The Persistence of Vision Raytracer is a high-quality, totally free tool for creating stunning three-dimensional graphics.
As far as i can tell this is open-source, and i am not to sure if it is actually possible to make this portable because i don't know that much about programming or porting...

As you could read in the different licences, you may modify POV-Ray and you also may distibute the modified version... - ...but, if you may do so for running it as an App within the PA Suite, i don't know... - POV-Ray already does run on Windows-machines and it also already runs on Linux/Unix-machines... - As i'm german and don't speak english natively, it's hard for me to read all the 3 different licenses, just to figure this out... - ...but i'm going to ask the POV-Team within their Forum... - I'm a registered Member of www.povray.org ... 
...asked via eMail to a POV-Team Member...
the Distributor may rename, reorganize or repackage (without
omission) the files comprising the Software where such
renaming, reorganization or repackaging is necessary to
conform to the naming or organization scheme of the target
operating environment of the Distribution or of an established
package management system of the target operating environment
of the Distribution; and
(b) the Distributor must not otherwise rename, reorganize or
repackage the Software.
That looks to me like it can be repackaged into a PA format?
It basically says it is open source for those wishing to modify it's environment (tick) redistribute the modified version (tick), and rename our modified version (tick).
Looks good.

And I will definitely have a go with this some day !
But I'm not sure if it's really that useful to have portable as it could take quite some time to render.

..., and took 4.5 days to render on an Athlon 5600+.
The render time depends on the complexity of the scene, you describe, and on the size and quality of the resulting picture, you want to get...
I have several projects running with the Persistence of Vision Raytracer ( "Povray" )... - Some of them render that fast, that i'm running 'em on my ATARI 520 ST ( ...1 MB RAM, 8 MHZ, 16-bit Motorola 68000 processor... ) using Version 1.x of the Raytracer... - ...and i'm rendering about 2 frames per second, sometimes ( ...64x64 pixels at 8BPP for creating animated icons, for example... )... - Some other projects, i'm actually running, take 3 days per frame on my 2800 MHz P IV... - They're very complex and huge ( ...8x8 fullHDTV-Screens for posters and 2x2 fullHDTV-Screens ( ...which i rescale to simple HDTV using IrfanView... ) for fullHDTV-Videos... )...

I've asked the POV-Team for if someone may port Povray to the PortableApps-Format... - ...but since today the Team didn't answer... - So, i don't actually know, if it was legal... - ...but as "vf2nsr" says, it seems to be...
I would be very happy, if i could use more Computers for rendering my projects... - I often can't do anything else, at home, than watching my computers render several days... 
You can use more computers with POV-Ray in a Beowulf cluster. You should build a two or four node one.

That's true... - ...but what should i do then, when i visit my Mom or my Sister, for example ? - They both do have "only" one PC... - I may use them, sometimes, but i shouldn't install so many programs on their Machines... - That's, why i would like to use a portable Version of Povray... - ...and for maximum usability and performance, it would be great, if "POV-Ray Portable" would support PVM technology... - If i could use 2, 4, 16 or 256 PCs at once ain't important... - It's better to be able to use 2 processors instead of just 1... - The original Povray does use only 1 processor-kernel, even if the PC contains a multicore-processor... - Using a PVM-supporting Povray-Version makes using more kernels possible... - ...and i want to use more processor-kernels for increasing render-speed... - Most of my computers do have just 1 singlecore-processor... - ...but i also have a quadcore-PC ( ...4 times 3.2 GHz... )... - The maximum Power i can use with Povray is actually 1 time 3.2 GHz... - No matter, if i try using my quadcore or my fastest singlecore-PC... - "PVM-POV Portable" would end all the problems, 'cause i could use the full Power of all my PCs and when i'm not at home, i could additionally use the others PCs Power using the same Version of POV-Ray...
Till now they haven't sent any answer... - Maybe, they didn't read my eMail... - Maybe i should send a letter to them... - Maybe that would take some weeks for the letter to arrive... - Maybe the letter wouldn't arrive...
As it sounds legal to "repack the sources", someone should try to do it... - ...and if "repacking" is legal, it probably also is legal to "repack" it using the "PVM-patched" sources... - Wouldn't you agree ? - I would try it, if i was able to do suck work... - ...but my programming experiences concentrate at BASIC only, yet... - Okay... - I also know something about Java... - ...but that's not enough to build even a small applet...
Somebody please resume work on this))
