Tasks

• Task 0:

 Benchmark Piyush polygon union written as an .oct file against the current .mex interface to clipper in geometry 3.0

If task 0 shows bad performance of mex, then

1. Clipper native oct interface instead of mex

if mex is ok

1. Add F. Martínez, A.J. Rueda, F.R. Feito algorithm

2. Salvage work from last GSoC

Maybe

• Add CGAL interface for poly clipping

Discoveries

• The performance of oct interface was much better than the current mex interface when the polygon Union (polyUnion) which was written as .oct file was used as benchmark against the current .mex interface to clipper in geometry 3.0.

  .oct interface : Elapsed time is 8.98838e-05 seconds.
  .mex interface : Elapsed time is 0.0109348 seconds.
