In order to make a request or hear from the air traffic controllers, you must have your COM 1 radio tuned to the proper frequency for the request. Alternatively, you can use the Joystick & Equipment dialog box to program your joystick to access this menu. To access this menu, simply press Enter (Return) on the keyboard. Note: You will only be able to hear the air traffic control chatter if ATC audio output is enabled to confirm this is the case, open the Settings menu, then click Sound.ДЄll interactions with the air traffic control occur via the on-screen ATC menu. Although AI aircraft (i.e., those that you have turned on using the Aircraft & Situations dialog box) will always follow the guidance of the air traffic control, they will also work around your aircraft if you are not interacting with the ATC. Actually as far as I can see it (your description was a bit sketchy) your rasterizing process is half-way towards Vatti (raster colons or lines corresponding to the scanbeams), but you clip with 4 half-planes rather than polygons.X-Plane 10вЂ™s air traffic control (ATC) system is powerful and realistic when you want to practice real-world protocols, but completely unobtrusive when you want to just fly. Clipping an arbitrary pol by another one is more complex as you know but there is an efficient algorithm since the work of Vatti. It would make a lot of sense to clip it first with the exclusions zones. Дў) Initially your forest information is a polygon.

Shapes in shapefiles all come with their bbox precomputed, there must be a similar reason.ДЎ) I was skeptical too initially about implementing the w-n algo for one-one checks, but if you put actual numbers in front of your data (Ntrees*Nexcl*Nnodes) and divide by common flops youвЂ™ll probably end-up in the order of the second. вЂњ(Realistically a better implementation is probably to have polygonal exclusion zones with an AABB saved around them as an early-exit test.)вЂќ (Realistically a better implementation is probably to have polygonal exclusion zones with an AABB saved around them as an early-exit test.) In the case of an airport being excluded from a DSF, most of the trees are outside the airport, and on average half of them will be outside the first segment of the polygonвЂ™s contour, letting us skip a lot of checking a lot of the time. On paper itвЂ™s O(N) just like the winding rule, and itвЂ™s more restricted, but it has one really nice feature: if you are outside of ANY edge, you are outside the polygon and you can -stop the check early-.ДЇor something like a DSF where exclusion zones are small and most stuff is outside the polygon, the early exit is a pretty nice win. In a convex polygon test, you test whether the entity is on the left side of your polygon edges вЂ“ if you are inside -every- edge, you are inside. There is another option: convex polygon exclusion zones. One other note: a number of DSF shapes -are not points-, so the point-in-winding test doesnвЂ™t do us a lot of good вЂ“ itвЂ™s only useful for objects (where it is reasonably cheap) and trees (where itвЂ™s cheap by the tree but since there are a huge number of trees, itвЂ™s not cheap compared to what we do now). But it is also true that users will be able to make arbitrarily complex polygons вЂ“ WED makes it cheap to really make a complicated exclusion zone. There is no question that with if the user inputs a large number of AABBs (to try to simulate a complex shape) then the shear number of AABBs makes things expensive. In other words, AABB exclusion zones exclude many trees with a single very cheap test polygons exclude a single tree with a significantly more expensive test.

Okay вЂ“ youвЂ™ve now made each tree test вЂњNвЂќ times more expensive where N is the number of sides of the exclusion zone.Д«y comparison, with the box rasterizer, we simply _skip rasterizing entire scanline segments_ when a box excludes it. So you want to go exclude with a polygon. This AABB restriction is important for ensuring that the cost of forest rasterization doesnвЂ™t become amplified by the subdivision of the final output mesh into вЂњbucketsвЂќ for scenery paging and scrolling.

The forest code works by rasterizing an arbitrary polygon with holes _restricted_ to within an axis aligned bounding box. HereвЂ™s an example of why itвЂ™s not as easy as you think it is: /cgit/cgit.cgi/xptools.git/tree/src/Utils/CompGeomDefs2.h#n1676
