Adaptive Quadtrees (paper) #914

Open boberfly opened 7 years ago

boberfly commented 7 years ago

Apologies if this is already in the codebase or not so practical for OSD's use case: http://www.graphics.stanford.edu/~niessner/papers/2016/4subdiv/brainerd2016efficient.pdf

I'm curious about this paper in relation to OSD, is there a plan to have an implementation similar to this? Or if anyone has a good idea on how to implement this. Cheers!

Yes, there is interest in this approach and there has been communication between the co-authors and the OpenSubdiv team (beginning prior to publication). Priorities for 2016 unfortunately needed to address other areas, so we hope to dig deeper into this in 2017.

Filed as internal issue #142045.

Just thought I'd link this here for more info for others (last section of the video): http://www.gdcvault.com/play/1024353/

Working on it - pull requests are in the pipeline, but we are hitting some hardware / API limitations that were not immediately visible with the prototype code from the paper.

Thanks for the update @manuelk

Hi all, has there been any progress on this? I did notice a patch builder but it was more or less scaffolding for upcoming changes I'm guessing? Cheers.
