Progress Report:
The initial run of fenceline, north side of the alert area, running from the ramp edge to a point half-way between the taxi line for the parallel taxiway and the taxi line to/from the south "throat" to the hammerhead, was just completed.
The fact that the base (and, of course, everything on the base) is not laid out true N/S/E/W causes problems when trying to place several objects that have to be butted up against each other and aligned correctly. It's taken me this long to establish the latitude/longitude off-sets for each section of fence, as well as incremental heading adjustments, to keep it running straight. But the first run is in, and the off-sets will be the same for any other fence runs that are perpendicular to the taxiway/runway. After establishing a latitude off-set of -0.0506 seconds per fence section, a longitude off-set of +0.1138 seconds per fence section, and a heading adjustment of +0.1 degrees per 10 sections of fence, the line from the ramp edge to the turning point went in smoothly. It took 80 sections to produce that one run of fence -- now you see why I HAD to solve that texturing problem so I could use my custom objects in an XML file; Microsoft displays all 80 sections, but only keeps 11 polygons in memory -- 29.8 frames per second with the system locked at 30.0 fps, virtually no impact on performance of the sim.
It's going to take at least another day or two to establish the off-sets and heading adjustments for the run to the south end of the ramp, but that will also establish the off-sets/adjustments for any other fence runs that are parallel to the taxiway/runway.
Sorry for making this post so detailed; but I want to be sure that -- within the limits of Microsoft's product (and there are MANY limits, unfortunately) -- I'm doing as much as I can for accuracy of what DOES go into the final product; it helps if I can see my descriptions in writing
.
One of those limits is the lack of proper scale that Microsoft used to create the "tradeport" version of KPSM -- the space simply was not provided for accurate placement of objects that used to be there on the airbase. As a result, although there should be at least minimum wingtip clearance when taxiing near the fenceline, it may result in a tight squeeze. I've turned off "collision" on the fenceline; this will keep Microsoft from "crashing" the aircraft when it's in close proximity to the fenceline. I've also limited the height of the fenceline to 6 ft so if there are points where wingtip clearance isn't 100%, the user will not see his wingtip penetrated by the fence posts. (Wingtip clearance shouldn't be a problem for the FB's, but it could have been a problem for the KC's.)
