Programme Notes:

Space Info Feedback is a modified version of SpOb Feedback which connected the output of a "Space Object" to the input in various ways. The modification in Space Info Feedback consists of the use of an informational "flag" to signal when a parameter equals or exceeds the pernitted maximum or is equal or is lower than the minimum. This allows a incremental and coordinated scan through the parameter space in either dimension (i.e. giving precedence to either the X or the Y parameter when incrementing).

As before, the internal variables are also represented in graphic form.

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:

(when programme is running, right mouse click on the image area to make the control panel visible)

"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

"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

"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

"Feedback"

(Set Feedback source)

"Source A"       -Selects the feedback source for parameter A:
"A Maxval.pos " -current position for maxval
"A Val.pos"           -current position for val
"A Minval.pos"    -current position for minval

"Source A in" -Selects the parameter to be used

"A"       -Selected variable is in A
"B"       -Selected variable is in B

"Source B"    -Selects the feedback source for parameter B:
"B Maxval.pos " -current position for maxval
"B Val.pos"         -current position for val
"B Minval.pos"    -current position for minval

"Source B in"

"A"       -Selected variable is in A
"B"       -Selected variable is in B

"AMP TYPE"

(Set Amp type)
   "Feedback type A"     -Selects type of output from Amplifier A

"normal"    -nomal output
"inverse"                           -inverted output (current value is subtracted from maximum value)

"Feedback type B"    -Selects type of output from Amplifier A
"normal"    -nomal output
"inverse"                           -inverted output (current value is subtracted from maximum value)

"Amp type A"              -Selects function mode for Amplifier A

"AvAmp"                           -Amplitude and Shift ranges are both 100% and the resulting values averaged
"AmpShift"    -Amplitude range is selected first and Shift range is a percentage of the remainder
"ShiftAmp" -Shift range is selected first and Amplitude range is a percentage of the remainder

"Amp type B"            -Selects function mode for Amplifier B
"AvAmp"                         -Amplitude and Shift ranges are both 100% and the resulting values averaged
"AmpShift" -Amplitude range is selected first and Shift range is a percentage of the remainder
"ShiftAmp"    -Shift range is selected first and Amplitude range is a percentage of the remainder

"AMP LEVELS A"

(Set Feedback levels amp A)

   "amp A"                       (range 0 -> 100)     -Sets the amplitude value for Amplifier A

   "shift A"    (range 0 -> 100) -Sets the shift value for Amplifier A

"AMP LEVELS B"

(Set Feedback levels amp B)

"amp B"                       (range 0 -> 100)     -Sets the amplitude value for Amplifier B

"shift B"    (range 0 -> 100) -Sets the shift value for Amplifier B

"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
