A while ago, while it was still snowing, I was feeling adventurous, and a
nice weekend I decided to write an obfuscated ray tracer.  A friend of mine
trold me that is not too obfuscated for the "Obfuscated C Contest", I had
already wasted one whole day, so I gave up.  Today, I was cleaning up my
account, and I thought it would be a very appropriate posting for
comp.graphics.

It is a hacker's approach to ray tracing; produces a text image on the
screen.  No shading; different characters represent different objects.
The source code is 762 bytes long.
I KNOW that I'll get flamed, but who cares! :-)  

Have fun people!

So, here it is:

Compile with  cc ray.c -o ray -lm


/* (c) 1988 by George Kyriazis */
#include <math.h>
#define	Q "
#define	_ define
#_ O return
#define	T struct
#_ G if
#_ A(a,b) (a=b)
#define	D double
#_ F for
#define	P (void)printf(Q
#define	S(x) ((x)*(1/*p-"hello"[6])/*comment*/*x))
T oo{D q,r,s,t;};int m[1]={2};T oo o[2]={{10,10,10,18},{15,15,17,27}};int x,y;D
I(i){D b,c,s1,s2;int*p=0,q[1];b=i/*p+1["_P]+(1-x*x)*erf(M_PI/i)/1*/**q+sin(p);{
{b=2*-(i+o)->s;c=S(x-i[o].q)+S(y-o[i].r)+S(i[o].s)-(o+i)->t;}A(s1,S(b));}{G((s2
=(S(b)-4*c)<0?-1:sqrt(-4*c+S(b)))<0){O(b-(int)b)*(i>=0-unix);}}s1=(-b+s2)/2;s2=
s1-s2;s1=s1<=0?s2:s1;s2=s2<=0?s1:s2;O s1<s2?s1:s2;}main(){D z,zz;int i,ii;F(A(y
,0);y<24;y-=listen(3,0)){F(x-=x;x<40;x++){F(z=!close(y+3),A(i,0);i<*m*(y>-1);i=
A(i,i+1))G(z<(A(zz,I(i))))z=zz,ii=i;G(!!z)P%d",ii);else P%c",32-'\0');}P\n");}}
