The disadvantages of MPL +are: (1) any contributor can pull out their contributor and (2) the difficulty to +reliable proof that what is in the system comes from a particular source code. + +Ken will share a google doc with a summary on why we are moving to Apache 2.0. +We will use this draft to communicate to contributors to sign their approval for +moving to Apache 2.0. + +John Mertic will contact DreamWorks to inform them of this decision and to +follow through with the proces. + +It is noted that what we need are contributors after the year 2018, since the +previous contributors are covered by DreamWorks. + +4) PR-1760 +Dan talks about Initial Adaptive Grid Prototype (PR-1760). + +Dan tried to use the Point Advection class and go through the interpolation +through a different type of Grid. To make it work, Dan needs to modify the use of +Value Accessor, which was designed for Sparse Grid. He changed it to use an +Accessor from the Tree class itself. Essentially, this is pushing the creation of +an Accessor down into the Tree. + +All the unit tests pass. + +Dan asks for people to look at the PR and to provide feedback. He will try to +fix the Windows build problem. He suggests that we notify AutoDesk of this PR. + +5) Half-Grid Support Presentation by Greg + +Greg extended the support of HalfGrid to other tools, such as +CreateLevelSetSphere, FastSweeping, LevelSetFilter, LevelSetMeasure, +LevelSetMorph, LevelSetSphere, LevelSetTracker, LevelSetUtil, MeshToVolume, +RayIntersector, RayTracer, SignedFloodFill. He experiments with LevelSetFilter. + +We discuss ValueType and ComputeType, which is similar to StoreType and +ReturnType. + +6) Next meeting + +Next meeting is on March 19th, 2024. 2pm-3pm EST (GMT-5).
