Gotta say, the depth of field on this render is fantastic.

Looks like the cover artwork for Radiohead's Kid A.

hmm i'll be off now to check out then; that's really nice for a programmer to hear actually, cheers!

Wicked landscape you have there.
I will try the software.

thanks; hopefully it'll work if you're running a 64bit os (xp or vista), lemme know how it goes
π: 0 β©: 1
I have not installed it yet, I have the 32 bit vista. Think that be an issue? Other than longer render times...

hmm it just won't run, 64bit is a different architecture.

I noticed, was afraid of that.
Maybe you should work it into a program for sale. Never know

hehe, nothing like a few grand for your effort.

effort = $
You really never know till you stick your toes in the ice water and see just how cold the B really is man.

hey that is really cool but mine seems broken ... [link]

curiously it seems to not be loading the honolulu / hawaii data properly but still running... hmm
well, maybe someday i can provide you with a proper rendering system to test

lol - what do you export the .RAW files from? Or do you write them yourself?
π: 0 β©: 1
that raw file i converted myself from text heightmap data for a university assignment last year: [link]
π: 0 β©: 1
how did you convert it? anyway, nevermind that 
π: 0 β©: 1
nopes, everything happens by c++ in kinda immediate mode keyboard controls or with little console mode / commandline apps

it does look rather icy

very nice.. so, you created the rendering engine? .,. it looks great,, the GI.

thanks

This is great, why is it in scraps?????????????
π: 0 β©: 1
in some ways i'm not really satisfied with it, but as it's better than my most recent render i think it's time to swap them... i'm glad you like this humble bunch of pixels though

Looks spectacular. Just the sort of place penguins would love!

this is probably the first real render i've done with my rendering system; actually just recently i added glossy materials to it, hope to have some nice renders of that soon. thanks for the fav

Great picture!
The lighting and the DOF really rocks! Where does this patchy look on the rocks (pun not intended) come from? Is it a texture or the result of the terrain's triangulation?
BTW: Inkscape has some L-Systems for plants . Not sure if this is of any help to you though
π: 0 β©: 1
i have my own l-system tools btw, from some time ago
and yeah, the faceted look is from the low heightmap resolution. glad you like it too, everyone seems to want it super smooth
π: 0 β©: 1
Of course you don't have to use Inkscape to actually render them but you could take their L-Systems and render them with your own tools (i mean because these examples they have produce plant-like structures).
π: 0 β©: 1
yeah that's actually a great idea, since i seem to have little talent for making something nice with that grammar.

I really like the blur. And the colour of the sky is so romantic

You use an interesting rendering style. It seems that each pass builds on the last with an almost random sampling. I have always processed each pixel one at a time with a point[i,j] matrix (each point having a color). I must admit you get much better results. Do you have any links that I could read that explain a little about what is going on βbehind the scenesβ in your renderings?
π: 0 β©: 1
i can also do "linear" rendering, and that's indeed what i'd been using for 99% of my rendering "career"
essentially what i'm doing is solving a monster integration problem - you integrate the ideal image function (which you get by ray tracing at real-valued pixel co-ordinates, not just integers) over the pixels, over all the visible wavelengths (i use a spectral light representation), over all time, over all other integration dimensions (each time light bounces it introduces extra variables that need to be integrated over, to arbitrarily high dimension). with my current approach, i swallow that integration problem whole, sampling the entire space at once in an efficient way (importance sampling, multiple importance sampling, ...) rather than solving little sub-integrals per pixel.
this approach to monte carlo light transport was first described by veach in his 1997 phd thesis (also known as The Bible in rendering circles), "robust monte carlo methods for light transport" available here - [link]

Thank you! I've added that link to my favorites

cool, have fun reading it! it's a monumental achievement that will give you something even after many years of study.
btw, i have another rendering in my scraps you might be interested to check. i usually put all my more technical stuff in the scraps, it's definitely more for maths/coding types than those interested in my "art".

heyhey, long time mate! hope you're well
π: 0 β©: 1
sure!
i was just browsing through your gallery again and i must say all of your renderings are just amazing. are they still all done with your homegrown raytracer?
