[simpits-tech] MSFS Visuals

[David C. Allen]

Hello, Hope everyone had a happy holiday season!

I have been doing more work trying to understand MSFS Visuals.
If I block off all of the windows except for the two forward 
windshields then I have the following viewing angles:

Pilot's angle to the left 34 degrees (View through Left forward Windshield)
Pilot's angle to the right 72 degrees (View through Right forward Windshield)

Copilot's angle to the left 34 degrees (View through Right forward Windshield)
Pilot's angle to the right 72 degrees (View through Left forward Windshield)

Both the Pilot and Copilot down angle cutoff is 15 degrees (Both 
Forward windshields)

So I have created an image of the 737's flight deck and the viewing 
angles of the pilot and copilot.

Now if I take that information and make a 3d model I get the following:

The Black portion is the Runway
The White portion is the area of the runway that can NOT be seen from 
the flight deck forward windows. This is the 15 degree lower window 
cutoff angle.

The Purple lines represent the Pilot's left angle of 34 degrees 0 
degrees Straight ahead and the right 72 degree angle.

The Green lines represent the C0Pilot's right angle of 34 degrees 0 
degrees Straight ahead and the left 72 degree angle.

The two Orange lines would be hidden from view when the pilots & 
Copilots eye point are at the proper elevation.

The above image is looking back at the flight deck from a point in 
space, you can see how the White portion is hiding the area of the 
runway that can NOT be seen from the flight deck forward windows.

This also shows the lines in 3d

This image is perpendicular to the to the runway (90 degrees) and at 
the pilots eye point elevation. This also shows that the 34 and 72 
degree purple and green lines are at the same elevation as the pilots 
eye point elevation. The 0 degrees Straight ahead lines (green & 
purple) appear as dots. The two orange lines are hidden behind the 
straight ahead green & purple dots.

This image is looking forward from the above and the right side of 
the flight deck.

The final phase will be to get some help from someone who knows how 
to do airport scenery and place the lines in a known locations and 
then experiment with MSFS visuals until all of the lines can be seen as dots.
