Return the interpolated value at position t.
- Parameters
-
t The position at which to evaluate the interpolator. Typically in the range [0,1].
- Returns
- The interpolated value.
Implemented in cgv::math::identity_interpolator< ValueT, ParamT >, cgv::math::discrete_interpolator< ValueT, ParamT >, cgv::math::uniform_linear_interpolator< ValueT, ParamT >, cgv::math::linear_interpolator< ValueT, ParamT >, cgv::math::uniform_smooth_interpolator< ValueT, ParamT >, cgv::math::smooth_interpolator< ValueT, ParamT >, cgv::math::function_ref_interpolator< ValueT, ParamT >, and cgv::media::schemes::rgb_per_channel_piecewise_interpolator< ParamT >.

◆ quantize()

inlinevirtual |
Return a sequence of n uniformly-spaced samples from the interpolator within the parameter range [0,1].
The first sample is always located at t = 0 and the last sample is always located at t = 1. A derived class might override this function in order to provide a more efficient implementation.
- Parameters
-
n The number of samples to be evaluated.
- Returns
- The sequence of values.
Reimplemented in cgv::math::uniform_linear_interpolator< ValueT, ParamT >, and cgv::math::linear_interpolator< ValueT, ParamT >.
