Final Project

Eternal Return of Fakemotion

• Point light falloff

Eternal Return round 2

• 2 moving lights

Eternal Return round 3

• Weird Orbits

Also this

Changes

1. Support customized specular hightlight (Ns). This is impl-ed as exponent in specular reflection calculation.
2. Add more light attenuation functions (inv_sq, inv_linear)

Work 11 - Animation

3rd return of fakemotion

Note on file name: "d" is for delay, "s" is for step

Changes

1. add a default writer to Drawer to simplify drawing (maybe stdout?)
2. add animation commands

Notes

1. For me, the following command does not produce the correct result:

$ magick simple_100*.png -delay 1.7 img.gif

This seems to be the issue.

Solution: put -delay 1.7 before the src files:

$ magick -delay 1.7 simple_100-*.png img.gif

And the result image animates as expected.

My version of magick:

$ magick --version

2. Common material light parameters here

Todos

1. possibly, refactor Matrix code into regular matrix and a Mat4 class

Work 10 - MDL

        location: Vec3(250., 400., 0.),

Light locations:

• (250., 400., 0.) - bright yellow
• (250., 100., 0.) - bright green
• (250., 250., 0.) - bright blue

Uses nom (a parser combinator) to parse mdl file. Each line is parsed individually.

Changes

• Add dependency on nom and thiserror crates
• Refactor lights module
  • rename to "light"
  • separates original config into Light and LightProps (light properties of an object)
  • implement point lights
