Flies through height maps, optionally animating the instantiation
and destruction of generated tiles; by default, tiles 'grow' into place
(height gradually increased up to correct value). In windowed mode the
following key controls are available:
- left, right
- Turn left and right.
- a,w,s,d
- Move left, forwards, backwards, and to the right, respectively.
- 1,2
- Decrease and increase manual speed, respectively.
- Spacebar
- Return to automatic control.
crackberg accepts the following options:
- -root
- Draw on the root window.
- -window
- Draw on a newly-created window. This is the default.
- -install
- Install a private colormap for the window.
- -visual
visual
- Specify which visual to use. Legal values are the name of a visual class,
or the id number (decimal or hex) of a specific visual.
- -delay
microseconds
- Delay between frames; default 20000 (1/50th of a second).
- -fps
- Display the current frame rate, CPU load, and polygon count.
- -crack
- Use all possible methods to animate tile instantiation.
- -boring
- Do not animate instatiation at all; use this to get standard landscape
generator behavior.
- -letterbox
- Drawable window region has a 16:9 aspect ratio, regardless of actual
window size.
- -lit
- Enable lighting.
- -flat
- Flat shading (OpenGL will use one color per primitive, rather than
interpolating betwixt vertices).
- -wire
- Wireframe.
- -nowater
- Do not display 'water' (forces negative values to zero, and selects a
different coloring method).
- -visibility
float
- Value in range [0.2,1.0] (default 0.6) specifying proportion of viewable
XY plane which is to be drawn upon.
- -color
string
- Selects color scheme. Use with no or bogus argument for current list.
- -nsubdivs
integer
- Number of times to recursively subdivide each triangular tile. Each
increment increases total triangles by a factor of 4; for instance the
default setting 4 results in 256 triangles per tile.
- DISPLAY
- to get the default host and display number.
- XENVIRONMENT
- to get the name of a resource file that overrides the global resources
stored in the RESOURCE_MANAGER property.
