twist~
Description
The twist~ object accepts a ramp between 0 and 1 (such as one generated by phasor~) and produces a piecewise linear approximation of an expoential function using the same algorithm as the curve~ object. The curvature of the ramp is controlled by the curve attribute that ranges from -1 to 1. A curve value of 0 produces an output ramp identical to the input.
Arguments
None.
Attributes
curve [float]
The curve attribute sets the parameters of the exponential function that generates the non-linear output. It can range between -1 and 1. For ascending ramps, values of curve less than 1 produce values above the linear input and values of curve greater than 1 produce values below the linear input. As curve values near -1 or 1, the curavture becomes more extreme.
interval [int]
The curved output is a piecewise linear approximation of the exponential function. The interval attribute sets the number of samples used for each line segement. Values of interval must be a power of 2 between 2 and 64 samples. Larger values will produce a less accurate approximation but could be more efficient. If the signal vector size is less than interval, the actual segment length will be the signal vector size.
Possible values:
'2'
(
2 sample segment length
)
'4'
(
4 sample segment length
)
'8'
(
8 sample segment length
)
'16'
(
16 sample segment length
)
'32'
(
32 sample segment length
)
'64'
(
64 sample segment length
)
shapemode [int]
The shapemode attribute, when enabled, causes descending ramps to be symmetrical with ascending ramps. shapemode is enabled by default.
syncupdate [int]
When enabled syncupdate defers changes to the curve attribute until either an input ramp starts or changes direction (resets). This avoids discontinuities in the ramp output.
Common Box Attributes
annotation [symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.
background [int] (default: 0)
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.
color [4 floats]
Sets the color for the object box outline.
fontface [int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname [symbol]
Sets the object's font.
fontsize [float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'64'
'72'
hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
hint [symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick [int] (default: 0)
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile [symbol]
JS Painter File
patching_rect [4 floats] (default: 0. 0. 100. 0.)
Sets the position and size of the object in the patcher window.
position [2 floats]
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation [int] (default: 0)
Sets whether an object belongs to the patcher's presentation.
presentation_rect [4 floats] (default: 0. 0. 0. 0.)
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect [4 floats]
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size [2 floats]
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor [4 floats]
Sets the color for the object's text in RGBA format.
textjustification [int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname [symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.
