df35cb174b made a get_error function that is generic and functional. I'm still getting unsavory numbers for the cubic, 2-D case on my single test case. I will have to try out more refined grids, albeit the quadratic is consistently improving results for my case. 2010-05-05 23:03:12 -06:00

3dcc10ea0e 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

f089848a1b 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 2010-03-18 23:50:40 -06:00

b33159f8a9 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. 2010-03-18 23:18:59 -06:00

9a1b8d14b2 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 2010-03-05 08:58:07 -07:00

a25e6d03d1 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.

2792329eaa cleaned up the method (removed print statements) i'm ready to now add this method as an option to the mesh object 2010-02-21 20:52:51 -07:00
Stephen Mardson McQuay
a3d72ed200 wrote the method that returns grid objects based on connectivity
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

6c4c6d4cfe moved teh grid code into the grid class
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.

2cf9a0b574 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)!!

9ff48f4c12 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!

50daeb5d74 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
