mirrorblob — Draws a wobbly blob that distorts the image behind it.

Synopsis

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]

Description

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.

Options

-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.

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.
