Attributes Class

An Attributes object describes a set of Prim Class, Point Class, or Vertex Class attributes, contained within a SOP.

Members

owner → OP (Read Only):

The OP to which this object belongs.

Methods

[name]→ Attribute:

Attributes can be accessed using the [] subscript operator.

• name - The name of the attribute.

attribs = scriptOP.pointAttribs # get the Attributes object
normals = attribs['N']

create(name, default)→ Attribute:

Create a new Attribute.

• name - The name of the attribute.
• default - (Optional) Specify default values for custom attributes. For standard attributes, default values are implied.

Standard attributes are: N (normal), uv (texture), T (tangent), v (velocity), Cd (diffuse color).

# create a Normal attribute with implied defaults.
n = scriptOP.pointAttribs.create('N')

# set the X component of the first point's Normal attribute.
scriptOp.points[0].N[0] = 0.3 

# Create a Vertex Attribute called custom1 with defaults set to (0.0, 0.0)
n = scriptOP.vertexAttribs.create('custom1', (0.0, 0.0) )

# Create a Primitive Attribute called custom2 defaulting to 1
n = scriptOP.primAttribs.create('custom2', 1 )

Information associated with SOP geometry. Points and primitives (polygons, NURBS, etc.) can have any number of attributes - position (P) is standard, and built-in optional attributes are normals (N), texture coordinates (uv), color (Cd), etc.

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.

A sequence of vertices form a Polygon in a SOP. Each vertex is an integer index into the Point List, and each Point holds an XYZ position and attributes like Normals and Texture Coordinates.

A surface type in SOPs that includes polygon, curve (NURBS and Bezier), patch (NURBS and Bezier) and other basic shapes like sphere, tube and metaball. Points and Primitives are part of the Geometry Detail, which is a part of a SOP.
