Glossary

Vertex

A point in space. Depending on the editing perspective, a vertex may exist in 2D, 4D, or 5D space.

Vertex Cube

A structure composed of up to 8 vertices, each of which lie at a corner of a cube, with dimensions time, key scale, and modulation. Deformer assignments are properties of the vertex cube structure. A single intercept path is associated with each vertex cube.

Intercept

The curve knot points that define all types of curves.

Line Intercept

One of the intercepts at the two poles of a polar dimension. The parameters of a line intercept are the weighted average of all the vertices of the vertex cube, at that pole.

Intercept Path

The path spanning between two line intercepts that an intercept follows over time. This is linear by default, but it may be distorted by a deformer.

Curve

The function that interpolates smoothly between intercept points.

Mesh

A set of vertices and vertex cubes.

Layer

The surface defined by a particular mesh. In waveshape and spectrum layers, intercept paths may not overlap in time. To model patterns that overlap, multiple layers must be used--one for each non-overlapping pattern.

Time Surface

The set of waveform (time-domain) layers. The mesh that embodies this surface has 5 spatial dimensions.

Spectrum Filter

This is the set of phase and amplitude layers that operate on the respective frequency domain spectra. The meshes that embody the amplitude and phase surfaces have 5 spatial dimensions. The 'filter' is not strictly subtractive; it can synthesize additively.

2D Editing Panel

Any of the editing panels that show 2 dimensional data: waveshape editor, harmonic spectrum editor, 2D envelope editor, waveshaper, impulse modeller, and deformer.

3D Editing Panel

An editor that displays data in 3 dimensions at once (x, y, colour). The three of these are the Spectrum Filter editor, Time Surface editor, and 3D Envelope editor.
