I'm looking for a function that lets me take a rectangular face viewed from an oblique angle, and square it up as if I were looking straight at it.
For example (sorry, can't draw pictures to show you what I mean), suppose I take a photo of an apartment building while I'm standing across the street and off to one side. I need a tool that lets me click on the four corners of the building's face and un-distorts the face, making it rectangular.
I have used a non-PDN tool (GIMP? Photoshop?) that had this capability. We used it to model the buildings at http://ray.datech-ne...TI_Gallery.html from actual photos.
Now I'd like to do this with PDN. I read about Evan Olds' Quadrilateral Reshaping and dpy's Perspective Effect. I've installed both plug-ins, and while they can do the trick with a little nudging, they're not exactly what I'm looking for.
