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
