I'm trying to put some things together into one big library to see what I can do with it all, just got some fire going and applied it to a starfield.

Played a bit with Doob's GLSL sandbox.

Hmm .. just shows a gradient grey background ...

To be honest I've got no idea what the system requirements for webgl are.
I just adapted one of my shaders to fit the sandbox layout.
Strangely, after it was running fine in Chrome, it refused to work in Firefox until I removed one of the loops...
Did it show "compiled succesfully" ?

It worked fine for me in Chrome when I looked at it. Very impressive, and runs nice and fast too.

I got the same as Benny, strangely though your other example in the gallery worked. I probably need to update Chrome.

That's just a version of my entry edited by someone else.
Funny

Strange, both are compiled successfully - but both versions show a grey gradient only. Seems like this the following line 155 is never true:

Code: [Select]

if (t < THRES)

Hmm ... did not understand this function anyway:

Code: [Select]

// find the nearest intersection point of the ray with the scene
float intersectScene(vec3 p, vec3 d)
{
   float t= THRES;
	for (int i=0;i< BALLS; i++) {
		t= intersectSphere(p, d, sphere[i], colors[i], t);
	}      
	
   return t;
}

Seems like you return the intersectSphere value of the last ball anyway ... yawn... or maybe it is just too early for me ;-)

6:23am is indeed very early

The ray parameter "t" (as in origin + t * direction) always contains the shortest distance to the yet intersected objects.
And it's fed back into the "intersectSphere" function to discard intersections that are further away.
So after the loop it contains the point on the ray which is closest to the camera (or "THRES" if nothing was hit).

As I had successfully tried this with different browsers, browser versions and OSes, it's probably just an ati vs nvidia thing again...

benny! · « **Reply #509 on:** February 27, 2012 »

@Hellfire:
Thanks for explaining that... I just tested the code on my PC @ work (NVIDIA) and it works like a charme.

Well done! Looks pretty cool ... is this the first step for you doing some javascript stuff, too ;-)

Played a bit with Doob's image .

What a lovely set of balls.

Slowly learning with a heap of help from you guys on here... just thought I'd post what I've got going on so far (It's basic). I have many many ideas to put into action still. Slowly but surely.

About a month ago I wrote some OpenGL code to make a retro-flat-shaded game engine. Next step is to upgrade the OpenGL to be shader-based, rather than the old-style. Then to extend the functionality.

benny! · « **Reply #513 on:** February 28, 2012 »

Looking awesome, copse.

Reminds me a bit on the Amiga game called Virus/Zarch.

A current WIP for a certain party in Easter. Gonna be an invite so I'll actually have to finish it this time too

There will also be a huge-ass Displayhack article on it after it's done describing workflow/custom tools/effect implementations/why it's going to be open-source

That seems almost impossible to play with any accuracy. Amazing graphics though!

Had the same thoughts, looks really trippy with the small field of view!

Excellent and inspiring stuff all!

Yeah, the field of view is an interesting legacy from days of limited processing power I guess. There's a nice remake of Virus available here with Basic source, which has the option to switch cameras to and from the small field of view to other options. The controls for Virus were too hard for me..

Kirl · « **Reply #518 on:** February 28, 2012 »

Excellent, thanks for the link copse, the game really rocks!

Played it for a few mins but will defenatly revisit it. The controlls work much better then I had expected them to actually.

Are you going for something like this?

Only as inspiration in terms of the retro look. Zeewolf is more of an inspiration to me than Virus/Zarch, even though I never played either. Once I have it shader-based with shadows, I'll add some more game-like elements and then start experimenting with variations on the look.
