* Generate Texture Coordinates
    * generate for cylinder
    * generate for boxes
    * generate for ground plane

* Texture Loading
    * Load texture onto cylinder
    * Load texture onto box
    * Load texture onto ground plane
    ** Texture Replace 
    ** Texture Blend (light + shading)

* Filtering ???
    * Magnification Smooth
    * Magifnication Simple
    * Minification Smooth
    * Minification Simple

* Mesh now uses:
    * per face normals
    * per vertex normals
    * per vertex texture coordinates

* Visualize Per Face Normal Vectors

* Compute Per Vertex Normal
    * Simple Average
    * Weighted Average
    * Visualization

* Check Crease Angle for Per Vertex Normals
    * Modify angle to be 15, 25, 35

* Shading
    * Materials Diffuse
    * Materials Specular
    * Materials Design

* Move light source

* Overview Navigation

* First Person Navigation

** Procedural Ground Plane Generation

10/19: 
  Simple per face normals
  if time: per vertex normals
