Hi all, 1. What did you get done this week: I was traveling, so unfortunately not much. I improved the flow accumulation computation by integrating voxel traversal algorithm which I thoroughly tested. The explanation is here [1] and code [2].
Then, with mentors we updated the plans for next few weeks. 2. What do you plan on doing next week? I will implement better integration method - Runge-Kutta with adaptive step size. The following step is to implement gradient computation used locally on-the-fly to get the velocity field (I won't be using the gpde library). 3. Are you blocked on anything? No. [1] http://trac.osgeo.org/grass/wiki/GSoC/2014/ImplementationOf3DRasterFlowLine [2] http://trac.osgeo.org/grass/browser/sandbox/annakrat
