Currently the vanishing point assistant let you place vanishing points wherever you want irrespective of one another’s positions, which can lead to highly inaccurate placements where you have 3 main vanishing point in which the triangle that they form have an angle larger than 90 degrees, which is physically impossible. The vanishing point assistant also lacks the ability to determining how far each vanishing points should be from the center of view according to the FOV of your choosing, and maintain a consistent FOV between multiple sets of vanishing points. Currently if you want to set up vanishing points according to a specific FOV, you either have to calculate them manually using trigonometry, or use a 3D program like blender to render out a cube using a specific FOV (or focal length), save it as an image, then import the image into krita, and manually align all 6 vanishing points (3 main, 3 diagonal if you want to create a 3d grid) to the rendered cube, and then if you want to rotate the perspective, you have to rotate the cube in blender, and then repeat the previous steps all over again.
It will be revolutionary if all of this can be done automatically, and that’s the feature request: create a 3d based perspective assistant generator that can let you rotate your perspective just like in blender while generating all 6 vanishing points of the perspective automatically, and give you the ability to set the FOV(or focal lengths based on camera standards) of the view of your canvas while having the vanishing points scale automatically depending on the FOV.
