Shared Mem Out COMP

Summary

NOTE

License: Only available in TouchDesigner Educational, TouchDesigner Commercial and TouchDesigner Pro.

The Shared Mem In TOP is only available in TouchDesigner Commercial and Pro.

The Shared Mem Out COMP will write transform data to a shared memory block. This memory block can be read by another Touch process using the Shared Mem In COMP.

sharedmemoutCOMP_Class

Parameters - Setup Page

Active active - Controls if this node cooks every frame or not.

Shared Mem Name name - The name of the memory block it writes to.

Parameters - Extensions Page

The Extensions parameter page sets the component's python extensions. Please see extensions for more information.

Extension ext - Sequence of info for creating extensions on this component

Object ext0object - A number of class instances that can be attached to the component.

Name ext0name - Optional name to search by, instead of the instance class name.

Promote ext0promote - Controls whether or not the extensions are visible directly at the component level, or must be accessed through the .ext member. Example: n.Somefunction vs n.ext.Somefunction

Re-Init Extensions reinitextensions - Recompile all extension objects. Normally extension objects are compiled only when they are referenced and their definitions have changed.

Parameters - Common Page

The Common parameter page sets the component's node viewer and clone relationships.

Parent Shortcut parentshortcut - Specifies a name you can use anywhere inside the component as the path to that component. See Parent Shortcut.

Global OP Shortcut opshortcut - Specifies a name you can use anywhere at all as the path to that component. See Global OP Shortcut.

Internal OP iop - Sequence header for internal operators.

Shortcut iop0shortcut - Specifies a name you can use anywhere inside the component as a path to "Internal OP" below. See Internal Operators.

OP iop0op - The path to the Internal OP inside this component. See Internal Operators.

Node View nodeview - ⊞ - Determines what is displayed in the node viewer, also known as the Node Viewer. Some options will not be available depending on the Component type (Object Component, Panel Component, Misc.)

• Default Viewer default - Displays the default viewer for the component type, a 3D Viewer for Object COMPS and a Control Panel Viewer for Panel COMPs.

• Operator Viewer opviewer - Displays the node viewer from any operator specified in the Operator Viewer parameter below.

Operator Viewer opviewer - Select which operator's node viewer to use when the Node View parameter above is set to Operator Viewer.

Enable Cloning enablecloning - Control if the OP should be actively cloneing. Turning this off causes this node to stop cloning it's 'Clone Master'.

Enable Cloning Pulse enablecloningpulse - Instantaneously clone the contents.

Clone Master clone - Path to a component used as the Master Clone.

Load on Demand loadondemand - Loads the component into memory only when required. Good to use for components that are not always used in the project.

Enable External .tox enableexternaltox - When on (default), the external .tox file will be loaded when the .toe starts and the contents of the COMP will match that of the external .tox. This can be turned off to avoid loading from the referenced external .tox on startup if desired (the contents of the COMP are instead loaded from the .toe file). Useful if you wish to have a COMP reference an external .tox but not always load from it unless you specifically push the Re-Init Network parameter button.

Enable External .tox Pulse enableexternaltoxpulse - This button will re-load from the external .tox file (if present).

External .tox Path externaltox - Path to a .tox file on disk which will source the component's contents upon start of a .toe. This allows for components to contain networks that can be updated independently. If the .tox file can not be found, whatever the .toe file was saved with will be loaded.

Reload Custom Parameters reloadcustom - When this checkbox is enabled, the values of the component's Custom Parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

Reload Built-In Parameters reloadbuiltin - When this checkbox is enabled, the values of the component's built-in parameters are reloaded when the .tox is reloaded. This only affects top-level parameters on the component, all parameters on nodes inside the component are always reloaded with the .tox.

Save Backup of External savebackup - When this checkbox is enabled, a backup copy of the component specified by the External .tox parameter is saved in the .toe file. This backup copy will be used if the External .tox can not be found. This may happen if the .tox was renamed, deleted, or the .toe file is running on another computer that is missing component media.

Sub-Component to Load subcompname - When loading from an External .tox file, this option allows you to reach into the .tox and pull out a COMP and make that the top-level COMP, ignoring everything else in the file (except for the contents of that COMP). For example if a .tox file named project1.tox contains project1/geo1, putting geo1 as the Sub-Component to Load, will result in geo1 being loaded in place of the current COMP. If this parameter is blank, it just loads the .tox file normally using the top level COMP in the file.

Relative File Path Behavior relpath - ⊞ - Set whether the child file paths within this COMP are relative to the .toe itself or the .tox, or inherit from parent.

• Use Parent's Behavior inherit - Inherit setting from parent.

• Relative to Project File (.toe) project - The path, when specified as a relative path, will be relative to the .toe file.

• Relative to External COMP File (.tox) externaltox - The path, when specified as a relative path, will be relative to the .tox file. When no external COMP file is specified, or when Enable External .tox is not toggled on, this doesn't have any impact.

Info CHOP Channels

Extra Information for the Shared Mem Out COMP can be accessed via an Info CHOP.

Common COMP Info Channels

• num_children - Number of children in this component.

Common Operator Info Channels

• total_cooks - Number of times the operator has cooked since the process started.

• cook_time - Duration of the last cook in milliseconds.

• cook_frame - Frame number when this operator was last cooked relative to the component timeline.

• cook_abs_frame - Frame number when this operator was last cooked relative to the absolute time.

• cook_start_time - Time in milliseconds at which the operator started cooking in the frame it was cooked.

• cook_end_time - Time in milliseconds at which the operator finished cooking in the frame it was cooked.

• cooked_this_frame - 1 if operator was cooked this frame.

• warnings - Number of warnings in this operator if any.

• errors - Number of errors in this operator if any.

An Operator Family that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

An Operator Family that contains its own Network. There are sixteen 3D Object Component and ten 2D Panel Component types. See also Network Path.

Any component can be extended with its own Python classes which contain python functions and data.

The sub-Family of Component types that are used to define and render 3D scenes. A Geometry Component is an Object that contains the 3D shapes to render. A Camera COMP and Light COMP are other Object types. Separately, "Objects" also refers to Python objects.

A Parent Shortcut is a parameter on a component that contains a name that you can use anywhere inside the component to refer to that component using the syntax parent.Name, for example parent.Effect.width to obtain panel width.

A name for a component that is accessible from any node in a project, which can be declared in a component's Global Operator Shortcut parameter.

Any of the procedural data operators. OPs do all the work in TouchDesigner. They "cook" and output data to other OPs, which ultimately result in new images, data and audio being generated. See Node.

Operator shortcuts are Python objects that return operators (or sometimes parameters). These include Parent Shortcuts for accessing a component from within that component, and Global OP Shortcuts that access a unique component from anywhere in TouchDesigner.

An Operator Family that contains its own Network. There are sixteen 3D Object Component and ten 2D Panel Component types. See also Network Path.

The viewer of a node can be (1) the interior of a node (the Node Viewer), (2) a floating window (RMB->View... on node), or (3) a Pane that graphically shows the results of an operator.

A custom interactive control panel built within TouchDesigner. Panels are created using Panel Components.

Cloning makes multiple components match the contents of a master component. A Component whose Clone parameter is set will be forced to contain the same nodes, wiring and parameters as its master component. Cloning does not create new components as does the Replicator COMP.

To "pulse" a parameter is to send it a signal from (1) an exported CHOP channel or (2) a python command or (3) 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 parameter in a Speed CHOP. A pulse from a CHOP is typically a 0 to 1 to 0 signal in an exported channel.

The location of an operator within the TouchDesigner environment, for example, /geo1/circle1, a node called circle1 in a component called geo1. The path / is called Root. This path is displayed at the top of every Pane, showing which Component's network you are currently in. To refer instead to a filesystem folder, directory, disk file or http: address, see Folder.

TouchDesigner Component file, the file type used to save a Component of your TouchDesigner project.

TOuch Environment file, the file type used by TouchDesigner to save your entire project.

There are 2 kinds of parenting. The "parent component" is the component in which a node resides. The metaphor is extended to include grand parents, grand-grand parents, etc. The root / is the ultimate parent to all nodes. See also 3D Parenting and panel Parenting.

An Operator Family which operate on Channels (a sequence of numbers (Samples)) which are used for animation, audio, mathematics, simulation, logic, UI construction, and data streamed from/to devices and protocols.
