Re: [Bf-committers] Cycles movement blur
It would be nice if this was built-in to how cycles worked, rather than a hack that you have to do manually. And even then, it's more a stop-gap solution. Ideally we'll (eventually) want randomly sampled motion blur, to eliminate strobing and to let you see the full motion blur (even if noisy) early in the render, so that you can tweak it in the viewport without having to do the full render (similar to DoF right now). Of course, I don't expect that terribly soon. ;-) Motion blur, particularly deformation motion blur, is a non-trivial problem in raytracing, if I understand it correctly. --Nathan On Tue, Nov 15, 2011 at 2:52 PM, Carsten Wartmann c...@blenderbuch.de wrote: It is already possible to get this kind of motion blur in cycles.

Re: [Bf-committers] Cycles movement blur
Is interesting a full unbiased solution to motion blur can be instead or sampling (rendering) a point in time scene (static) to fully sample(in a random or pseudo random) way an interval scene (like the aperture size of the camera) though this may be more efficient in terms of required samples it can be costly in terms of memory because you have to have simultaneous access to a range of scenes instead of one, I don't know how Cycles engine deal with memory and frame scenes tough ... those are my two cents ;) De: Knapp magick.c...@gmail.com Para: bf-blender developers bf-committers@blender.org Enviado: martes 15 de noviembre de 2011 22:46 Asunto: [Bf-committers] Cycles movement blur I was just thinking today that Cycles could do motion blur without taking a big CPU hit.

Would this not require a BVH rebuild on each pass?
