Lecture 19

• OpenGL color:
  • RGBA, not ARGB
  • usually 0.0 to 1.0, not 0 to 255
  • some objects determine range via float vs int
  • "1" is black while "1." is white
  • "255" is white, "255." is 255 times brighter than 1.0 white
• textures:
  • jit.gl.texture:
    • pre-process image: jit.rota
    • "flip" attribute
    • texture coordinates (Maya, etc)
  • old way: "tutorial 34: Using textures"
• animation:
  • jit.anim.drive
  • jit.anim.path
  • jit.anim.node

• tut31: Render destinations (also jit.gl.render help)

• "Everything's a Matrix": tutorial 37: noisy torus xfade

Hands-on:

• Create a plane (using a jit.gl.gridshape) for a floor
• place a couple walls (using more gridshapes)
• hang a playing video image on the wall (jit.gl.videoplane)
• place a moving/rotating object in the room
• animate the camera
• add lights + materials

• intro to physics
