  10. Forum

Request to remove v3.3.0 branch, Dan has done this. Request to improve benchmarks, this would be good to do. Request to move INVALID_IDX definition to header, it is believed that this is indicative of a deeper linking issue rather than an issue in itself, Nick to reply to question.

  1. Fast Sweeping

Nick advocating removing testing logic from the PR. Ken to leave in until this feature has matured slightly, then tidy up. Brief discussion about unit testing in general as it is solving many purposes. Would be worth separating out benchmarks, regression tests, sample code and debugging data from unit tests.

In case of no zero crossing in all or part of a grid, Jeff wants the same topology but different values. Never useful to know if sweep did something or not. Algorithm should return original grid not an empty grid. Ken agreed and will revisit this.

Andre asked about what should happen at the SOP level if a vector field is passed in to be used for zero crossing. Should produce an error in this case.

Fast sweeping SOP can either handle pairs of grids containing one SDF and one extension field or one SDF with multiple extension fields. Not clear what to do here. Best option seems to be to produce a warning if more than one SDF is passed in.

  1. 7.1 Release

Dan to do 7.1 release as Ken and Nick are preparing for Open Source Day. Last two PRs are 746 (fast sweeping) and 775 (openexr 2.5 fix). Nick to merge 775, Ken / Dan to look at DCO issue and then once merged, 7.1 can be released.

Decision to hold off on merging other PRs until after 7.1. Next time, a separate release branch would be preferable here.

  1. NanoVDB

Question about how to deploy. Two options were considered 1) adding NanoVDB into the existing OpenVDB repository as a "feature branch" or 2) initially releasing NanoVDB as a separate repository and then integrate it into openvdb later. All voted in favour of option 1.

  1. Next Meeting

August 18th, 2020. 1pm-2pm EDT (GMT-4). Open Source presentation will be August 20th. 1pm-2pm EDT (GMT-4). Dan unable to attend next meeting.
