and if you remove
Code:div _ Null = error "div _ Null"
then dividing by zero (Null here for those don't understand the code) is just an infinite loop. Drunk haskell coding is fun!

wanna has some rings in sphere_tracing ?

return max(abs(length(p.xz)-r)-r2,abs(p.y)-c);

where:

r== radius ( ofcoz! )
r2 == the inner radius, but starting from the outer radius=r ! ( so its the difference from outer to inner radius! )
c == width of ring

otto must be proud ! ( --> lip-shitz )

return max(abs(length(p.xy)-r)-r2,abs(p.z)-c);
return max(abs(length(p.yz)-r)-r2,abs(p.x)-c);

^^ those are possible aswell ofcoz ;)
tobé : c'est du haskell ?

return p.y-sin(p.x*.5)*sin(sin(p.z*.5)*2.+time_0_X*2.4)*.4;
}

float sphere(float3 p, float r)

float cylinder(float3 p,float r,float c)

}

float octahedron(float3 p, float size)
{
p=abs(p);
return (p.x+p.y+p.z-size)/3;
}


HAVE FUN! ( ok, i fucked up the plane already :P )
also this could be helpful:

D3DXMATRIX mat_World;

float rotare[3]={ D3DXToRadian(180*ASMcosf(timez*.9f)), D3DXToRadian(270*ASMsinf(timez*.7f)), D3DXToRadian(360*ASMcosf(timez*.6f)) };

D3DXMatrixRotationYawPitchRoll( &mat_World, rotare[0],rotare[1],rotare[2] );
DX_Effect->SetMatrix( "matCamera", &mat_World );



shader-main:

"float4 main(float2 tc: TEXCOORD0) : COLOR0"
"{"
"float3 rayDirection = normalize(float3(tc*5., 1.));" // wrong xy.fisheye

"rayDirection = mul(float4(rayDirection.xyz, 0.), matCamera).xyz;"
[...]
ontop dont forget:

"float4x4 matCamera;"
