Introduction to
Wood Grain Modeling
   Uses
     Computer       graphics and animation
     Cabinetry
     Design,   building, and construction applications
   Methods
     Artificially
                generated texture maps (Photoshop)
     Scanned Images
     Simulation models
Problems with tessellation

Major Goals
 User friendly GUI application
 Species specification
 Wood-cut specification
 Tree Ring database integration
User Friendly GUI Application
Species Selection
Species Specification
   Characteristics
     Colorization
     Noise
     Branching   (which creates knots)
