| Summary: | One of the mostly researched areas in computer graphic is wet cloth simulation. Where, there are many factors affecting cloth simulation. Among the challenges in simulating cloth is taking into consideration all these factors for example, wetting, internal and external forces. Thus, this study aims to achieve high realism wet cloth simulation, and take in consideration the forces that may affect the process of simulation. Mass Spring Model is the technique that proposed to simulate the wet cloth under the forces of wind and gravity. Initially, to produce the cloth sheet, a cloth structure is being constructed from a matrix of mass point connected by springs. Then, external and internal forces were applied on the cloth sheet. The internal forces represent the tension between the springs in forming the cloth particles. External forces are represented by wind and gravity. Next, wetting process is applied on the fabric particles. In wetting process, cloth absorbed a substantial amount of fluid which will then affect the physical properties and appearance. In the experiment, the amount of absorbed fluid is calculated using absorption equation, with increasing values of variable up to saturation level. It was observed that there are changes on cloth texture as the wetting increased. The color of cloth texture became darker with increasing wetting value. Highest concentration of texture color can be observed as the cloth reached the saturation level. Finally, wet cloth is being compared with dry cloth in terms of color, physical behavior and motion. The cloth has all the properties of wet cloth like in the real life where, it is appear heavier, darker color, appearance and physical behavior. Future work for this study suggests many prospective works especially, simulating the real interaction between the fluid and the cloth. |
