I have tried some minimally invasive changes to view2D and view3D spad files in order to intercept the graphics data before sending to viewman. Basically one has to modify "makeViewportxD", x=2,3, such that "makeViewportxD0" is called only if "viewman" is set as the frontend (default, of course). Particularly with regard to other UI it seems to me that introducing new plot functions is not a good idea. Preferably one should be able to use all "draw" function as usual, only by choosing another frontend. The following test file https://github.com/nilqed/sixelSPAD/blob/master/src/test_draw.input produced the output https://nilqed.github.io/drawfe/ (thumbs).
All draw functions but one seem to work properly: draw(curve(5*cos(t), 5*sin(t),t), t=-12..12) complained "no mesh" (not surprising). So my question is *how to extract 3d curve data from ThreeSpace (SPACE3)?* I've tried some of the functions there but got weird output. I have cribbed the methods "pointList" and "mesh" from gnuDraw (which is ok but a stopgap solution to me; draw is much more powerful, of course). -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
