12/29/97 - sky tweaking

So, by building the sky in the flattened shape, we can have it be
|
|
very foggy at the horizon and clear blue overhead.
|
|
|
|
The other important feature of this model is the colours. We
|
|
colour each vertex of the dish individually to allow for cute
|
|
sunsets, a darker blue overhead than at the horizon in daylight, a
|
|
gradual darkening of the sky as a function of altitude for very
|
|
high altitude flight - into space. Also we tint the horizon more
|
|
in the direction of the sun so that sunset starts where the sun
|
|
goes down - and the sky remains blue on the opposite side of the
|
|
sky - then as the sun gets lower, the colour spreads outwards all
|
|
around the sky and the black of night creeps in slowly from the
|
|
opposite side of the sky from the sunset.
|
|
|
|
We also like to tint the bottom edge of the sky with white - even
|
|
in broad daylight - so it looks fuzzy - even when there is very
|
|
little fog to achieve that effect.
|
|
|
|
We use a text file that contains a lookup table relating the sun
|
|
angle relative to the horizon to:
|
|
|
|
* The colour at the top of the sky dome,
|
|
* The colour of the horizon nearest to the sun
|
|
* The colour of the horizon farthest from the sun
|
|
* The colour of the texture environment blend for the clouds.
|
|
* The fog colour.
|
|
|
|
We can then tweak that file to set up all the conditions. The
|
|
realtime system interpolates the horizon colours all around the edge
|
|
of the sky.

12/29/97 - Ground collision detection
|
|
|
|
12/29/97 - glut windows or something for panel area - consider 3d
|
|
panels, careful of texture memory problems.
|
|
|
|
1/5/98 - bzflag sound code might be able to work for us.
