Lecture 20

misc

• Fog parameters on an object: tutorial 35 (old lighting)
• jit.gl.text3d help page
• jit.gl.sketch - like a 3D LCD object
  • examples/.../jit.gl.sketch-a-etch

Graphics Hardware

• software vs hardware rendering - GPU paintball

• shaders and slabs
  • Shaders: tutorial 41 (and jit.gl.shader help)
  • Slabs: tutorial 42 (see slab-readback subpatch)
  • example: slab/gauss6x-example.maxpat
  • example: anim/anim.node.planets
  • example: camera.node.examples/

• "mrt" examples folder: multiple render targets

• Advanced Reading:
  • Create Dynamic OpenGL Scene Processing Chains
  • Max and OpenGL: GL Texture Delay
  • jit.mo
  • Eliminate redundant replicated vertices with jit.gl.model + gl.multiple
  • jit.matrix-3d-render, jit.gl.gridshape-morph
  • jit.gl.render.grid, .render.grid-sketch, .render.multi-iter

Hands-on Experiment Continued / Hw assist:

• make a floor plane/grid so you know where you are
• position a camera for a good view
• put an object on the floor
• light the object with jit.gl.light
• Animate scene attributes with jit.anim.*
• filter the images of your world with slabs
• filter the images of your world with jitter filters
