1. Garment represented as a mesh

A mesh is a group of triangles connected to each other by shared vertices that define the surface of a cloth piece in OptiTex 3D cloth simulations.
Triangles are incapable of accurately representing curved surfaces, so a larger number of them must be used to approximate curved lines, folds and wrinkles in a visually appealing manner. The number of triangles composing the mesh is defined by the Resolution field in the 3D Properties window. Increasing the 'Resolution' of a piece actually means reducing the lengths of the triangle's edges and thus increasing the number of triangles which compose the mesh.
Using high resolution cloth panels severely effects simulation performance (speed), so use this control wisely meaning small pieces or pieces that should reveal folded details should have a low resolution value whereas large, generally flat pieces need not be simulated with thousands of triangles.
You can view cloth pieces as meshes by selecting the 3D menu and then Show Springs.
In the following example (images no. 2-5) you can view the difference between low and high resolution when simulating pieces with curved lines.
