Vec4UnaryOperation

Documentation

• Class name: CM_Vec4UnaryOperation
• Category: math/vec4
• Output node: False

This node performs unary operations on 4-dimensional vectors, applying a specified operation to a single Vec4 input and producing a Vec4 output. It abstracts complex vector manipulations into simple, callable operations, facilitating mathematical computations on 4D vectors.

Input types

Required

• op
  • Specifies the unary operation to be performed on the Vec4 input. The choice of operation directly influences the result, enabling a variety of mathematical manipulations.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: List[str]
• a
  • The Vec4 input on which the unary operation is to be performed. This vector serves as the primary data for the operation, determining the nature of the computation.
  • Comfy dtype: VEC4
  • Python dtype: Vec4

Output types

• vec4
  • Comfy dtype: VEC4
  • The result of applying the specified unary operation on the Vec4 input, returned as a Vec4. This output encapsulates the transformed vector, reflecting the mathematical computation performed.
  • Python dtype: Tuple[Vec4]

Usage tips

• Infra type: CPU
• Common nodes: unknown
