32 The \fIglforestfire\fP program draws an animation of sprinkling fire-like 3D triangles in
33 a landscape filled with trees.
36 accepts the following options:
39 Draw on a newly-created window. This is the default.
42 Draw on the root window.
45 Install a private colormap for the window.
47 .B \-visual \fIvisual\fP\fP
48 Specify which visual to use. Legal values are the name of a visual class,
49 or the id number (decimal or hex) of a specific visual.
52 Display the current frame rate, CPU load, and polygon count.
54 .B \-trees \fInumber_of_trees\fP\fP
55 Specify how much trees are drawn in the landscape.
57 .B \-count \fInumber_of_particles\fP\fP
58 Specify how much fire particles are drawn. A very special case is 0
59 wich means that you get
63 .B \-size \fIviewport_size\fP\fP
64 Viewport of GL scene is specified size if greater than 32 and less than screensize. Default value is 0, meaning full screensize.
67 Show a textured ground and the trees. This is the default.
70 Disables texturing the landscape. This implies that no trees are drawn.
73 Show a shadow for each particle on the ground. This is the default.
76 Disables the drawing of the shadows.
79 Show a fog in the distance.
82 Disables the fog. This is the default.
85 Move the observer around the landscape. This is the default.
88 Keep the fire centered on the screen.
91 Let the mouse be a joystick to change the view of the landscape.
96 Disables mouse tracking. This is the default.
99 Draw a wireframe rendition of the fire: this will consist only of
100 single-pixel lines for the triangles.
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.
