Recent advances on motion blur rendering

by syoyo

Last week, I’ve talked/discussed a lot with renderists over the world about the offline renderer.

After the discussion, I think we’ve confirmed that there is still a lot of things to do in (global illumination) rendering.

One of it is fast & efficient computation of motion blur, this still has not been solved fully in the context of RenderMan style renderer, as well as ray tracing renderer.

After I’ve researched recent advances on motion blurring, I found interesting paper.

Almost all previous motion blur technique focuses on Lagrangian motion(e.g. moving objects).
They propose new Eulerian motion blur techniques.
(Some people may imagine this approach is similar to image-based motion blur technique)

Natural phenomenon & fine geometries(fluids, clouds, gases, furs, etc) become dominant part in the (production) graphics, thus I think such a Eulerian motion blur techniques will be developed & used intensively near the future.

Here is another recent papers about motion blurring.

まだまだ、グラフィックスの研究はやるべきことは一杯あるなー、と実感。
まあモーションブラーについては前にも指摘したと思いますが、今一度。
