View Full Version : Has anyone programmed a GI renderer?

I'm just looking for fellow programmers that have programmed a GI renderer, or have a special interest for GI to discuss the technical aspects. I will soon be programming my own renderer with shaders for a university project. If you are interested in chatting, I have ICQ (59216599), MSN (roue(@)sympatico.ca) and you can add me on AIM using my ICQ number.

I'm researching global illumination for my PhD. Tinkering wtih a radiosity renderer atm. Well have been tinkering with it for a year or so, keep deciding there's a better way of doing it and starting all over;)

Well, that sounds cool, I sent you an add request on ICQ if you want to chat about GI :)

Currently I'm more into programming a monte carlo based renderer with irradiance caching... But I lack some understanding of the basic concepts (which results in my renders being physically inaccurate).

By the way, what made you choose radiosity? Not to sound rude or anything, but my general impression was that radiosity was "dead" as most people were shifting to path tracing based methods using various optimization techniques (including photon mapping) since radiosity couldn't cope with some natural phenomenons.

Path tracing is very much the hype at the moment yes, for some very good reasons. But radiosity is still being actively researched, and I personally find the subject more intriguing than monte carlo based techniques.

Additionally, when you do research you have to take some note of what your superiours want you to research, or they get a bit iffy about giving you the money to do it :shrug:

Well, radiosity is alot faster for sure ;) Have they found ways to do caustics with it?

Yeah... I know the feeling...

Toxic (open source)

Those seem like cool projects, except that the toxic renderer is apparently not in development anymore.

But honestly, I would rather not look at the source code of other projects. Partly because it's often very unclear, but also because I want to understand and implement things by myself.

Don Vito, I saw you added me on MSN, I look forward to discussing GI with you :D

Hi there,

guys its great that i stunbled upon this thread.i am plannin to do some project like are u guys are talkin abt. i am plaanin to specialise in the lighting and rendering dept.

btw m an engineer. i hav some programmin experience...still hav lots to learn.
hope i will be able to do some contrubution to this group.

guys i don use ICQ...but i use yahoo and MSN.

my yahoo ID is: rockesh99
and MSN is : rockesh99@hotmail.com

u can mail me at rawkesh@gmail.com


hopin to see reply soon
