Vec3ScalarOperation

Documentation

• Class name: CM_Vec3ScalarOperation
• Category: math/vec3
• Output node: False

Performs scalar operations on 3-dimensional vectors, allowing for mathematical manipulations such as scaling and division by a scalar value.

Input types

Required

• op
  • Specifies the scalar operation to be performed on the vector, such as multiplication or division, influencing the resulting vector's magnitude or direction.
  • Comfy dtype: COMBO[STRING]
  • Python dtype: str
• a
  • The 3-dimensional vector to be operated on, serving as the primary operand for the scalar operation.
  • Comfy dtype: VEC3
  • Python dtype: Vec3
• b
  • The scalar value to be used in the operation, affecting the vector's magnitude or direction based on the specified operation.
  • Comfy dtype: FLOAT
  • Python dtype: float

Output types

• vec3
  • Comfy dtype: VEC3
  • The resulting 3-dimensional vector after applying the specified scalar operation, reflecting changes in magnitude or direction.
  • Python dtype: tuple[Vec3]

Usage tips

• Infra type: CPU
• Common nodes: unknown
