The Graphics Processing Unit. This is the high-speed, many-core processor of the graphics card/chip that takes geometry, images and data from the CPU and creates images and processed data.
A built-in panel in TouchDesigner that contains a library of components and media that can be dragged-dropped into a TouchDesigner network.
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.
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 from a CHOP is typically a 0 to 1 to 0 signal in a channel, and a pulse via python is via a
.pulse() call on a pulse-type parameter, such as Reset in a Speed CHOP.
Each SOP has a list of Points. Each point has an XYZ 3D position value plus other optional attributes. Each polygon Primitive is defined by a vertex list, which is list of point numbers.
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.
TouchDesigner is a hierarchy of components. "root" is the top-most network in the hierarchy. The Path is simply
/. A typical path is
A custom interactive control panel built within TouchDesigner. Panels are created using Panel Components whose look is created entirely with TOPs.
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'.
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.
OP Snippets is a set of numerous examples of TouchDesigner operators, which you access via the Help menu. These can be copied/pasted into your projects.
An Operator Family that reads, creates and modifies 3D polygons, curves, NURBS surfaces, spheres, meatballs and other 3D surface data.
A 3D image created with the Render TOP. Also used more generally to include the compositing (with TOPs) to generate an output image.
The connection of an output of one node to the input of another node in a network. In contrast, see Link.
The OpenGL code that creates a rendered image from polygons and textures. Shaders can be made of up to three parts: Vertex Shader, Geometry Shader and/or Pixel Shader, which are either embedded inside Materials, or placed in Text DATs and referenced to a GLSL Material.
A text string that contains data (string, float, list, boolean, etc.) and operators (+ * < etc) that are evaluated by the node's language (python or Tscript) and returns a string, float list or boolean, etc. Expressions are used in parameters, DATs and in scripts.
TOuch Environment file, the file type used by TouchDesigner to save your project.
