What Is Cloth Modeling?
Cloth modeling is a form of 3D modeling that allows computer graphics programs to create the appearance of clothing on 3D models, or fabrics within the programs. It is a crucial part in creating organic items such as clothing for 3D models created to appear human, or items within the home, or within the interior of a vehicle.
How is the appearance of cloth created within the 3D models? There are various types of mesh that will create the appearance of cloth. The main three types of meshes that are used to create the appearance of cloth are: geometrical methods, physical methods and particle/energy methods.
The appearance of cloth can be created through the use of geometrical methods, which are adequate in using curved lines to create the appearance of the texture of cloth. One of the primitive methods, using geometry to create cloth works well on cloth items that require single framing, which gives the object structure.
Physical methods of cloth modeling use a grid of particles which are linked together through springs. Tension, stiffness and weight are the three combined aspects to create the cloth appearance. There are three terms which are included in this technique: s terms, b terms and g terms. S terms will define the elasticity of the object, b terms will define the blending of the object, and g terms will define the gravity of the item. Aspects such as stiffening of the fabric, or stretching, and shearing of the fabric can all be defined through tweaking the certain ratios.
Energy and particle methods are used to create the illusion of cloth in complex structures by using energy rather than springs to connect the cloth. One of the main benefits of creating cloth through energy and particle is the prediction of how the cloth will react in any given circumstances.
Using these techniques, modelers are able to create valid, lifelike models that can be attributed to creating cloth that appears silken, wooly or even the traditional cotton.
