Mapping POP Attributes to Parameters

On some parameters of some POPs, you can have a different parameter value for each point of the POP. Some POPs let you map one of its Attributes to a parameter via a Map page on the parameter dialog.

For example, on the Transform POP's Map page, you can choose an attribute or a component of an attribute, and map the values of that attribute to a parameter, giving a different value for each point.

The Combine Operation menu lets you choose how to combine the attribute value with the parameter value you set in the OP dialog - you can Add them, Multiply them, or ignore the value in the parameter and Set it to the attribute value alone.

Using Sequential Blocks, you can map multiple attributes to multiple parameters.

Each block has a menu for possible attributes and a menu for acceptable parameters to map to. You can also get attributes from any of the inputs (_in0 by default)

Mapping POP Attributes to Parameters

POPs (Point Operators) is a new Operator Family of TouchDesigner that runs on the GPU accelerated graphics card or chips, and creates/modifies 3D data which is rendered by the Render TOP or passed to devices like DMX lighting, LED arrays, lasers or other external systems.

Attributes are data associated with POP geometry. Points, Vertex (Vertices) and Primitives (polygons, lines, etc) can have any number of attributes.
