wrapping up a night. there isn't enough consistent improvement to merit using this method. i must have a bug somewhere.

working on the containing simplex problem. the get containing simplex function works, if the point is in the domain. I am trying to force the domain to contain the point (placing points along perimiter of the mesh). I am not doing that right, but have to run

working on the guarantee simplex routine. I have a test case to try it out against, and need to look at visiting neighbors of faces adjacent to points.

i think part of my problem (why i'm not always getting win), is that i do not guarantee that the simplex contains the point (especially with the random clounds; i think that the connectivity-based lookup is doing that fine

working on getting baker to work in 3D. the code runs, but the numbers are odd. I suspect the rectangular grid, and am going to try a random cloud of points.

finally added proper (in my opinon) exception handling to the grid's run_baker method. it should properly autocorrect, and switch the extra point lookup scheme to connectivity-based if solving the system of equations yields a singular solution

partially implemented using new data structure in point lookup
...
I spoke with Dr. Gorrell about first trying to call the nearest-neighbor routine, releasing the trapped exception where the matrix ends up being singular, and trapping it in the grid object's run_baker, where I could then call the connectivity-based lookup routine. Those are my next steps, as well as starting to think about pushing the 3D front ahead this week.

I'm going to hurry and clean up this method, but for now it is verbose, and uses sets. i'm going to just check it in for future reference

by next friday i need to have implemented a way to select between normal kdtree point lookups, and nearest-neighbor lookups. Hopefully i'll have that done tonight.

mostly fixed a bug in my qdelaunay parsing. implemented a blender viewer ... mostly
...
the qdelaunay app doesn't alway display all faces for a point. lame. I worked around it by creating the point-> face relationships manually.
There is a max recursion something happeneing when I try to save so pickle. look into this.
I spent some time writing a visualizer for blender. 10 lines of code. simple stuff.
next steps would be to move the KDTree into the mesh object. GOOD LUCK (me)!!

minor: added point to facet information to the grid object

I really think that I need to create my own point object, and hang the facet information directly off of that. right now there are simply parallel arrays for q, numpy.array(x,y), and {point_index: [adjacent faces]} ...
work to be done!

getting stuff from qdelaunay

mostly spent time trying to figure out subprocess (which i though i already understood). I am concerned for what will happen with large datasets.
next steps include:
1) design data struture
2) implement slurping of stdout into this structure
3) drink coke
