While putting to practice everything I've learned in this meanwhile regarding art restoration/enhancement I've got this one so destroyed due to consecutive JPEG compressions from multiple sources that I just can't save the background.

But before I can replace it I must ask how could I reproduce this polygon:

enter image description here

It has some pseudo-3D appearance with 3 distinct colours, inside, outside and the borders. The shape appears 4 times in the picture, at different parts (you can see a blue shine of a second instance close to this brownish-orange one) and with different positions, so I must be able to adjust this... extrusion? E.g: the blue one nearby has both the "hole" and the darker area turned right, down inclined. Theoretically, I believe it should suffice to duplicate and rotate, but who knows...

Additionally, it also has this spiky shine behind with two distinct colours with a tiny fade when they change. If they could emit light over the main image — which I already finished the stressful selection (so many curves... >.<) — it would be awesome, but not entirely required.

Problem is I have no idea how could I do that. In past, I had very bad experiences with Photoshop's way of dealing with shapes. Back in the day, I had to make the shape with the correct dimensions right at the first try because the edges became blurry after Free Transforming.

Of course, that certainly was just me knowing less than I know today but, in any event, I thought for the best to ask first how could I do that.

Thank you for your time

  • Can we see the other shapes? Perhaps it's not worth doing it in 3D, depending on how the others look like – Luciano Jun 11 '18 at 16:00
  • They're all the same, only changing colours and rotation – Bruno Augusto Jun 12 '18 at 10:46

I know you asked for Photoshop, but in my opinion it would be much easier in to create such a pseudo-3D shape in Adobe Illustrator, by using its Live Paint functionality.

It's easier because all you need to do is draw lines with strokes - using the raster image to trace over the top. Closed shapes aren't required. Also, there's no messing around with shape layers like in Photoshop.

Then you can turn it into a Live Paint object. And fill the segments using the Live Paint Bucket, holding down Alt to sample the colours from the raster image with the eyedropper.

Example - here I'm halfway through colouring it.

enter image description here

When you have finished you can change the stroke colour or remove the stroke entirely.

The beauty of this is that it's all vector. You can even place the finished AI in Photoshop, and when you resize it will not suffer from quality degradation.

enter image description here

Another possibility is to make a 3d extrusion in Illustrator, using a heptagon, with a thick stroke.

enter image description here

Then Expand the Appearance, ungroup, and fill the different segments with the required colours. Finish by drawing a blue shape and send to the bottom of the stack, then add additional paths for the inside corners, and fill as required.

enter image description here

  • Sigh... I give up. Could you detail the second step some more? I never used Illustrator before so, even though I found out that "3D Extrusion" is a Filter and that "Expand the Appearance" means "click the three dots (:P), I couldn't continue after that. – Bruno Augusto Jun 13 '18 at 19:58
  • And since this seems this second example will allow me to create shapes with the correct proportions, what do I do after that? Just open the file within Photoshop? Also, I have the feeling that I'll have to repeat the process again and again for each rotation, right? Because the... "inner walls" disappear every change I make to the angles, but they return as soon as I change a little bit the Perspective. – Bruno Augusto Jun 13 '18 at 19:58
  • @BrunoAugusto To expand click Object > Expand Appearance. Yes, you can import AI files into Photoshop as a Smart Object. Not sure what you mean about the inner walls disappearing. If you mean you can't see them distinctly, it dosn't really matter, as they are still there. I added a second light source in the 3d extrude just to make them more visible. – Billy Kerr Jun 14 '18 at 7:04
  • @BrunoAugusto After you have expanded, click Edit > Ungroup repeatedly until there are no more groups left to ungroup (the option will become greyed out).. To fill a shape, select it using the Selection Tool (V), and change the fill attribute in the tool bar along the top. – Billy Kerr Jun 14 '18 at 7:16
  • Right... I somehow managed to get closer to yours, except yours is deeper, apparently, because of the Extrusion Depth, even though I set it to 60pt like your image. Now I need help with the internal lines because it seems I need to delimit their rectangular area to pain/fill only inside them, without bleed to the closest "interior wall". Last but not least, I think I managed to get what the inner shape would do by hiding its layer (which was blocking my way to fill the interior, that's why I said they were disappearing) – Bruno Augusto Jun 15 '18 at 11:38
