Phaser POP

Summary

The Phaser POP works like the Phaser CHOP. It does staggered (time-offset) animation interpolation on a POP attribute. Phaser outputs one new attribute Phaser. Each point animates Phaser from 0 to 1 over a cycle, but each point's value rises from 0 and arrives at 1 at different times.

The Output Attribute Scope Phase can be used to blend or animate other attributes downstream. Phase is multi-component if the Phase Attribute Scope is multi-component.

The Fraction parameter is by default clamped between 0 and 1. The Extend Input menu lets you control Fraction with numbers below 0 and above 1 with different effect. When Fraction goes above 1:

• Clamp - default and current behavior - the values hold.
• Cycle - the Phaser goes back to its 0 state and cycles the input time 0-1
• Mirror - the Phaser fully reverses and zig-zags the input time between 0-1
• Mirror Slope - the first sample starts decreasing first after the input time goes above 1
• Add - the Phaser outputs values that keep increasing when the input time goes beyond 1

Attributes make up the numeric data blocks of POPs. Each POPs has three blocks of data: a Point List which includes the P point Position attribute, a Primitive List and a Vertex List, and each are made of any number of attributes.

A parameter in most CHOPs that restricts which channels of that CHOP will be affected. Normally all channels of a CHOP are affected by the operator. TOPs have Channel Mask, a similar feature.

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.

A surface type in POPs and 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.

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.

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.
