Squaring up an oblique face

Recommended Posts

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.

Hello rrd,

The 2 plugins you mention are the best that I've found for this. Another way might be to select the face of the building with the lasso select and then use layers/rotate zoom and drag the globe icon around.

I'd be interested if others have more ideas too.

I know exactly what you really need, unfortunately PDN doesn't have this feature.

What you need actually is Google SketchUp, it is free but a little hard to learn, but fortunately this feature is so easy and direct in the program, you don't need higher skills for it.

Yellowman,

You're right; that's exactly what I'm looking for. Maybe one day PDN will have it. Until then, I guess I'll use SketchUp for that part of my work.

Rick has actually been very clear that PdN is not and will never be a 3d utility. It's just not made to be that sort of thing. :) It's not a failing, really. PdN is a pocketknife, it's used for a far different purpose than a machete is.

And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.
