+Performance
+- Depth Testing, aka Z-buffer
+- Culling: don't render what you can't see
+
+Terms
+- Winding: by default, primitives that follow in CCW fashion are front facing
+
+Projections
+- Orthographic: glOrtho(), define visibility in a *volume*
+- Perspective: gluPerspective()
+
+Transformations
+- Viewing: specifies the location of the viewer or camera (must be specified first)
+- Modeling: moves objects around the scene
+- Modelview: describes the duality of viewing and modeling transformations
+- Projection: sizes and reshapes the viewing volume (squishing 3D data down into 2D)
+- Viewport: a pseudo-transformation that scales the final output to the window

+Matrices

+- Projection
+- Texture

+Buffers
+- Color Buffer
+- Depth Buffer, aka Z-buffer
+- Stencil Buffer
+- Multisampling Buffer
+- Accumulation Buffer: this buffer allows you to render to the color buffer, and
+  then instead of displaying the results in the window, copy the contents of the
+  color buffer to the accu-mulation buffer.
+- Front Buffer
+- Back Buffer
+
+Terms
+ - Dithering: simulate displaying wider range of colors on on systems with small
+   amount of colors
+ - Texture Filtering: process of calculating color fragments from a stretched or
+   shrunken texture map   
+   
+OBJ Loader
+- glGenTextures()
+- glBindTextures()
