Aircraft altimeter w/FLTK

[Greg Ercolano]

We don't see many examples of FLTK used to render "realistic" instruments,
so I thought I'd make a mechanical aircraft altimeter simulation.

This is an FLTK widget where you can set the altitude to any value between 0 and 99,000 feet.
The demo runs the altimeter in realtime to show how the dial and drum numbers work:

I added this demo to my "FLTK cheat" page; here's the link:
http://seriss.com/people/erco/fltk/#Altimeter

Only took a few hours to make; most of the time was spent painting the images in GIMP.
Started with a few photos, and simplified them a bit, separating them into levels.

The goal was to show how one can composite PNG images in realtime to render
a realistic instrument with very little code.

The link includes a short gif animation of what the demo looks like when you run it.

OpenGL is not used, just straight FLTK drawing calls.

This is really neat! So I ported it to Haskell using the FLTKHS bindings: https://github.com/deech/fltkhs-altimeter to show off both the bindings and FLTK itself.

Cool, glad you like it and ported it!
I perused the Haskell code; nice, looks much reduced compared to the C++ code.
