Detailed Description

CCurve transfer-curve component with its preset, evaluation, and LUT helpers.

Data and pure functions only; the point-dragging widget lives in rigVectorEditor.

Function Documentation

applyPreset()

void rigkit::curve::applyPreset ( ecs::CCurve & c, ecs::CCurve::Preset p )

inline

Replace points from a named preset (Custom is a no-op).

Linear uses linear interpolation, so the diagonal is a straight line. The other presets use smooth interpolation. Handles are cleared.

solveBezierS()

float rigkit::curve::solveBezierS ( float ax, float c1x, float c2x, float bx, float t )

inline

Solve cubic Bezier x(s) = t for s in [0,1].

Newton with bisection clamp.
