are now working. A runway light is defined by a point and a direction. The
point and direction are combined with the local up vector to create a small
triangle orthogonal to the direction. The two ficticous corners of the
triangle are given an alpha value of zero, the orignal corner is given an
alpha of one. The triangle is drawn in glPolygonMode(GL_FRONT, GL_POINT)
mode which means only the corner points are drawn, and since two have alpha=0
only the original point is drawn. This is a long way to go to draw a point,
but it ensures that the point is only visible within 90 degrees of the light
direction, behind the light it is not visible. This is still a long way
to get to drawing a point, but we use an environement map, with the direction
vector as the normal to mimic a light that is brightest when viewed head
on and dimmest when viewed perpendicularly or disappears when viewed from
behind.
- warning, there is a bug in how the current runway light direction vector
is calculated which will adversely effect runway lighting. The airports
should be regenerated in order to fix this problem.
The FGGlobals constructor does not initialise the locale pointer.
Under MSVC, uninitialized pointer have a value of 0xcdcdcdcd, not
0, so a test in mainLoop fails and the program segfault.
This patch set un initial value to locale.
This patch fixes some bugs for correctly reporting un-updated
configuration files, and adds support for a --language=<code>
commandline option, overriding the language specified by the OS.
KEMT (w120n30 scenery), and you will have to set the property
/sim/ai-traffic/enabled to 'true' to see the other plane (and tune
comm1 to 121.2 to hear the other plane's radio calls).
For sounds that play while a value is in transit, use time rather than
the number of frames to judge when to halt the sound because it will be much
more reliable on high performance systems. It currently waits 10 ms.
before stopping the sound, but you might want to fiddle it a little by
changing MAX_TRANSIT_TIME defined int fg_sound.hxx
really see anything different in the day, but as day turns to night the
panel smoothly darkens and the lighting component becomes visible.
Lights are wired to electrical system so if you kill power, you lose the
lights.
