Pants Geometry

The pants are cut off using Planar patches whose structure achieves softer and more organic results. The part for the belt is placed around the waist using a bend SOP. The belt-carrying ring is made from a square and is positioned so that it is connected to the part where the loop is supposed to be.

If the Attach node is inserted to secure the part for the belt at the waist before the drape, the waist part will drop down to the floor, and the clothes will bump against the body and bounce up. Here are simulations of when an Attach node is inserted and not inserted. 

          with attached
      pants fall down and looks bad, you will be cold and naked.

                                      without attached
                                                                   Your pants stay on and you don't look foolish.             


Pants Simulation

If you use a vellum solver, the part that you connected using a Stitch node when you made the pants geometry will fall back. You can connect this part again using Stitch node.

For the pants simulation, I gave a high stretch stiffness and compression stiffness. Bend stiffness is set at 0.7.

If you look for the right figures for jeans, you will often find them looking like leather or rubber. This can be done by modifying Mass, Thickness, Street Stiffness, Compression Stiffness and Bend Stiffness. This figure is not the answer because jeans vary in thickness, lightness, and style.

The images below show how simulation changes as each value changes.

<stretch stiffness=1e+5>  <bend stiffness=0.0007> <compression stiffness=10000> <thickness = unchanged>                 <mass=0.001>                               <orginal> 

Simulation Detail

The details of the wrinkles will be insufficient when the pants start to walk. To fix this, different numbers should be added to areas with zippers and to areas with different thicknesses of clothing. It is convenient to assign groups to this part when making pants.

The photos below show how wrinkles change as you add details.

                                <add nothing>                                  <add another figure to the belt part>          <add more bend stiffness in back>         <add bend stiffness in thick part>

    Hi, I'm curious how you made attaching groups and targeted groups of trousers.
