Geometry.LookupTable.Lookup1

Description

One-dimensional lookup tables

Synopsis

Documentation

Vector-based lookup table. Functions assume that values must increase with vector index, enabling binary search.

Constructors

LookupTable1 (Vector (a, b))

Find a value in the lookup table using binary search, interpolating linearly around the search result. Clips for out-of-range values.

Lookup in the LUT, with bias towards the left, i.e. when searching a value not present in the LUT, return the closest one before.
