Vec2ToScalarUnaryOperation

Documentation

  • Class name: CM_Vec2ToScalarUnaryOperation
  • Category: math/vec2
  • Output node: False

This node performs a unary operation that transforms a 2-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 a single numerical outcome.

Input types

Required

  • op
    • Specifies the unary operation to be performed on the vector, determining the nature of the transformation from a 2D vector to a scalar value.
    • Comfy dtype: COMBO[STRING]
    • Python dtype: List[str]
  • a
    • The 2-dimensional vector to be transformed into a scalar value through the specified operation.
    • Comfy dtype: VEC2
    • Python dtype: Vec2

Output types

  • float
    • Comfy dtype: FLOAT
    • The scalar result of the unary operation performed on the input 2-dimensional vector.
    • Python dtype: float

Usage tips

  • Infra type: GPU
  • Common nodes: unknown
