Flat structure, perspective correction

    Maybe that thread should go into the card models section, but it's model railroading related.
    I grabbed a warehouse building structure on the web ( sorry, I can't remember where )
    I used "The Gimp" to correct the perspective so maybe I could get a low relief structure out of it.
    Here are the pictures before and after.

    Looks like that will work just fine!

    Another idea is to tweak the templates of the N scale modular structures from Walthers and add some doors and windows + the brick color to them.

    I think the correction looks good, but needs a bit more work. However, I don't know what that entails, so I can't say if it will be easier than the modular approach.

    The main wall looks good, but the illusion of it being a "head on view" is spoiled by the rooftop structure, the large mechanical unit in front on the ground, and the large door behind the railing. All three retain a significant "third dimension". I don't know if you can correct those parts individually, but it might be worth a try.

    Hope that helps.

    Looks like you corrected the perspective well! :thumb:

    No problem, those three issues could be remedied in about 10 minutes with any decent graphics application.

    What I would worry about instead is the apparent low resolution of the original image (if the posted JPG is any indication). A higher resolution image will have more detail and produce much better results, even at N scale. If you are modeling at HO scale, I would suggest working from your own photography, so you can get a higher resolution original image.

    Thanks for the additional info Art.

    I suppose I should have said "retain a significant third dimension which doesn't match the rest of the corrected perspective", since the stated objective is to get a low relief structure.

    I agree with you Andrew, some parts mostly the rooftop structure spoils the" head on view".

    Thanks to drop by on the model railroad forum and give your suggestions Art Decko. I know you are a frequent ( and well respected ) poster on the Card Models forum. I agree, the picture resolution is not very good. I just downloaded that pic from the internet because it is a very typical structure of a railroad in an urban environment.
    I found the Walthers template interesting because it gives the right N scale proportions of industrial structures.

    My goal is to make a low relief structure in that style:

    But maybe the simplest solution for me would be to buy some Walthrs Cornerstone Modulars components.

    As mentioned the perspective of the bottom part of the building looks good, the top not so much. Although I'm not sure how the program you're using works, maybe the solution is to print what you have, cut off the top part, then do another image where you correct the perspective only for that top part and print it separately. Then assemble them together.

    As for Walther's modulars, I really like them. They fit together perfectly and the flexibility they give you is great!

    I sometimes take a kit and "flatten" it out, using the front and back side by side to make a background flat. That's another option.

    Personally, I think the best approach is a mix of techniques. Fully modelled buildings in the foreground, low relief structures against the backdrop, and photos on the backdrop.

    Actually, for me the perspective on the roof cabin looks OK; you just need to carve off the side wall.
    For the amount of work involved, it should look respectable.
