NVIDIA Real Time Hair Presentations at Siggraph 2008

 
 

NVIDIA Presented Two Talks on Real Time Hair Rendering at SIGGRAPH 2008:

NVIDIA Sponsored Session: Real-time Hair Rendering on the GPU

A video of the presentation, including a live demo, can be seen here.

Simulating and rendering realistic hair with tens of thousands of strands is something that until recently was prohibitively expensive for real-time use. In this session, we discuss how to render realistic hair with high geometric complexity in real-time on the GPU. Amongst cover topics including efficient creation and rendering of high amounts of geometry for hair (essential for creating realistic hair especially when in motion), shading, self-shadowing, level of detail, and important performance optimizations. We also talk about how to use next-generation hardware tessellation to make creating and rendering hair much more intuitive and efficient.

Let's Get Physical: Real Time Hair Simulation and Rendering on the GPU

Simulating and rendering realistic hair with tens of thousands of strands is something that until recently was not possible in real time. In this talk we present a method for simulating and rendering realistic hair in real time using the power and programmability of modern GPUs (Graphics Processing Units). Our method utilizes new features of graphics hardware (including Stream Output, Geometry Shader and Texture Buffers) that make it possible for all simulation and rendering to be processed on the GPU in an intuitive manner, with no need for CPU intervention or read back. In addition, we propose fast new algorithms for inter-hair collision, and collision detection and resolution of interpolated hair.
