Demos

• Homework 5 a WebGL program
  • Single array of data, vertex only.
  • Both shaders are very simple.
  • Drawing technique: drawArrays
• Homework 5B
  • Single Array of data: vertex, vertex, vertex ... vertex, color, color, ... color.
  • Color is passed from the vertex shader to the fragment shader by varying.
• Homework 5c
  • Single array of data: vertex, color, vertex, color ...
• Homework 5d
  • Array of data: vertex, color, vertex, color
  • Array of indexes: p1, p2, p3, p4, .....
  • New drawing technique: drawElements
• HW 6
  • Draws old style off files without color and normal data.
  • Style of HW5-5C above.
• Barycentric Coordinates
  • Complex vertex shader
  • Uses CW, CCW, gl_FrontFacing
  • gl.cullFace, glEnable
• Triangle Computation Demo
  • We didn't use this in class, but it shows dot product, cross product and such.
• HW6 (We have not looked at this as of 11/14)
  • This shows the full projection matrix. (But not camera)
  • Wire shaded front faces.
  • Solid back faces.
  • Depth testing.
• Interpretation of berycentric coordinates
