Computer scientists at the University of California, San Diego, have developed a new model that simulates the lighting interactions on computers with unprecedented precision. New models of animated movies and video games can be used to make cloth look more realistic.
The existing model is too simple to produce unrealistic results, or the actual use is too complex and expensive. The researchers introduced their findings at the SIGGRAPH 2013 conference in Anaheim, California from July 21st to 25th.
"Not only is our model easy to use, it's also more powerful than existing models," said Iman Sadeghi, who worked on the development of a mode of work at the same time in his Ph.D., Department of Computer Science and Engineering at the University of California, San Diego. He is currently at Google in Los Angeles, after he received his doctoral degree in 2011.
Dr. Sadeghi said: "This model solves the long-standing problem of making cloth" Henrik consultant Van Jensen, who won the Academy Award, brought in the 2004 animated character skin that was later used in the study. Many Hollywood block saboteurs include the Lord of the Rings. Cloths in movies and games often look wrong, and this pattern is the first practical way to control the realistic appearance of most types of cloth.
The model is based on a new method to simulate the interaction of light by simulating how each light thread scatters each thread. The model then uses this information based on the weave pattern of the fabric. It is essentially the same way that the fabric is meshed with the hair of the microcylinders that scatter the light, but in a 90-degree angle to each other," said Sadeghi.
Sadeghi simulates the theme of hair interacting with light is an expert. Although Dr. Jensen's research group of students, he developed a model, which was only later in Disney's "tangled," retelling of the Grimm Brothers Fairytale Rapunzel. The protagonist of the animated film sports a 70-foot model of blonde hair.
In SIGGRAPH paper, the author also simulates other types like pure linen fabrics and silk twins. Their goal is to demonstrate the processing power of different types of threads in the model and an infinite variety of weaving patterns. The only other model may be able to develop Sadeghi and his colleagues to put fabrics through a micro-CT scan, an expensive and time-consuming process to produce similar results. The work of other computer scientists is the measuring fabric of master student Joachim Deken.
