Im basing my statement on simple algorithmics. Radiosity solvers , while not using extremly comple algos, are to be run on a very high number of samples to solve the problem, Thus, they are inpractical to achieve interactive frame rates on today (and tommrow) hardware. There are experiments for real time radisoity using last generation GPUs coupled with clusters of very fast computers, using paralel processing, and which can achieve a interactive frame rate. However, they do need a very large number of CPUs.
@ "How on earth can you make such a claim?" Try to put yourself at current with latest GPU technology, and lighting algorithms. Then you will be able yourself to make educated statements, providing you can understand the problems. Also, you should try to undertsand the complexity of global illumination problems. @"Why not wait until we see what can be done with it" It wont make any difference. I can wait till the end of time. Anyway, maybe the closest thing to "real time radisoity" which can run on today top hw, are lighting solutions based on precomputed radiance transfer algorithms. While working at their best with low frequency lights, they can be used to generate some global illumination effects, such as as interreflections on materials, soft shadows, subsurface scattering. Note that the technique still relays on a extremly computational intensive algos, which are done in a pre-process phase. ----- Original Message ----- From: "McCormack, Chris" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, November 29, 2004 12:52 PM Subject: RE: [hlcoders] Realtime radiosity & Source ? > Maybe he is basing it on the leak. hmmm > > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Michael > Shimmins > Sent: 29 November 2004 10:42 > To: [EMAIL PROTECTED] > Subject: RE: [hlcoders] Realtime radiosity & Source ? > > > How on earth can you make such a claim?
