Vec4ToScalarBinaryOperation

Documentation

  • Class name: CM_Vec4ToScalarBinaryOperation
  • Category: math/vec4
  • Output node: False

This node performs a binary operation between two Vec4 vectors, resulting in a scalar value. It supports operations like dot product and distance calculation, transforming vector relationships into a single numerical outcome.

Input types

Required

  • op
    • Specifies the binary operation to be performed, such as dot product or distance, affecting the scalar result.
    • Comfy dtype: COMBO[STRING]
    • Python dtype: str
  • a
    • The first Vec4 vector operand in the binary operation.
    • Comfy dtype: VEC4
    • Python dtype: Vec4
  • b
    • The second Vec4 vector operand in the binary operation.
    • Comfy dtype: VEC4
    • Python dtype: Vec4

Output types

  • float
    • Comfy dtype: FLOAT
    • The scalar result of the binary operation between the two Vec4 vectors.
    • Python dtype: float

Usage tips

  • Infra type: GPU
  • Common nodes: unknown
