Boxplorer: an interactive intro ;-)

category: gfx [glöplog]
@psionice, @svo: I'd like to make it run on OSX, but have no means to debug it - if you could help, please do. Platform-specific code is only in shader_procs.h.

I'll take a look. Need to get it to compile first :)

...and it compiles and runs. Had to fuck around plenty with sdl first - the solution was to rename the main function in shadershrink.c. Otherwise it was finding duplicate _SDL_main symbols, which doesn't make much sense, but hey these things aren't logical ;)

It looks pretty glitchy / possibly broken, showing an empty black window but a mandelbox fractal shows now and then so it's obviously running the shader and outputting an image now and then. I'll have a proper look at lunch time, running this during work time might get me in trouble ;)

Ah, now I look stupid. The black window with flashes of fractal was... me moving the mouse around, so it was randomly looking at black space or fractal. Doh!

Anyway, it runs fine on mac now. I get a respectable 1.5fps on the initial view, at 640x480 on a radeon 2400. That's pretty bottom end video card, it should be a lot faster on anything recent or decent. I'll package + upload in a bit.

Mac port: http://www.interealtime.com/Boxplorer.dmg

It should run by just double-clicking the app, but I guess you'll need to go command line to load a config file (not tested it). And hopefully it doesn't require the sdl framework to be installed. Maybe it requires 10.6, can't remember what I set it to.

Oh, and press esc key twice to quit (I thought it'd crashed when single esc didn't work, always read the docs first etc.)

...yep, config loading from command line works fine. If you copy the .app out of the dmg and run it, it'll save a file called last.cfg alongside the app (saves writing your own).

Also, after playing with it at 320x240 for a bit and adjusting the iteration count for speed or quality.. this rules!

Improvement suggestion: reduce the iteration count while moving, then increase it when stopped (I did this when I wrote a mandelbrot explorer a while back, but with 0.5x resolution while moving, full res + aa while stopped).

I don't know if it's the Mac-port or not, but is it not possible to zoom in?

it's done with the right mouse bu... oh. sorry.

gloom: read the docs first, not last :) Should be left button to 'move' in, I think it's f+up/down arrows to actually zoom (change fov).

shadershrink.c is a standalone utility, it doesn't have to be linked in.

Features I want to add:
  • FPS hacks. In deep zooms, high iter count is necessary, but lowering the resolution is a nice idea. I'll also try progressive rendering (the Windows port of Puls renders in 4×4 blocks and refines on edges).
  • Fractalforums guys want interpolation between saved configs (Catmull-Rom would be nice).
  • Mandelbox hybrids look awesome (each iteration has its own parameters).

I'm usually moving using Alt.

gargaj: the Mac has had rightclicks for... ages. :) Even the joke is getting old now.

psonice: oh, I don't mean changing FOV, I mean actually going into the structure and having it "zoom in" like a regular fractal.
added on the 2010-09-08 14:47:56 by gloom gloom
Also, judging from the comments, I should really make a HUD with controls and all the parameters.
added on the 2010-09-08 14:47:57 by rrrola rrrola
@gloom: press F to set FOV mode, then use the up arrow key to zoom in.
added on the 2010-09-08 14:49:18 by rrrola rrrola
I think alt mode should be default, but keep the 'look around while moving in straight line' using alt. A HUD would be good.

It wouldn't take much to rewrite this as a proper osx app actually, maybe I'll do that once it's stable.

Anyone care to tell me how to compile boxplorer under linux? :)
added on the 2010-10-20 10:53:34 by psonice psonice
gcc -lSDL -lGL boxplorer.c -o boxplorer
added on the 2010-10-20 11:27:53 by ringofyre ringofyre
cool, thanks :D
added on the 2010-10-20 11:34:12 by psonice psonice
Thanks go to joooo.
Wouldn't compile for me but my graphics is crap so opengl struggles. Good luck....

It's not me trying it (I'm on mac and have a working port already :) but another guy, who was showing a nice mandelbox render he's using to test the speed of his new box. It took an hour to render :O And he has an nice new nvidia 460 card in it. Something must be done!

running at around 20-25 FPS when inside the mandelbox @ 1920x1080 on a Radeon HD 5870

So yeah, the Amazing Boxplorer ;-) is now on sourceforge.

Anyone wants to contribute ports|shaders|ideas|code? Psionice?
