Description

The GPU Technology Conference is the most significant event in 2009 dedicated to application development on the GPU. Encompassing three simultaneous summits, this event will focus on the latest breakthroughs developers, engineers, and researchers are achieving through the use of the graphics processing unit (GPU) to solve the world’s most important computing challenges.

OptiTex Virtual Try On Engine

Imagine what having: Realistic CG clothes so convincing, they could not be distinguished from pictures. Real time rendering capabilities of human bodies and faces that reproduce incredibly realistic results. Images of clothes that portray fit, feel and look with high fidelity. … Would do to online apparel
