17 Flies through height maps, optionally animating the instantiation and
18 destruction of generated tiles; by default, tiles 'grow' into place
19 (height gradually increased up to correct value). In windowed mode the
20 following key controls are available:
21 left, right
23 Turn left and right.
24 a,w,s,d Move left, forwards, backwards, and to the right, respectively.
26 1,2 Decrease and increase manual speed, respectively.
28 Spacebar
30 Return to automatic control.

33 crackberg accepts the following options:
34 --root Draw on the root window.
36 --window-id number
38 Draw on the specified window.
39 --window
41 Draw on a newly-created window. This is the default.
42 --install
44 Install a private colormap for the window.
45 --visual visual
47 Specify which visual to use. Legal values are the name of a
48 visual class, or the id number (decimal or hex) of a specific
49 visual.
50 --delay microseconds
52 Delay between frames; default 20000 (1/50th of a second).
53 --fps Display the current frame rate, CPU load, and polygon count.
55 --crack Use all possible methods to animate tile instantiation.
57 --boring
59 Do not animate instatiation at all; use this to get standard
60 landscape generator behavior.
61 --letterbox
63 Drawable window region has a 16:9 aspect ratio, regardless of
64 actual window size.
65 --lit Enable lighting.
67 --flat Flat shading (OpenGL will use one color per primitive, rather
69 than interpolating betwixt vertices).
70 --wire Wireframe.
72 --nowater
74 Do not display 'water' (forces negative values to zero, and se‐
75 lects a different coloring method).
76 --visibility float
78 Value in range [0.2,1.0] (default 0.6) specifying proportion of
79 viewable XY plane which is to be drawn upon.
80 --color string
82 Selects color scheme. Use with no or bogus argument for cur‐
83 rent list.
84 --nsubdivs integer
86 Number of times to recursively subdivide each triangular tile.
87 Each increment increases total triangles by a factor of 4; for
88 instance the default setting 4 results in 256 triangles per
89 tile.
90
93 DISPLAY to get the default host and display number.
94 XENVIRONMENT
96 to get the name of a resource file that overrides the global
97 resources stored in the RESOURCE_MANAGER property.
98 XSCREENSAVER_WINDOW
100 The window ID to use with --root.
