16 Flies through height maps, optionally animating the instantiation and
17 destruction of generated tiles; by default, tiles 'grow' into place
18 (height gradually increased up to correct value). In windowed mode the
19 following key controls are available:
20 left, right
22 Turn left and right.
23 a,w,s,d Move left, forwards, backwards, and to the right, respectively.
25 1,2 Decrease and increase manual speed, respectively.
27 Spacebar
29 Return to automatic control.

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