    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.

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

Projection Faster and Uncompressed

u/@noel

I love this one and I follow the logic, until the z & w performing. I know it's a bitwise AND operation on z and w, but I don't actually grasp it.
u/@noel

I mean on this one: x.fillRect(i, j, 1, (z & w) / w)
u/joeytwiddle

Here (z & w) / w is the height of the rectangle. If that height is less than 1, then the canvas anti-aliasing renders a grey pixel, instead of a black one.
u/@noel

Thanks u/joeytwiddle Now I think I get it. (z & w) ensures that the value of z remains within the range of the canvas width 'w', and the dividing by w normalizes the height value. Great trick!

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!!
