25 Flies through height maps, optionally animating the instantiation and
26 destruction of generated tiles; by default, tiles 'grow' into place (height
27 gradually increased up to correct value). In windowed mode the following key
28 controls are available:
34 Move left, forwards, backwards, and to the right, respectively.
37 Decrease and increase manual speed, respectively.
40 Return to automatic control.
43 accepts the following options:
46 Draw on the root window.
49 Draw on a newly-created window. This is the default.
52 Install a private colormap for the window.
54 .B \-visual \fIvisual\fP
55 Specify which visual to use. Legal values are the name of a visual
56 class, or the id number (decimal or hex) of a specific visual.
58 .B \-delay \fImicroseconds\fP
59 Delay between frames; default 20000 (1/50th of a second).
62 Display the current frame rate, CPU load, and polygon count.
65 Use all possible methods to animate tile instantiation.
68 Do not animate instatiation at all; use this to get standard landscape
72 Drawable window region has a 16:9 aspect ratio, regardless of actual
79 Flat shading (OpenGL will use one color per primitive, rather than
80 interpolating betwixt vertices).
86 Do not display 'water' (forces negative values to zero, and selects a
87 different coloring method).
89 .B \-visibility \fIfloat\fP
90 Value in range [0.2,1.0] (default 0.6) specifying proportion of viewable
91 XY plane which is to be drawn upon.
93 .B \-color \fIstring\fP
94 Selects color scheme. Use with no or bogus argument for current list.
96 .B \-nsubdivs \fIinteger\fP
97 Number of times to recursively subdivide each triangular tile. Each
98 increment increases total triangles by a factor of 4; for instance the default
99 setting 4 results in 256 triangles per tile.
105 to get the default host and display number.
108 to get the name of a resource file that overrides the global resources
109 stored in the RESOURCE_MANAGER property.
