const GeoTessOptimizationType& geotess::GeoTessMetaData::getOptimizationType ( ) const
inline

Execution can be optimized either for speed or memory. If optimization is set to SPEED, then the following optimization strategies will be implemented:

  • for each edge of a triangle the unit vector normal to the plane of the great circle containing the edge will be computed during input of the grid from file and stored in memory. With this information, the walking triangle algorithm can use dot products instead of scalar triple products when determining if a point resides inside a triangle. While much more computationally efficient, it requires a lot of memory to store all those unit vectors.
  • when performing natural neighbor interpolation, lazy evaluation will be used to store the circumcenters of triangles that are computed during interpolation.
  • when interpolating along radial profiles, every profile will record the index of the radius that is discovered. That index will be the starting point for the binary search the next time binary search is implemented. Each GeoTessPosition object will store 2d array of shorts, short[nVertices][nlayers] to record this information. Might be ~1MB per GeoTessPosition object (they could share references to the same short[][] as long as they don't break concurrency.
Returns:
