DESCRIPTION
The glforestfire program draws an animation of sprinkling
fire-like 3D triangles in a landscape filled with trees.
OPTIONSglforestfire accepts the following options:
-window Draw on a newly-created window. This is the
default.
-root Draw on the root window.
-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.
-fps Display a running tally of how many frames per
second are being rendered. In conjunction with
-delay 0, this can be a useful benchmark of your
GL performance.
-trees number_of_trees
Specify how much trees are drawn in the landscape.
-count number_of_particles
Specify how much fire particles are drawn. A very
special case is 0 wich means that you get rain !
-size viewport_size
Viewport of GL scene is specified size if greater
than 32 and less than screensize. Default value is
0, meaning full screensize.
-texture
Show a textured ground and the trees. This is the
default.
-no-texture
Disables texturing the landscape. This implies
that no trees are drawn.
-shadows
Show a shadow for each particle on the ground.
This is the default.
-no-shadows
Disables the drawing of the shadows.
-fog Show a fog in the distance.
-no-fog Disables the fog. This is the default.
-wander Move the observer around the landscape. This is
the default.
-no-wander
Keep the fire centered on the screen.
-trackmouse
Let the mouse be a joystick to change the view of
the landscape. This implies -no-wander.
-no-trackmouse
Disables mouse tracking. This is the default.
-wire Draw a wireframe rendition of the fire: this will
consist only of single-pixel lines for the trian
gles.
ENVIRONMENT
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_MAN
AGER property.

rain).
