About generate legging mock-up from pattern

[romeo1]

Hello,
I'm doing a project that must generate to a legging mock-up from fabric pattern.
As you can see, this is the fabric pattern of right leg:
From this fabric pattern, we will sew and make the legging

My question is, how to generate the design from fabric pattern to legging mock-up like this? Or any technology, function in Imagemagick can do that?
Thanks,
P/s: I attached all of design resources for your testing

If you had a 3D model, the task would be simple; see Painting people.

But you don't have a 3D model. You have only patterned fabric, and how that pattern looks when wrapped around a leg and viewed from four angles.

The pattern has solid colours, so you don't have data that defines which part of the fabric goes on which part of the leg. (If you did have that data, we could make displacement maps that could be applied to any fabric.)
