Ah, thanks, that described the main issue here. The reliance of Eulerian Geometry. It also explains why I suck at FPS.
Well, this likely means I am going to stay away from any form of 3d programming in the future, as most of the Eulerian Axioms I have been told tend to be things that I tend to have issues seeing how people can agree with that. But then, I am the person that I typically try to copy various conventions of art styles rather than try to draw realistically... because well, in recent years I have learned that I do not even perceive the world in an Eulerian manner. So yeah, this is kind of a good thing really, I can now stop exploring 3d Programming. As well, the whole thing will mostly only cause more issues than it is worth, as I have never been able to agree with the basic Axioms that make up Geometry. And well--a few of the articles on that link just made that really apparent. Hmm--well, I suppose there is not much I can really do about this now. I mean, I could write up some Axioms on Noneulerian Geometry... but nobody apart from me would find them useful--so I may as well be twiddling my thumbs and doing basket weaving... actually those two options would be thought of as more useful. Well, thanks--that link kind of helped me out in more ways than one. Just have to grok what I have learned from this for a bit. ~Katrina On Friday, June 18, 2010 06:51:28 am ZuM wrote: > The concept is the same of a cluster, but it is in a single processing unit. > A cluster requires several processing units, this is the main difference (or > else we cound consider an I7 a cluster, but anyway). > > This is all i know how to explain, but basically the GPU is specialized in > several areas where a normal CPU isn`t and would suffer to emulate. > Also the calculation of vector and matrix operations (which are the most > common in Graphics) are really faster because of, again, the speciallized > architecture for this. > > I don`t have a link to any white paper that i can remember right now, but > please have a look at this link of wikipedia, that may help you understand a > little more about GPUs and then you`ll clearly see the reason why it`s > almost impossible to emulate through software at a decent speed. > > http://en.wikipedia.org/wiki/Graphics_processing_unit > > 2010/6/18 Katrina Payne <fullmetalhar...@nimhlabs.com> > > > Thanks ZuM > > > > I apologise, I may have been misinterpreting the TLA, of GPU to mean > > "Graphics > > Processing Unit"...
