Light and Shadow in 2D

In the future:
On a 2D space, drop some light and check its shadow.

Setup

A rectangle 125x32.
Beam Sources shooting red light with various angles.

Helper info about canvas, positioning and color pallette in this doc.

Reasoning

TBD

run

# dependencies
go get -u github.com/llgcode/draw2d

# run
go run ./...
open canvas.png
# test
go test ./...

next steps

• Light the wall based on light hitting in
• Render obstacles that will prevent the wall from lighting

Much later...

• Monte Carlo to make it faster!
