Does the GPU effect rendering time and workflow speed?


#1

Hi guys, I’m always with this concern when thinking about new GPUs. Do graphic cards have to do with rendering, etc… cause many people say that the main power comes from the cpu when rendering/ working in a 3d program like Maya. Also does it help in After effects for instance?

Thanks :slight_smile:

It enhances the view port… so it helps while you work. I believe as far as render time is concerned - it does not affect it… both AE and 3D app. (I refer to Cinema 4D. Can’t say for others.) I could be proven wrong though. :slight_smile:

There are 3D GPU rendering systems, like Furryball.

Generally, GPU has been for previewing and CPU for rendering. But this changed in Ae CS6. If you use the built in 3D, and change your comp settings to ray-traced, then the GPU will be used for all of the ray-tracing operations, both in previewing and rendering. GPU is also used for accelerating certain effects, such as cartoon (for preview and render).

I believe this is also true of plug-ins like Element 3D.

I think a good GPU is becoming ever more important, and I guess as they improve, that more and more stuff will be being done on the GPU.

Speaking about Maya, it uses GPU to render the viewports so that you will be able to work quickly. And there are certain particle emitters in it which relies more on Hardware rendering (GPU) I believe.

True, as felt said, it seems that the GPU is getting more and more important… Maya has viewport 2.0 which uses some GPU power, and if I’m not mistaken it is used for particle/ physics simulations as well… but as for rendering it doesn’t seem to effect the rendering speed…

FurryBall it’s great.
But it’s bad if Maxon don’t use technology like that, in future releases of C4D.

I don’t get it how furryball for instance is achieving those high rendering speeds using the GPU, and autodesk haven’t implemented such system in their products…

I guess it’s how you write the software. Furryball itself costs €1000. Demos are always favourable to the product of course, but it looks pretty zingy. Products like this will be available for other 3D apps in a matter of time. Once it’s doable, it’s just a question of time.
