Detailed Description

A mode shape sampled on a uniform grid across the object's normalized extent [0, 1], mode-major.

Physically this is phi_m(x): how strongly position x couples to mode m. It is sampled rather than analytic because a spec has to be able to carry a measured shape as easily as an ideal one. An empty map means position has no effect and every mode couples with weight 1 — which is also the state that preserves authored gains verbatim.

Member Function Documentation

empty()

bool pulp::signal::ModalShapeMap::empty ( ) const

inline

weight_at()

float pulp::signal::ModalShapeMap::weight_at ( int mode, float position ) const

inline

Linearly interpolated weight of mode at normalized position.

position is clamped to [0, 1]; an empty map returns 1.

Member Data Documentation

grid_points

int pulp::signal::ModalShapeMap::grid_points = 0

Samples per mode across [0, 1]. Zero means "no map".

weights

std::vector<float> pulp::signal::ModalShapeMap::weights

grid_points weights per mode, laid out [mode * grid_points + g].
