- remove splinter remaval / merging
- remove snap after adding colinear nodes
- added zfighting detector - intersects all generated triangles against one another
- this fixes ELLX, and to a large extent all 'large' airport self z-fighting.
- very small z-fighting still exists at 72 airports. This is down from over 100 before the fix.
- Use new SimGear API in construct to gather all tiles within a bounding box
- Bring in new clipper lib, which seems to fix more orientation issues
- Various debug cleanup
- Fix Find/Merge slivers - but leave it turned off
- New OffsetPoints for small speedup in GenApts - currently disabled
- reworked priorities.hxx/.cxx to make valgrind happy. It also allows us to add more features per area (like smoothing).
- remove TG_MAX_AREA_TYPES - we had a merge request for this, but this does essentially the same thing with the refactoring.
- fixed some edge matching introduced in multithreaded construct.
- tgconstruct objects now live for an entire stage. 1 for each thread - this introduced the memory leaks, and some issues.
interesting side effect is that we do less alloc / free, since we use std::vectors which when cleared, don't actually free
memory, so by the end, we've allocated enough entries for the largest tile.
- fixed linear feature issue in genapts850 - the refactor caused some of the old clean functions to remove too many polys!
with cgal, we need far less cleaning - just do what construct does, and we can still parse all airports, and lines are back.
results of OGRDecode, instead of ascii, completely different format
- move Utility functions to generate polys from line data into tgPolygon
( use this for both GenApts850 linear features, and OGRDecode )
- kill off old superpoly, and texparams
- add tgChopper which queues chopped polygons per bucket.
When saved, result is less files (each tile has 1 file per shapefile decoded)
Both genapt and ogrdecode now use tgChopper instead of Geometry/Util.cxx functions
- tgChooper acquires a global file name lock, so we can safely run genapts in
paralell with ogrdecode.
(this was dangerous before, as both could try to open the index file as write,
the loser would segfault, later )
- instead of expanding for each poly - account for shoulders when expanding base and clearing when building the runway.
- instead of doing a union for each base / clearing poly - add them to a list to do just one clip operation at the end. This results in anoth 2-3% performance increase, and allows another 10 airports to build. just 4 don't build in addition to NZSP.
- I can still get holes on helipads, but I think it's not a texturing
issue, as I can build the helipad, side extensions, or borders seperatly.
together, I can get holes.
