Vec4ScalarOperation

Documentation

• Class name: CM_Vec4ScalarOperation
• Category: math/vec4
• Output node: False

Performs scalar operations on 4-dimensional vectors, allowing for the manipulation of vector components with a scalar value. This node abstracts mathematical operations such as multiplication or division, facilitating vector transformations in a 4D space.

Input types

Required

• op
  • Specifies the scalar operation to be performed on the vector, such as multiplication or division, influencing the resulting vector transformation.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• a
  • The 4-dimensional vector to be transformed, serving as the primary operand in the scalar operation.
  • Comfy dtype: VEC4
  • Python dtype: Vec4
• b
  • The scalar value to be applied to the vector, acting as the secondary operand in the operation.
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• vec4
  • Comfy dtype: VEC4
  • The transformed 4-dimensional vector resulting from the specified scalar operation.
  • Python dtype: tuple[Vec4]

Usage tips

• Infra type: CPU
• Common nodes: unknown
