Detailed Description

template<class V, class T = float>
struct oe::util::Curve< V, T >

General purpose curve (can be used for gradients, animations, etc...)

Example with an int

oe::util::Curve<int32_t> curve({
      {.position = 0.0, .value = 10, .interpolation = CurveInterpolation::LINEAR},
      {.position = 0.5, .value = 22, .interpolation = CurveInterpolation::DIRECT},
      {.position = 0.8, .value = 22, .interpolation = CurveInterpolation::HOLD_LAST},
      {.position = 1.0, .value = 14, .interpolation = CurveInterpolation::LINEAR},
});
 
int32_t value_at_first_quartile = curve.eval(0.25);

You can use any type for V, but you need to make sure the class overloads operators addition between objects and multiplication with a float

Note

It is assumed the vector is filled with ascending point position
