#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.

Normal human beings, would just have done something like this: for(c.width=99,i=18;i;x.stroke(new Path2D('M'+[4+i,47-i,14,4,43,7,A=43-S(t=S(t*2))*i/.6,B=7+C(t)*i/.3,A+9,B+1,52,8,80,11,83+i,53-i])),x.fillText('🧘‍♂️',A,B))i-=9
u/danny@hille.dk

😝😝😝
u/danny@hille.dk

Some might even put in the effort to test their code: for(c.width=99,i=18;i;i%2&&x.fillText('🐒',A,B-2))i-=9,x.stroke(new Path2D('M'+[4+i,47-i,14,4,43,7,A=43-S(t=S(t*2))*i/.6,B=7+C(t)*i/.3,A+9,B+1,52,8,80,11,83+i,53-i]))

u/magna

I had a RGB CRT setup, but I hadn't been able to fit any interesting patterns: d/7512
u/tomxor

I had a look at yours magna, they are true crt, much more realistic i think. The scan lines on this are just a sideeffect I exploited and it was easy to add colour distortion in the R().
u/magna

Here we go: d/10843
u/C010011012

is it a cellular automata?
u/tomxor

Yes and no, it's a fractal n=T(0|(i/w+f^f-i/w)/(t**.7+6)) which is just a more elaborate variation of serpinsky triangles to produce more interesting patterns. Some fractals are automata, but not all automata are fractals, see here: https://en.wikipedia.org/wiki/Rule_90
u/tomxor

The implication is serpinsky triangles are computationally reducable, meaning it does not have to be computed in the same way as a cellular automata i.e state can be computed at step t directly without traversing intermidiate steps.

oooooh, I love dithering! Nice one!
u/tomxor

me too :) I didn't realise how simple the algorithm was before no, and it can be done in a single pass because it's only half a 2d kernel. Tweaking the coefficients (*R) can be fun, e.g 7*R=>5*R, 3*R=>5*R better preserves the dark and light areas in this image.
