Hi folks,

I've been off the groups for a few months on account of my PC being on a 
boat crossing the atlantic (moved back home to England). But anyway, here's 
some stuff I've been working on this week for Paul Bourke's next short code 
contest (as mentioned on pov.general and his website: 
http://local.wasp.uwa.edu.au/~pbourke/rendering/scc4/ )

The dawn scene is basically finished, and it's entire source code is:

#local 
p=function{pattern{granite}}isosurface{function{y-.3+p(x/10,9,z/10)}contained_by{box{-9,9}}}light_source{<3,.5,8>,1}media{scattering{2,<3,2,1>/9}emission<.3,.4,1>density{function{.1/(y+1)}}}sphere{0,1pigment{granite

poly_wave 4}scale-7*y+9hollow}


The grassy scene's currently a bit too long, and has a boring sky:

light_source{99,.8-z/2}background{<.7,.8,.9>}#macro 
R(V)vturbulence(2,.5,6,V)#end#local i=0;#while(i<16384)#local 
p=mod(i,128)*(z-x)+(z+x)*i/128;#local 
p=p+R(p/70)*20;cone{p-5*y,.2,p+R(p/9)*5-3*x/*+2*z*/,0pigment{rgb 
y*2+z}}sphere{p-y*9,4pigment{rgb.9+z}}#local i=i+1;#end

Any suggestions on how I can make those a few bytes shorter?

Post a reply to this message

and if you look at that
;#local p=p+R(p/70)*20;

well
maybe
#local p=p+p*R*2/7;

mountain scene... wowow. i think you may have just raised the bar on
expectations.

A couple of improved versions of the grass, both within the 256-byte limit. 
Not sure which version I'm going to submit. Opinions?

I prefer the 1st one with the cloudy sky, the colors are better.
256 bytes code ! that's mindboggling :-|
Your mountain version is great too

These are both for the original grass scene.

Remove the "+z" from the grass pigment.  The resulting color is a little
strong, but i think the hue is closer to most grasses.

Replace the background <.7,.8,.9> with <6,7,8>/9 to save one byte.  The
color is *slightly* darker, but the difference is barely noticeable.

Wow that's *exactly* what I changed before developing my newer versions of 
the grassy scene! You must be psychic!

The +z was an attempt to get a difference in hue between the lit and shadow 
areas, but to be honest it doesn't really look bad without it and it saved 
valuable characters.
