Vec3ToScalarUnaryOperation

Documentation

  • Class name: CM_Vec3ToScalarUnaryOperation
  • Category: math/vec3
  • Output node: False

This node performs a unary operation that transforms a 3-dimensional vector into a scalar value, based on a specified operation. It abstracts complex mathematical operations into a simple interface, allowing for the transformation of vector data into scalar form.

Input types

Required

  • op
    • Specifies the unary operation to be performed on the 3-dimensional vector. This operation determines how the vector is transformed into a scalar value.
    • Comfy dtype: COMBO[STRING]
    • Python dtype: str
  • a
    • The 3-dimensional vector to be transformed into a scalar value through the specified unary operation.
    • Comfy dtype: VEC3
    • Python dtype: Vec3

Output types

  • float
    • Comfy dtype: FLOAT
    • The scalar result of applying the specified unary operation on the input 3-dimensional vector.
    • Python dtype: float

Usage tips

  • Infra type: CPU
  • Common nodes: unknown
