Documentation

• Class name: KfSinusoidalGetAmplitude
• Category: ROOT_CATEGORY
• Output node: False
• Repo Ref: https://github.com/dmarx/ComfyUI-Keyframed

该节点从弦曲线中提取振幅，提供了曲线偏离平均值的峰值偏差的度量。这对于理解曲线中振荡的强度至关重要。

Input types

Required

• curve
  • 输入的曲线参数代表从中提取振幅的正弦数据结构。它对节点的运行至关重要，因为它直接影响输出结果。
  • Comfy dtype: SINUSOIDAL_CURVE
  • Python dtype: keyframed.SinusoidalCurve

Output types

• amplitude
  • 输出提供输入正弦曲线的振幅，表明其振荡的范围。
  • Comfy dtype: FLOAT
  • Python dtype: float

Usage tips

• Infra type: CPU
