hi folks,
this may be a noob and odd question. it seems most 3d renderers work by using the cpu's performance instead GPU's of the graphics card. why?
some friends and me came to this question by discussing the render abilities of gpu and cpu. we agreed that the gpu must have been design especially for render jobs, processing all graphical elements like shading, tracing and so on. but instead of using the graphics card renderers seem more likely to use the cpu to process. we figured the financial problems that a higher gpu weighting for rendering would hit owners and builders of renderfarms, but we could not imagine that this was the reason for weighting the cpu more (mabye because you can reach a higher performance paying less.. who knows).
surely there is an easy point, that explains the decision - please tell.
thx, onetoe
PS: maybe there are some links or papers to read, just post them please.
... the next question will be why 3d apps still concentrate on opengl, although directx seems to be more actual and "mighty". but before posing this there may be some basic stuff to clear, maybe it's just the wrong question or some false information..
