Cosines

Documentation

• Class name: DF_Cosines
• Category: Derfuu_Nodes/Math/Trigonometry
• Output node: False

The Cosines node calculates the cosine of a given angle, with the option to compute the arc cosine instead. It supports angles in both degrees and radians, allowing for flexible trigonometric calculations.

Input types

Required

• value
  • The numerical value of the angle for which the cosine (or arc cosine) is to be calculated. This value determines the specific angle involved in the trigonometric operation.
  • Comfy dtype: FLOAT
  • Python dtype: float
• type_
  • Specifies the unit of the input angle: radians ('RAD') or degrees ('DEG'). This affects how the angle is interpreted for the trigonometric calculation.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• arcCos
  • A boolean flag that, when set to True, changes the operation from calculating the cosine to calculating the arc cosine of the given angle.
  • Comfy dtype: COMBO[BOOLEAN]
  • Python dtype: bool

Output types

• float
  • Comfy dtype: FLOAT
  • The result of the cosine (or arc cosine) calculation for the given angle.
  • Python dtype: float

Usage tips

• Infra type: CPU
• Common nodes: unknown
