2009 OptiTex At ECS

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

Virtual vs. Real

About OptiTex Ltd.
OptiTex is a developer of CAD solutions for the fashion and other sewing based industries
OptiTex has over 20 years of experience and more than 23,000 active installations worldwide.

Virtual try on Market
The potential
Apparel sales forecast will reach $40 billion by 2010 in USA alone.
Online clothing is showing the highest e-commerce growth rate (25%).
The challenge
Buyers cannot validate fit
Return rates are high (40%)
Existing Online catalogues are limited to predefined combinations
Poor shopping experience

The Solution
Required components
Real-time components:
Accurate, real time physics simulator
Photo realistic rendering capabilities
Synthesis of human body shapes
Virtual try on web application
Ecommerce platform
Off line components:
Advanced content creation tools
Ecommerce backend
Develop a virtual try-on engine capable of serving any apparel related E-commerce web site.

Physics
Cloth is modeled with a discrete set of final elements.
Each element models real forces such as:
Fabric weight
Stretch resistance
Bending resistance
External forces such as gravity, friction and wind
Newtonian physics are the governing equations
Iterative numerical methods are used to solve

Real Time Physics
Complex clothing items are modeled with more than 100K polygons.
50K vertices with 150K variables
For real time, the entire process is computed at 60 frames per second which translates to 16.6 Milliseconds per frame.

Accelerating Physics
Simulation bottle necks
Implicit integration and linear system solver
Collision detection
Normal calculations
Skin & Rig calculations
Rendering
Highly parallel nature of all of the above
Chose Nvidia™ Cuda as a parallel development environment.
Porting sequential code to a parallel environment is a challenge.

Rendering
Virtual try-on results will be compared with real photographs
Synthetically reproducing light reflection from complex materials such as human skin (Sub surface scattering) and is a major challenge
Interactive Ray Tracing
Pixel based shaders (GLSL or CGFX)

Comparisons

Reality Server (Mental Ray)
