sample_table()

double MayaFlux::Kinesis::sample_table ( std::span< const double >  table, double  t  )

inlinenoexcept

Read an evenly spaced table at a position in [0, 1], interpolating linearly.

Parameters

table	Samples spread evenly from position 0 (first) to 1 (last)
t	Position, clamped to [0, 1]

Returns

Interpolated value; zero for an empty table, the entry for a single one

The lookup under TimeMaps::piecewise_linear and the table kernels in Discrete/Kernels.
