Please take a look at the attached image.
In it i have a subdivided plane. I also have the “show overlays” button enabled.
So i’m getting a black grid with little dots at each vertices.
Ok, so this stuff is meant as a visual aide. But imagine i actually want this sort of stuff to appear in my render? Is that possible? The key point is that perspective has no effect on these elements. They follow the lines of perspective but remain flat with a constant scale. So i imagine that would be the tricky part. For example, creating lines in your viewport that recede into the distance, but keep a constant width.
Any ideas on this? I should explain i’m using Blender for graphic design / 3D arty stuff, i’m not trying to create realistic images!
