PosiStageNet CHOP
Summary[edit]
This operator decodes PosiStageNet protocol data into CHOP channels. PosiStageNet will track any number of objects and output their position, orientation, speed, acceleration, or the objects' target position.
PosiStageNet is a data exchange protocol created by VYV and MA Lighting, and has applications in on-stage lighting, sound, and projection mapping.
See also BlackTrax CHOP.
Parameters - Setup Page
Active active - If turned off, the PosiStageNet CHOP will stop receiving data.
Network Address netaddress - Set this parameter to the network address of the PosiStageNet server, device, or software.
Port port - By default, TCP Port uses 56565. Firewall settings may need to be adjusted to allow for the PosiStageNet CHOP to communicate properly.
Sample Rate samplerate - Specify the rate at which the incoming data is sampled.
Position pos - Include position channels.
Orientation ori - Include orientation channels as Euler angles.
Speed speed - Include speed channels.
Acceleration accel - Include acceleration channels.
Target Position targetpos - Include the target position as channels.
Reset Pulse resetpulse - This button resets the channels. This will clear all the data channels in the CHOP, so any untracked data will be removed
Parameters - Common Page
Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
Export Method exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such hasgeo1/transform1:tx.
Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).

An Operator Family which operate on Channels (a series of numbers) which are used for animation, audio, mathematics, simulation, logic, UI construction, and many other applications.
samples-per-second of a CHOP. Each CHOP in your network has a sample rate, whether it is used or not. The overall timeline has a "frame rate", which is the number of animation frames per second, generally your monitor display frequency.
To pulse a parameter is to send it a signal from a CHOP or python or a mouse click that causes a new action to occur immediately. A pulse via python is via the .pulse() function on a pulse-type parameter, such as Reset in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in a channel.
A Time Slice is the time from the last cook frame to the current cook frame. In CHOPs it is the set of short channels that only contain the CHOP channels' samples between the last and the current cook frame.
A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator.
Exporting is the connection of CHOP channels to parameters of operators. The output of each exporting CHOP is one or more channels, active only while the CHOP Viewer is on. The current value of a channel can be exported to a parameter of any operator, overriding that parameter's value. See Parameter.
An Operator Family that manipulates text strings: multi-line text or tables. Multi-line text is often a command Script, but can be any multi-line text. Tables are rows and columns of cells, each containing a text string.
Parameters in TouchDesigner are an operator's settings (numbers, menus, flags, strings, paths) which the user can alter. Parameters for any operator can be opened by right-clicking on the operator and selecting "Parameters..." A currently selected operator's parameters can be viewed in a Network Editor by pressing the keyboard shortcut 'p'.
TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply /. A typical path is /project1/moviein1.
