IndexedGradientSampler< T_ModeNone, T_ModeLinearKnot, T_ModeSmoothKnot, T_ModeBlend, T_ModeCubicKnot, T_ModeCubicBias > Class Template Reference

#include <gradientmath.h>

详细描述

template<UInt T_ModeNone = 0, UInt T_ModeLinearKnot = 1, UInt T_ModeSmoothKnot = 2, UInt T_ModeBlend = 3, UInt T_ModeCubicKnot = 4, UInt T_ModeCubicBias = 5>
class maxon::IndexedGradientSampler< T_ModeNone, T_ModeLinearKnot, T_ModeSmoothKnot, T_ModeBlend, T_ModeCubicKnot, T_ModeCubicBias >

This class implements the gradient blending operation for a series of knots with different interpolation modes. For performance reasons interpolation modes are handled as unsigned integers.

Template Parameters
T_ModeNone The index of constant / stairstep interpolation of 1 knot.
T_ModeLinearKnot The index of linear interpolation between 2 knots.
T_ModeSmoothKnot The index of the smooth-stepped linear interpolation between 2 knots.
T_ModeBlend The index of the box-stepped linear interpolation between 2 knots.
T_ModeCubicKnot The index of the cubic interpolation between 4 knots.
T_ModeCubicBias The index of the cubic interpolation between 2 knots.
