I added a sort of real-time depth of field rendering option to control high frequency rendering noise in the distance.

The approach I took is to render to texture with z stuck in the alpha channel, mipmap and then draw the texture covering the entire screen, using a shader that reads the alpha from top level pixel and then picks a mipmapped pixel depending on the alpha value. With some parameter tweaking it actually does not look as bad as it sounds  grin

Haven't tested on Linux or Mac yet, so I might be violating some opengl or shader fu across the board..

Looks very nice. But i dont know how to get that to run. Can u post a Version whit EXE Datei please.
And would be nice to hat a Lodsystem in this Engine.

you can find it here (windows 32 bit)>http://code.google.com/p/boxplorer2/downloads/detail?name=win32-2.00.zip&can=2&q=
I also have a version for mac OS 10.5..

THank you, but dont work. "invalid_parameter_noinfo_noreturn in msvcr100.dll not found"  huh?

Maybe the 32bit? I hav 64.

....ok i used it on 32bit system and the same error.

I downloaded the c++thing ńh "vcredistx86" but it dont worked.

Question: for the same number of iterations and level of details, how much faster is the parallel processing of a fast GPU? 80 times faster?

i would love to visit this one on boxplorer:

Not sure what the speedup is. A lot though. But the renderings aren't exactly comparable. Lower quality lighting, ambient-occlusion, depth of field etc. A decent DE is very important for performance so if raystep multiplier needs to be really small to avoid overshoot, the formula is not going to fly.

Once a formula drops below a couple of frames per second I lose interest quickly undecided

I could try code up a fragment.glsl for that hybrid, but i haven't paid too much attention to the various tweaks in composing the hybrids. Do you know what the composite formula is for that render?

I'll drop a recent win32 build on code.google.com when I get around to it, one that includes the DoF hack.

i see.

Same here, anything algorythmic 3d @ 25fps i love. Do you mean that the lighting and the shadows have a fixed mesh size and have less resolution? not raytraced?

I was wandering what DE is?

You are too nice! ...i was just joking about seeing the exact render in the image, i think that is probably magnified *50. it is gorgeous but i think it would be a distraction from the organised development list that you have already, with more formulas and visual tweaks... If ever it can handle some varied hybrids etc, that would be more than i wish for. Actually, i dont have a fast GFX at the moment, 1fps @ 320pxl fullscreen. (radeon from 1997 inspiron laptop). am checking out some PC's this very moment!

I kindof wondered if it could be possible to section a small part of a formula and explore in zoom mode,
i.e. instead of map = X,Y,Z, between -1,1
map = X,Y,Z between -0.6, -0,5

so that the total render field would be one thousandth of the volume... just curious in theory what that would mean.

I wonder where Rrola is? I think he may be on holiday, but also i suspect that it must be hard for him handing his masterpiece to open source and seeing it taken in all different directions that he wasnt expecting. he may have had an aneurism and joined hari krishna, that would be i would do if i had a program that good.  Thanks Rrolo, that is engenuous.


It is fantastic to see that it is advancing! very clever stuff i wish my maths and coding was up to it!

the image is from this page of formulas abotu 20 images from the top.

@navi:
grab the .dll and put it inside .exe's folder..

same also on windows xp sp3, installed msvcp and msvcr files but got this message:

unable to locate procedure entry point in msvcr100, even if i fixed it i am sure there would still be dozens of other things.

@navi/ant123:  huh?
is it ok your Gpu and drivers? can you run this one > http://www.subblue.com/projects/mandelbulb ? or this other > http://syntopia.github.com/Fragmentarium/ ? what about upgrading the operating system? and did you download all the components, like c++ stuff, sdl, etc.. ?
try with the original boxplorer here >http://sourceforge.net/projects/boxplorer/
maybe there's something (like a .dll) missing..you could use this tool 2 find out if there are missing dependencies > http://www.dependencywalker.com/
 
an alternative is 2 compile the software on your machine..

Thx the original Boxplorer works fine. Its a very nice Programm. smiley

I just tried this last night on a clean XP machine.
After installing http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=a7b7a05e-6de6-4d3a-a423-37bf0912db84
it starts up fine and from there on it's all about the graphics card & drivers.. Not sure what's up with your machine's configuration?
If i get around to it, i'll compile a version w/ visual c++ 2005 or 2008, perhaps that'll easy the pain.

Like visual says, if you have a compiler and some inclination, try compile it yourself on the target machine.

"@mariushi, thanks i installed that redistributable file... same message. dont worry! the number 1 works enough for a sneak peek ( i think i had to install 1 2 extra dll's for 1..)  and my gfx is too slow i just get a few fps. i have to wait till i can borrow a gamer pc.

i wonder if there are any gfx based 2d mendelbrot set programs that can animate zooms in realtime, like e-999 power zooms... except that 1 frame at e999 probably takes even a graphics card 2 minutes!

@navi
the syntopia article... thanks! i have coded a bit of sse4 so i put a comment on there i dunno if he posted it.

Interesting program, looks like it could have potential: http://syntopia.github.com/Fragmentarium/
It also has a tendency to crash my GPU video driver sometimes. I'm somewhat hesitant to experiment with new drivers
which could cause issues with other installed programs. I'm almost tempted to clone an older HDD, and run the Boxplorer
experiment, along with Fragmentarium only.

oh i didnt realise that all had to do was recompile it.

point me to a easy compiler and the code and i will get round to it sometime.
