13. Triangle Winding

• Triangle Winding considers the order of the vertices you specify to draw triangles:

  • Clockwise

  • Counter-Clockwise

• Why is this important? If using glFrontFace( GL_CCW ) (this is default mode)

  • Counter-clockwise is front facing

  • Clockwise is back facing - not visible!

• This can be reversed by glFrontFace( GL_CW )
