Photoshop and Perspective Help

[xenogia]

Hey Guys,

I'm trying to add a desk of some sort to this room for an evidence room in my game.  But I am having trouble trying to find a desk and getting the perspective right.  Any ideas or help would be greatly appreciated, I'm not fantastic at this.

This is about the right perspective.

By drawing the perspective lines(red), you can find where the perspective points are, and use them to draw the table (green).

All you have to do now is to take your camera, and take a pic of your table (or any table that you think will fit in) in the right perspective.

Two important things to notice are that you need to adjust the light direction and shading of your pic, so they match the background picture (else the table will look bad, compared to the background) , and try to take as big a pic as you can, so you can scale the table to the background. (better scale down, than up)

But how will you make just the exact perspective on the pic? Hahahah, I don't have a clue!

The second option is to render it in some photo-realistic 3d renderer, so you can adjust the size and perspective there.

Thanks Jim.. this helps immensly.

You've probably sorted this out already, but SketchUp has an option to match the perspective of a rendered scene to a photograph. If you haven't got SketchUp, it might not be worth the effort to download it and learn how to use it just so you can add a desk to this image.

Well he might use it for than just that photo/background.
The tool is actually for making 3d models from a photo and you do it by matching perspective, but I guess the process could be basically reversed.

Actually, Xen, can you tell me the size of the table you'd like and I'll it. There might be more of a problem with the lighting being kind of complex, so I can make you just a model, with textures and then you shade it. Also some mesaurments, like how high is that door or the size of one of those boxes, would help.

EDIT: here's a test (i'm learning as well ), pm if you have questions, no textures but you can handle that

here it is where I placed it: http://img.photobucket.com/albums/v320/aniantokin/matchphotodesk2.jpg
tell me if you want a different colour or texture (though warning, it'll look bad unless I render it but matching lights is a bit too much work), also pm a pic of where you want the table to be on the floor (point of 1 corner will do)
