Is it possible to extrude a PNG image in Blender? (Perhaps using animation nodes or sverchok?) If Blender can read the alpha, wouldn't it also be possible to draw curves along the edges? (assuming the alpha is completely transparent or completely opaque, (I tried to do this in sverchok but couldn't work it out as I'm completely new to it.)

  • $\begingroup$ I think you'd have more luck converting it to a vector image (e.g., Trace Bitmap in Inkscape) before you import to Blender $\endgroup$ – ajwood Nov 20 '17 at 3:43
  • $\begingroup$ True, just thinking... if Blender already has the alpha edges data, it would be cool if it could then natively draw and extrude the edges. $\endgroup$ – Dan Nov 20 '17 at 3:55

    $\begingroup$ blender.stackexchange.com/questions/94602/… I'm not quite sure about what you want to do but if it is to "extrude picture depending on it's value" (or alpha or whatever) I think this post would help. $\endgroup$ – Allosteric Nov 20 '17 at 6:40
  • $\begingroup$ Using the alpha information on a displace modifier... or use it to feed the displacement socket on a material... $\endgroup$ – cegaton Nov 20 '17 at 6:48
  • $\begingroup$ Interesting, I haven't used that modifier before $\endgroup$ – Dan Nov 20 '17 at 9:51
