Box POP

Summary

The Box POP creates 6-sided boxes. The box can have 8 points - one at each corner with each face sharing a point with two other faces. Or the box can have 24 points with each of the 6 faces using 4 unique points (Unique Points toggle parameter).

Where the box has 8 points, the user can choose to have vertex normals or primitive normals, which renders the cube "faceted" (flat-looking). Or the user can choose point normals (or no normals) which will make corners look non-faceted.

The Connectivity menu allows for no primitives to be output (just points) (None), or the points connected with 4-point Quadrelaterals (quads) or 3-point Triangles, or output one Point Primitive for every point.

The box can have optional rounded corners with control over radius and the amount of subdivision at the corners.

Tip: To subdivide the faces send the Box POP to a Subdivide POP with Crease Weight 1.

Texture coordinates can be created with different placement - per-face, or one cube map that is wrapped over all the faces, etc. Point or vertex colors can be applied.

The Anchor parameters can shift the lower or upper side of the box to X=0, Y=0, Z=0. The box can be post-translated/rotated.

• Quadrilaterals quads -

Unique Points uniquepoints - Enable not sharing points between primitives.

Modify Bounds modifybounds - Available only when an input is connected to the POP to set bounds for the POP. When Modify Bounds is On the parameters below will further modify the shape of the POP.

Parameters - Common Page

Bypass bypass - Pass through the first input to the output unchanged.

Free Extra GPU Memory freeextragpumem - Free memory that has accumulated when output memory has grown and shrunk.

Delete Input Attributes delinputattrs - Only output which attributes you specify in this POP - helps isolate attributes into a separate branch.

TouchDesigner Build: Latest\nwikieditor2025.30000

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.

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.

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.

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.

An operator whose Bypass flag is set does nothing: All data going into its first input appears at its output unaffected.

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.

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

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.
