mirrorblob - Draws a wobbly blob that distorts the image behind it.
mirrorblob [-display host:display.screen] [-visual visual] [-window] [-root] [-wire] [-delay number] [-fog] [-walls] [-colour] [-texture] [-offset-texture] [-blend] [-antialias] [-resolution number] [-bumps number] [-fade-time number] [-hold-time number] [-zoom number] [-fps]
Draws a wobbling blob, making use of alpha blending, fog, textures, and lighting, plus a ``frames per second'' meter so that you can tell how fast your graphics card is... Requires OpenGL.
-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. -window Draw on a newly-created window. This is the default. -root Draw on the root window. -wire Render in wireframe instead of solid. -delay number Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.). -fog | -no-fog Whether to enable fog. -walls | -no-walls Add walls for blob to hit. -colour | -no-colour Draw coloured blob. If also textured, the texture will have color mixed in. -texture | -no-texture Whether to wrap a texture image on the blob. -offset_texture | -no-offset_texture Whether to ofset the texture calculations to only use a region of the image under the blob. This works well with a semi-transparent blob. -blend | -no-blend Whether to draw a transparent blob. (see also offset_texture above) -antialias | -no-antialias Whether to antialias lines. -resolution number Resolution of the tessellation used to calculate and draw the blob. Larger numbers give a smoother blob but increase calculation times exponentially. -bumps number Number of bumps used to distort the blob. -hold-time number Time until loading a new image. -fade-time number Time taken to transition between images. -zoom number Size multiplier for blob. -fps Display the current frame rate, CPU load, and polygon count.
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.
