NAME
topblock - a 3D world of falling blocks that build up and up.

SYNOPSIS
topblock [-display host:display.screen] [-visual visual] [-window] [-root] [-delay number] [-wireframe] [-fps] [-size number] [-spawn number] [-camX number] [-camY number] [-camZ number] [-rotate] [-no-carpet] [-no-nipples] [-blob] [-rotateSpeed number] [-follow] [-maxFalling number] [-resolution number] [-maxColors number] [-dropSpeed number] [-override]

DESCRIPTION
Creates a world of falling blocks that build up and up.

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.

-delay number
    Per-frame delay, in microseconds. Default: 10000 (0.01 seconds.).

-wireframe | -no-wireframe
    Render in wireframe instead of solid.

-fps
    Display the current frame rate, CPU load, and polygon count.

-size number
    Size of the base/carpet.

-spawn number
    Likeyhood of a new block being created per frame : 1 high, 1000 very low.

-camX number
    Initial camera X location in the world.

-camY number
    Initial camera Y location in the world.

-camZ number
    Initial camera Z location in the world.

-rotate | -no-rotate
    Add/Remove rotation to/from the animation.

-no-carpet
    Remove the base/carpet.

-no-nipples
    Remove nipples on the blocks (also applies to udders) (has no effect in blob mode).

-blob
    Run in blob mode, blocks become over sized spheres.

-rotateSpeed number
    Varries speed of world rotation.

-follow
    Camera follows blocks as they fall instead of camera being semi static (stays with top block).

-maxFalling number
    Maximum number of objects created before recycling occurs.

-resolution number
    Resolution of tubes, disks and spheres.

-maxColors number
    Number of different colors available to falling objects.

-dropSpeed number
    Varries speed of falling objects.

-override
    Overrides camera settings and provides a tunnel view.

KEYS

a   Increases viewing X coordinate.

z   Decreases viewing X coordinate.

s   Increases viewing Y coordinate.

x   Decreases viewing Y coordinate.

d   Increases viewing Z coordinate.

c   Decreases viewing Z coordinate.

f   Increases camera location X coordinate.

v   Decreases camera location X coordinate.

g   Increases camera location Y coordinate.

b   Decreases camera location Y coordinate.

h   Increases camera location Z coordinate.

n   Decreases camera location Z coordinate.

r   Increases world rotation.

q   quit.

EXAMPLES
To see which block follow-mode is tracking, set the number of block colors to 1.

topblock -follow -maxColors 1

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.
