    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

#DooM 2.5D #bumpmap textures

u/tomxor

Same concept of XY displacement, but X displacement needs to be inverted when a surface is aligned along Z to give the illusion of the light comming from the observer. Completely unrealistic lighting tricks.
u/deobfuscate

I don't feel like I can make any more dweets with so many good ones like this roaming around.

#PCB #trace #bumpmap

u/tomxor

Getting on the bump train with a different method. This one displaces X and Y in proportion to distance from light source, which creates pixel gaps on one side (specular highlights), and overlapping pixels on the opposite (becoming shadows).

wow thats chrisp!

bump mapping remix

u/Joachim

Really nice #lighting
u/@noel

Beautiful. I need to dig into this, to understand how this actually works.
u/rodrigo.siqueira

Wow! Replace X^Y with X|Y to generate Sierpinski triangles. Replace Math.min with Math.max for a more dramatic effect. Remove |0 for improved golfing (a minimal visible effect on top alignment). Replace "t*1.2" with "C(i+t)*6" for the "water effect".
u/jellyedwards

Wow that's amazing!!

Do Fall ! #game

u/tomxor

Use left + right (focus the iframe with mouse first)... If you hit the top, you die, if you fall too far, you die, if you fall too fast you fall through things, you die. High Score: throw u=B<0|B>72?u:t|0
u/tomxor

Forgot: If you fall just right, you live :)
