I was wondering if photoshop or a plugin got a function, which can create a "plane" looking like pants and then fill it with the texture/pattern I want?
Something similar to vanishing point. Though in this case I got pants. So a square ain't useful.
Take a look at the pictures. I cut out the pants, make a plane looking thing, which shows the depths and folds in its area. After that I apply the texture/pattern. Is this possible with photoshop?
I hope you catch my meaning. If not I will try to describe myself better.
Read up on how to use the 3D tools, especialyl displacment texturing with the 3d postcard thingy...
Even without using the 3D features there are a couple of options (Warping, the Filter Displace, Liquify, Puppet Warp) that can be employed to simulate the spatial distorsions of the surface of the object, but I see no easy way to achieve the task if you really want the folds to be represented realistically.
