20c504056f - Add flag to specify whether or not we'd like to collect stats
- Fix amount of interpolation points to use during shape estimation

1bd1a79065 Add specific function to collect stats for BPTC so that we have one that preserves accurate running time measurements. 2012-10-31 17:48:53 -04:00

4c359f42a7 - Added a parameter to the PCA computation that returns the first and second
eigenvalues of the covariance matrix associated with the cluster.

- Compared results of testing the ratio of eigenvalues as a measurement of
  'linearity' for the different shapes, and output statistics.

- Added a #define that controls whether or not we do shape estimation using
  quantized AABB error or eigenvalue ratios. The former seems to be better.

71fbbca1ee Fix a few issues and make sure that when we write out to a file, only the intended values are reported. We still have to fix the accumulated stat reporting and make it thread-safe. 2012-10-31 17:48:53 -04:00

87375f4c14 Change signed to unsigned in order to match the function pointer typedef prototype.
Changed the function prototype to match that of the typedef in the rest of the library, and fixed a bug where we would iterate too far with the initial buffer.
