14 * A simple clear-screen sky.
17 * Less detailed terrain.
18 * Texture - but no MIP-mapping.
19 * Texture - but no bilinear blending.
22 12/29/97 - sky tweaking
24 So, by building the sky in the flattened shape, we can have it be
25 very foggy at the horizon and clear blue overhead.
27 The other important feature of this model is the colours. We
28 colour each vertex of the dish individually to allow for cute
29 sunsets, a darker blue overhead than at the horizon in daylight, a
30 gradual darkening of the sky as a function of altitude for very
31 high altitude flight - into space. Also we tint the horizon more
32 in the direction of the sun so that sunset starts where the sun
33 goes down - and the sky remains blue on the opposite side of the
34 sky - then as the sun gets lower, the colour spreads outwards all
35 around the sky and the black of night creeps in slowly from the
36 opposite side of the sky from the sunset.
38 We also like to tint the bottom edge of the sky with white - even
39 in broad daylight - so it looks fuzzy - even when there is very
40 little fog to achieve that effect.
42 We use a text file that contains a lookup table relating the sun
43 angle relative to the horizon to:
45 * The colour at the top of the sky dome,
46 * The colour of the horizon nearest to the sun
47 * The colour of the horizon farthest from the sun
48 * The colour of the texture environment blend for the clouds.
51 We can then tweak that file to set up all the conditions. The
52 realtime system interpolates the horizon colours all around the edge
55 12/29/97 - Ground collision detection
57 12/29/97 - glut windows or something for panel area - consider 3d
58 panels, careful of texture memory problems.
60 1/5/98 - bzflag sound code might be able to work for us.
