Either it takes ages to render or all I get is a white screen.

I see, what kind of hardware are you on? It's my first one so might be some bugs when displaying the image.
I had a look at the code... Seen some of it before.
Some kind of greetings would have been nice move. *cough*
Code: 0(232) : warning C7506: OpenGL does not define the global function saturate
+ tons of implicit warnings.

Code: #extension GL_EXT_gpu_shader4 : enable

Compatibility killer.

Fix it in a way it runs on my machine and you might get a thumb up.

ATI 4000 and something here.

Remove the #extension line, replace half with some other name, and replace all the saturate(x) with clamp(x, 0.0, 1.0), you can make a macro for that, and it should be fine everywhere else.

You should have replaced the red with green so it would look more like matrix... back to the 1998s.

Have it working in Rendermonkey now.
Shader takes like 20 seconds to compile.

I recommend http://www.opengl.org/documentation/glsl/

And you are wasting space with stuff like
Code: vec3 rgb(float r, float g, float b) { return vec3(r/255.0,g/255.0,b/255.0); }

Don't do that! ;)

Motivational thumb for 1st attempt! Looks very Matrix-ish :)

Thank you all for the feedback, and will start working on everything now. The new version will be up asap. I managed to upload the wrong NFO (ofc you should have been there las), so I added a new NFO in the compressed file, and requested pouet.net to update it on the page.
I inserted a single .exe file in the compressed file. 1024x768 fix just to see if you get it to work
honnestly this is kickass! congratulations :) looking forward for more ^^

digitalerr0r: Nope, 'half' is not part of glsl either.

btw, you can use GSA if you at least want to ensure it compiles outside "nvidia-glsl": http://developer.amd.com/tools/shader/Pages/default.aspx#download

This is great Feedback, I really apprechiate it. Now I also know what's wrong in our other prods. So, thanks, will spend the next days rewriting and optimising the code. I'll keep you posted. :-)
And when it's working, I'll insert a green version as well. :)
Nice first try! Hope you bring another to Solskogen :)

Hurra! \o/

Still white screen on my NVIDIA 450 GTS - Win7 (64) - some error output to the console could help us to tell you what's wrong with it. :)

P.S.: You misspelled psonice.

P.P.S.: Anyways here's your motivational thumb, but 250 marching steps are really a-lot - you should need far less steps. I go with 128 at absolute max. Usually one should be fine with 64 steps.

las, i've got the same setup and it works here... i'm using his original version in the zip...?

I managed to get the whitescreen myself now so it will be easier to debug. Will also fix your PSes las. :)
white screen here too

Can't run it here (lack of windows outside of vmware..) but looks cool from the screenshot. Interesting shapes. And thanks for the greets :)

Hi guys, I added new files branded with "fix". Is this any better? :) If you get a white screen, please try the other exe version as well. Thanks!
I also added a high-res image file of the result, in case anyone wants that.
doesn´t work here... (nvidia, win7)
