StrandStorm

Real-time Hair Rendering and Dynamics

Features:

• Control hair generation and interpolation [1]
• Kajiya-Kay and Marsehner et. al. shading modes [2,3]
• Hair-to-hair shadows using deep opacity maps [4]
• Physically-based simulation of strands using discrete elastic rods [5]
• Hair-to-hair and surface-to-hair collisions with lenght constraints [6]
• Basic phong shading and shadow maps for surface illmunation.

How to build & run:

1. Clone repository.
2. cd into projects root directory.
3. mkdir a build directory.
4. Use CMake to configure and build into the build directory.
5. Run the executble generated.
