Enumeration Type Documentation

enum TsAntiRegressionMode

Modes for enforcing non-regression in splines.

See page_ts_regression for a general introduction to regression and anti-regression.

Enumerator
TsAntiRegressionNone	Do not enforce. If there is regression, runtime evaluation will use KeepRatio.
TsAntiRegressionContain	Prevent tangents from crossing neighboring knots. This guarantees non-regression, but is slightly over-conservative, preventing the authoring of some extreme curves that cannot be created without non-contained tangents.
TsAntiRegressionKeepRatio	If there is regression in a segment, shorten both of its tangents until the regression is just barely prevented (the curve comes to a near-standstill at some time). Preserve the ratio of the tangent lengths.
TsAntiRegressionKeepStart	If there is regression in a segment, leave its start tangent alone, and shorten its end tangent until the regression is just barely prevented. This matches Maya behavior.

Definition at line 272 of file types.h.

enum TsCurveType

Type of interpolation for a spline's Curve segments.

Enumerator
TsCurveTypeBezier
TsCurveTypeHermite

Definition at line 92 of file types.h.

enum TsExtrapMode

Curve-shaping mode for one of a spline's extrapolation regions (before all knots and after all knots).

Enumerator
TsExtrapValueBlock
TsExtrapHeld
TsExtrapLinear
TsExtrapSloped
TsExtrapLoopRepeat
TsExtrapLoopReset
TsExtrapLoopOscillate

Definition at line 101 of file types.h.

enum TsInterpMode

Interpolation mode for a spline segment (region between two knots).

Enumerator
TsInterpValueBlock
TsInterpHeld
TsInterpLinear
TsInterpCurve

Definition at line 82 of file types.h.

enum TsSplineSampleSource

The source for a particular part of a sampled spline. A TsSpline can have a number of different regions. The source is not important to the values that vary over time, but if the spline is sampled and displayed in a user interface, the source can be used to highlight different regions of the displayed spline.

Enumerator
TsSourcePreExtrap
TsSourcePreExtrapLoop
TsSourceInnerLoopPreEcho
TsSourceInnerLoopProto
TsSourceInnerLoopPostEcho
TsSourceKnotInterp
TsSourcePostExtrap
TsSourcePostExtrapLoop
