There's something I've been always wondering about perspective assistant tools

I might not be the best to give an answer to this, but as all opinion could help :slight_smile:

  1. I think the problem is just that for users without any experience of perspective, it could be difficult to place assistant to get something that can make sense or that can help to guide you for what you have in head

  2. Set up is not hard, but it could need time and many essay before having something for which you’re satisfied with
    Example with my BuliKong, it took me time to define how to place the 3 vanishing points to get the result I had in my head; it was in an iterative phase: place 3 vp, draw some lines; erase, move vp, draw some lines, erase, move vp… until I got satisfied of perspective result

  3. My point of view is not “do we need” but more “how”, because preset for me means nothing, I’m sure that in 99.999% case a preset or a template can’t match to any of my needs; and providing 1, 2, 3, or more preset, you’ll always find someone that is not satisfied; one will need low-angle, another one high-angle, someone else want to be near to subject and me I want to be far from subject, wide focal length, short focal length, centered, left or right positioned, … ???
    There’s to many possibilities to be able to define what a “sane” perspective templates should be

What I understand with blender or firealpaca is you can easily from a cube, move your camera around the cube and define angle of view (I prefer “focal lenses” terms but not sure that it could be understood by non-photographer)
By moving around the cube (camera rotation, translation, roll, angle of view; cube size), you can have a better idea of what you’ll get, and easily define where vanishing point should be; in synthesis, a 3D cube let you:

  • Having a good idea of what perspective will be
  • Fast to check different configuration of perspective
  • Easy to set vanishing points

This solution is not perfect especially if you have a complex scene in mind but it could help.
And for really complex things, a dedicated tool like blender to help to determinate composition and vanishing point position might be the solution I suppose.
