NAME
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. | |
