> Hi,
> 1. What did you get done this week:
> I implemented adding attributes to each segment of a flowline. I added
> column with velocities and values of input 3D raster along the flowline.
> The result can be visualized by using vector color tables (v.colors) in 2D
> and 3D.
> I started writing r3.gradient module based on the gradient function in
> r3.flow. The module is already running and giving correct results, I will
> add it to addons once the gradient function is moved to library.
> 2. What do you plan on doing next week?
> I will try to parallelize the gradient computation with openMP, the
> structure of the code is already prepared for that. Then, I plan to add
> more tests.
> 3. Are you blocked on anything?
> No.
