Code: vec2 grad(float n) { float angle = (n+t/100)*2*pi; vec2 gr = vec2(cos(angle),sin(angle)); return normalize(gr); }

No need to normalize here - gr is a point on the unit circle - already normalized.

las, would you like to write a tutorial about sphere tracing?

First we need that frakkin' time machine. Then I'll start to care. Actually people are already fine with the beginners and toolbox thread here - maybe a wiki would be a good idea - but this is not the place to discuss - you know where to find and how to contact me. And just to be honest from the beginning - I don't have the intention to write an article for hugi (at least not without the proper payment and the price just raised a lot :)).

this was kinda a compofiller that happened to win - smh had written his first shaders (as standalone programs) a while back, and we decided to combine+sequence+sync them at the party so we'd have an entry other than freestyle music :)

thanks for the tip las (the beginners' thread is incredibly fun to read, as well)
Code: if(y>0) { y = pow(y,0.9); x*=(1-(y)*0.003); } if(y>0 && y < 50 && x > 0) { x *= (0.70 + 0.008*(y - 15)); } float angle = atan(-y,x); float radius = length(vec2(x,y)); if(radius < 40*(angle+3.4)) duck_shade_duck(x,y);

my finest contribution?

I'll redirect Hugi readers to this paper, the theory seems to be well explained there. And las, how can you expect me to pay anybody for writing articles? Hugi is not for profit and it should be in the interest of the contributors to get featured in it.

Stop that crappy bla bla bla discussion. If you want to discuss - open a bbs thread (and enjoy the flamewar) or contact me directly.

Motivational thumb up for coda - I guess there's some more to opt. ;)
