Hi,
ok.
Principle of distort tool failing here, In Pshop, the gap between railings diminishes with distance , as in a real photo of railings.
HOWEVER doing a quick test, the gap remains same using this CageEdit method.
It should diminish with distance, as in the photoshop treatment of the same shape.
(I established with a pic of railings many years ago that photoshop distort tool recreated the logarithmic gap diminishing pattern), their perspective tool doesnt but distort tool does :-), great for such tasks, even undistorting a photograph of a plan etc !
see attached.
the darker red lines are where pshop correctly puts the wheel and box relationship lines, not the same gap at near and far that cageEdit created for the further stretched ‘red’ test…
I am trying to establish the gap between wheel and box when seen in perspective. I need to predict in a perspective photo where the box comes to as I can only se the nearside and offfside tyre edges. I have my vanishing lines traced on the photo to show near and far wheels as they are, then created a target shape to match my shape to and in absence of DistortTool use the suggested CageEdit method Rectangle, U 2 V 2.
so CageEdit is failing in this concept.
How does one create the logarithmic perspective true mathematical effect of Pshops distort tool ?
I need to do so for this wheel/box picture match. In the ortho side view I need to see the nearside and farside box edges.
