Stephen Mardson McQuay a1c88a186e something about the changes I made (abs -> np.abs) made my stuff succeed more often 2010-04-30 11:56:01 -06:00
Stephen Mardson McQuay 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

Stephen Mardson McQuay cfcd1e15a2 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. 2010-04-23 16:29:31 -06:00

Stephen Mardson McQuay 3efe335563 moved the quadratic error calculation out of the baker method, and added a cubic version too 2010-04-02 11:06:17 -06:00
Stephen Mardson McQuay 700ccc8c25 created a test for tesing the cubic interpolation 2010-03-20 20:09:46 -06:00
Stephen Mardson McQuay 1fc988428d putting together a simple test case so that I can test my quad/cubic interpolator 2010-03-20 17:10:02 -06:00
Stephen Mardson McQuay 993c901cec properly catching the LinAlgError. also, prepping to change the run_baker method (more generic) 2010-03-20 11:34:24 -06:00
Stephen Mardson McQuay bd8f24d64f working on implementing the cubic interpolation. need to split that routine out of the run_baker method 2010-03-19 21:27:51 -06:00
Stephen Mardson McQuay 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
Stephen Mardson McQuay 9836fdcbfe added files. still not consistently getting better numbers 2010-03-18 23:32:24 -06:00
Stephen Mardson McQuay 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
Stephen Mardson McQuay a2d7b3f063 updated library files so that i don't have to edit the __init__.py files

Stephen Mardson McQuay b9ea6a3ac2 modified code to use Distribute (python's distribution framework) 
one should simply run `python setup.py install` to install these librarires
 2010-03-08 13:31:51 -07:00
Stephen Mardson McQuay 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
Stephen Mardson McQuay 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

Stephen Mardson McQuay 0ef6897aee made a simplex class, going to move this into the face class to simplify 2010-02-21 19:02:45 -07:00
Stephen Mardson McQuay 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)!!

Stephen Mardson McQuay 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!

Stephen Mardson McQuay 9064663600 added face information to the grid. i need to parse and add point->face information ... somehow ... 2010-02-07 20:23:19 -07:00
Stephen Mardson McQuay 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

Stephen Mardson McQuay 0f4daa9a9c fixed a little bug and getting good results again. still will have problems if you try to simply get a linear interpolation 2010-01-31 21:10:37 -07:00

Stephen Mardson McQuay 80720c45fe MAJOR: updated the baker method. it's more generic, and should allow me to 3D-ifiy it more simply. a ton of other things 2010-01-31 20:47:03 -07:00
Stephen Mardson McQuay 98b13fb8c5 merged the drivers, and am investigating the qdelauney manpage ... should've done this earlier :P
