscript output (without 4d_odledit). oplot_1.15 shrinks the picture into one dot.
The machine is
1 150 MHZ IP22 Processor FPU: MIPS R4010 Floating Point Chip Revision: 0.0 CPU: MIPS R4400 Processor Chip Revision: 5.0 Data cache size: 16 Kbytes Instruction cache size: 16 Kbytes Secondary unified instruction/data cache size: 1 Mbyte Main memory size: 96 Mbytes
Question: is it a mismatch between versions of o and oplot, or what? Which pair is working and how to get it? I got oplot_1.15 and it did not want to compile, some of the variables were defined twice - probably, I have messed it up removing the definition that is never used in the sub?

Could it be that you are trying to plot smooth objects? You need to change the setup so that you get solid objects (I think). These objects will then be made out of small polygons which are drawable on hard copy. I mean by objects the ball and stick figures not the object as in obj_name.

Yes, everything is very 'solid', otherwise there is nothing in the *.plt file at all...
