I need to make bump-map for objects like shirts or sofa that I could apply new patterns to it so how should convert the following shirt
? How can I make bump-map for this? Thanks
Photoshop has a great filter doing the job called displacement here you can find a pretty good tutorial how to apply any design on any "folds" please follow the link
The images that you show give an example of the exact opposite of what you're asking for. Its easy to apply a pattern or color onto a photo of a blank peace of cloth, but very complicated to remove it. I'd say its defenitely not worth the effort. Also because i can't see any reason why you would have to use that exact shirt.
I recommend mockups. You can find them all over the web (mostly free) like here for example:
Of course, a mockup for a Couch is a rather rare thing amongst the web, but for that i'd recommend just a photograph of a blank white couch like these and then apply your design or whatever you need to be on the cloth.
Hope that helps. Sry for bad english.
