Overview
The gflux program draws a colourfull animated rippling square rotating in 3D space.
Options
gflux 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.
-
-squares num -
Specifies the size of the grid in squares. default 19
-
-resolution num -
Specifies the wireframe detail of the squares. default 4
-
-draw num -
Specifies the draw method. 0 = wireframe, 1 = solid, 2 = light (default), 3 = checker texture mapped, 4 = PNM image is read from stdin and mapped to the surface
-
-flat num -
0 for smooth shading 1 for flat. default 0
-
-speed num -
Specifies speed of ripples flowing over the surface. default 0.05
-
-rotationx num -rotationy num -rotationz num -
Specifies the speed of rotation of the surface in these axis
-
-waves num -
Specifies the number of ripple centres at any one time. Values should be greater than 1. default 3
-
-waveChange num -
Specifies the duration of a ripple centre. after this they fade away to be reborn elsewhere with a different frequency. default 50
-
-waveHeight num -
Specifies the height of ripples on the surface. default 1.0
-
-waveFreq num -
Specifies the maximum frequency of ripples. default 3.0
-
-zoom num -
Specifies the size of the viewport. Smaller values fill the screen with rippling surface. default 1.0
-
-delay microseconds -
How long to pause between frames. Default is 20000, or 0.02 second.
-
-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.
Environment
-
XENVIRONMENT -
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
