  1. UV Mapping CSIS 5838: Graphics and Animation for Gaming

  2. UV Mapping • Mapping U of 3D (x, y, z) coordinates to 2D (u, v) plane • Example: Simple “spherical” mapping in Blender:u = tan-1(y/x)v = z

  3. Conformal Mapping • Preserves angles locally • Defined in terms of lines drawn through space • Minimizes distortion in mapping

  4. Least-Squares Conformal Mapping • Pure conformal mapping impossible for complex shapes • Best solution: Minimize squared error over area • Most algorithms iterative, “tweaking” mapping until good solution reached • “Seams” create places where constraints not used
