  • f178dc084b Updated unit tests. It seems we had a bug which was causing an excessive number of vertices to be generated. Not sure exactly what was wrong by the refactoring has fixed this. However, it still needs testing in Cubiquity to verify. David Williams 2015-05-19 23:14:31 +02:00

  • 5ce0d9c3e0 Cutting down and simplifying Marching Cubes code (also now slower...). David Williams 2015-05-10 19:43:09 +02:00
  • 3937dc3c61 Applying test to a larger region so we can more easily benchmark the performance (otherwise the VS profiler can fail if the test runs too quickly). David Williams 2015-05-10 11:40:58 +02:00
  • 16fca2529b Moved Config.h out of the 'Impl' folder. It should probably be considered part of the public API as users may want to adjust it for their purposes. David Williams 2015-05-09 08:58:14 +02:00

  • 09253a7bcc Removed a few uses of '#ifdef SWIG', mainly from areas where they would no longer work. e.g where the code has been templatized since the #ifdef was added so we can see that the SWIG version of the code is out of date and won't build anyway. David Williams 2015-05-08 21:08:43 +02:00
  • 3c31643e4f Exceptions are now part of the PolyVox public API (client code may need to catch them) but the utility macros we use to throw them are still private implementation details. David Williams 2015-05-08 16:15:11 +02:00

  • d8a422955d Now that PolyVox is header only we have no further use for the POLYVOX_API/LOCAL/SHARED macros which wrap API import/export. David Williams 2015-05-08 15:04:17 +02:00

  • 12fdeb8e52 Removed old chunk map. Removed flush(Region) function as it's a bit trickier to implement with the new hash table, and it's not clear that we need it. David Williams 2015-04-13 23:51:18 +02:00
  • 1e0e8a8c16 Fixed calculation of volume size in bytes. David Williams 2015-04-13 23:48:33 +02:00

  • c562341db0 Added a second PagedVolume to the tests with much higher allowed memory usage. This makes more sense when testing random access, as low permitted memory usage causes disk IO to become the bottleneck. David Williams 2015-04-10 16:56:19 +02:00

  • 65f39e7b57 Made the values signed ints, as otherwise the casting was doing something strange on 64-bit systems. David Williams 2015-04-01 16:29:19 +02:00
  • 5d220c5d57 Added extra lookup tables to avoid the need to multiply y/z deltas by 2/4 each time. David Williams 2015-03-31 23:58:01 +02:00

  • b415e5c5f3 calculateAmbientOcclusion() now works with both RawVolume and PagedVolume. David Williams 2015-03-30 11:44:25 +02:00
  • d000616d3e Revert "Ambient occlusion test now uses RawVolume, as it need a fixed size volume to create a temporary array." David Williams 2015-03-30 11:24:48 +02:00
  • 413bb95b1a Passing parameter as const ref. David Williams 2015-03-30 11:01:08 +02:00
  • 7f96005985 Commented out optimized path in sampler as it doesn't work now that we are using Morton ordering for the data in chunks. However, we can probably reinstate such a fast path if we give some thought as to how it should be done. David Williams 2015-03-29 09:58:28 +02:00
