Vec3ToScalarBinaryOperation

Documentation

• Class name: CM_Vec3ToScalarBinaryOperation
• Category: math/vec3
• Output node: False

This node performs a binary operation between two 3-dimensional vectors (Vec3) and returns a scalar value as a result. It supports a variety of operations such as dot product and distance calculation, abstracting complex mathematical operations into a simple interface.

Input types

Required

• op
  • Specifies the binary operation to be performed on the two Vec3 inputs, such as dot product or distance calculation. This choice determines how the vectors are mathematically combined.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• a
  • The first 3-dimensional vector (Vec3) input for the binary operation.
  • Comfy dtype: VEC3
  • Python dtype: Vec3
• b
  • The second 3-dimensional vector (Vec3) input for the binary operation.
  • Comfy dtype: VEC3
  • Python dtype: Vec3

Output types

• float
  • Comfy dtype: FLOAT
  • The scalar result of the binary operation performed on the two Vec3 inputs.
  • Python dtype: float

Usage tips

• Infra type: CPU
• Common nodes: unknown
