Programme Notes:

SpObDemo demonstrates a "Space Object"  in which the previous MetaParob has been expanded to cover systems where there is more than one parameter that changes: For example: the two dimensions (X,Y) of Cartesian space -or the three dimensions (RGB) of colour space.

In this case, a two parameter (dimensional) space has been used. This 2-D space is graphically represented in the same way as in the MetaParam Demo. However the same space is also interpreted in terms of both Cartesian and Polar  coordinates: One version using lines that connect the current location with the previous one -and one version that uses a dot to record only the current location. In both representations use a separate (but identical) colour system to keep the image readable by making sure that no line or dot drawn has the same colour as the previous one drawn at that location.

As with the previous "Demos" a right mouse click on the image area will make the control panel visible -so the user may experiment with the variables presented in the menu.

  

The menu options:

"Speed"
       (Set Process speed)

"delay"           -allows the image production to to speeded up or slowed down from 1 to 200 milliseconds
 "On/Off"        -gives the choice:

"run"         -allows the process to run
"pause"     -allows the process to pause

"Steps"
     (Set param increments)

"Val-A  inc"            (range 0 -> 100)     -Sets the A parameter increment
"Val-B inc"             (range 0 -> 100)     -Sets the B parameter increment

"Meta-Steps-A"
     (Set Upper Meta-Param increments)

"Maxval-A inc"  (range  0 -> 100)     -Sets the A "maximum" meta-parameter increment
"Minval-A inc"  (range  0 -> 100)     -Sets the A "minimum" meta-parameter increment

"Meta-Steps-B"
     (Set Lower Meta-Param increments)

"Maxval-B inc"  (range  0 -> 100)     -Sets the B "maximum" meta-parameter increment
"Minval-B inc"  (range  0 -> 100)     -Sets the B "minimum" meta-parameter increment

"Space"
     (Set action on exceeding Param Range)

"Spacesw-A"       -gives the choice for parameter A:

"wrap"                 -Value "wraps around" to opposite limit
"bounce"             -Value "bounces" back from exceeded limit
"snapwrap"         -Value "snaps" to opposite limit
"snapbounce"     -Value "snaps" to exceeded limit

"Spacesw-B"       -gives the choice for parameter B:

"wrap"                 -Value "wraps around" to opposite limit
"bounce"             -Value "bounces" back from exceeded limit
"snapwrap"         -Value "snaps" to opposite limit
"snapbounce"     -Value "snaps" to exceeded limit

"Initialisation"
     (Reset Start condition)

"Val-A init"              -Initialises parameter A to following:

"Min"              -Minimum limit of Parameter
"Max"              -Maximum limit of Parameter
"Middle"         -Middle of parameter range
"Random"      -Random value within parameter range

"Val-B init"              -Initialises parameter B to following:

"Min"              -Minimum limit of Parameter
"Max"              -Maximum limit of Parameter
"Middle"         -Middle of parameter range
"Random"      -Random value within parameter range

"Flow"
     (clear image or reset process)

"Process/Image"

"Clear"       -Removes Existing Image without resetting process
"RESET"    -Removes Existing Image and resets process
