NAME
glforestfire - draws a GL animation of sprinkling fire-like 3D triangles
SYNOPSIS
glforestfire [-display host:display.screen] [-window] [-root] [-visual visual] [-delay microseconds] [-count number_of_particles] [-trees number_of_trees] [-size viewport_size] [-texture] [-no-texture] [-shadows] [-no-shadows] [-fog] [-no-fog] [-wireframe] [-no-wireframe] [-wander] [-no-wander] [-trackmouse] [-no-trackmouse] [-fps] [-no-fps]
DESCRIPTION
The glforestfire program draws an animation of sprinkling fire-like 3D triangles in a landscape filled with trees.
OPTIONS
glforestfire 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 triangles.
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_MANAGER property.
