This is the default. +.TP 8 +.B \-root +Draw on the root window. +.TP 8 +.B \-install +Install a private colormap for the window. +.TP 8 +.B \-visual \fIvisual\fP\fP +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. +.TP 8 +.B \-fps +Display the current frame rate, CPU load, and polygon count. +.TP 8 +.B \-trees \fInumber_of_trees\fP\fP +Specify how much trees are drawn in the landscape. +.TP 8 +.B \-count \fInumber_of_particles\fP\fP +Specify how much fire particles are drawn. A very special case is 0 +wich means that you get +.B rain +! +.TP 8 +.B \-size \fIviewport_size\fP\fP +Viewport of GL scene is specified size if greater than 32 and less than screensize. Default value is 0, meaning full screensize. +.TP 8 +.B \-texture +Show a textured ground and the trees. This is the default. +.TP 8 +.B \-no\-texture +Disables texturing the landscape. This implies that no trees are drawn. +.TP 8 +.B \-shadows +Show a shadow for each particle on the ground. This is the default. +.TP 8 +.B \-no\-shadows +Disables the drawing of the shadows. +.TP 8 +.B \-fog +Show a fog in the distance. +.TP 8 +.B \-no\-fog +Disables the fog. This is the default. +.TP 8 +.B \-wander +Move the observer around the landscape. This is the default. +.TP 8 +.B \-no\-wander +Keep the fire centered on the screen. +.TP 8 +.B \-trackmouse +Let the mouse be a joystick to change the view of the landscape. +This implies +.I \-no\-wander. +.TP 8 +.B \-no\-trackmouse +Disables mouse tracking. This is the default. +.TP 8 +.B \-wire +Draw a wireframe rendition of the fire: this will consist only of +single-pixel lines for the triangles. +.SH ENVIRONMENT +.PP +.TP 8 +.B DISPLAY +to get the default host and display number. +.TP 8 +.B XENVIRONMENT +to get the name of a resource file that overrides the global resources +stored in the RESOURCE_MANAGER property. +.SH SEE ALSO +.BR X (1), +.BR xscreensaver (1) +.SH COPYRIGHT +Copyright \(co 2001 by Eric Lassauge. +Permission to use, copy, modify, distribute, and sell this software and +its documentation for any purpose is hereby granted without fee, +provided that the above copyright notice appear in all copies and that +both that copyright notice and this permission notice appear in +supporting documentation.
