Perform mathematical operations between 3D vector and scalar for AI artists, simplifying complex transformations.

The `CM_Vec3ScalarOperation`

node is designed to perform mathematical operations between a 3-dimensional vector (Vec3) and a scalar (float). This node is particularly useful for AI artists who need to manipulate 3D vectors in their projects, such as scaling or normalizing vectors. By providing a simple interface to apply operations like multiplication or division, this node helps streamline complex mathematical transformations, making it easier to achieve desired visual effects or calculations without requiring deep technical knowledge.

This parameter specifies the operation to be performed between the Vec3 and the scalar. The available options are "Mul" for multiplication and "Div" for division. Choosing the correct operation is crucial as it determines how the vector will be transformed. For example, multiplying a vector by a scalar will scale the vector, while dividing it will reduce its magnitude.

This parameter represents the 3-dimensional vector (Vec3) that will be used in the operation. The vector is defined by three float values corresponding to its x, y, and z components. The vector `a`

is the primary input that will be manipulated by the chosen operation and scalar value.

This parameter is the scalar (float) value that will be used in the operation with the vector `a`

. The scalar can be any float value and will either multiply or divide the vector components based on the selected operation. The scalar value `b`

directly influences the magnitude of the resulting vector.

The output parameter is a 3-dimensional vector (Vec3) that results from the specified operation between the input vector `a`

and the scalar `b`

. This output vector reflects the transformation applied, such as scaling or normalizing, and can be used in subsequent nodes or visualizations.

- To scale a vector uniformly, use the "Mul" operation with a scalar greater than 1 to increase its size or a scalar between 0 and 1 to decrease its size.
- Use the "Div" operation to normalize a vector or reduce its magnitude, which can be useful for creating unit vectors or adjusting vector lengths.

**Explanation**: This error occurs when the scalar`b`

is set to zero while using the "Div" operation, leading to an undefined result.**Solution**: Ensure that the scalar`b`

is a non-zero value when performing division operations.

**Explanation**: This error happens if an unsupported operation is specified in the`op`

parameter.**Solution**: Verify that the`op`

parameter is set to either "Mul" or "Div" as these are the supported operations for this node.

**Explanation**: This error occurs if the input vector`a`

is not in the correct Vec3 format.**Solution**: Ensure that the input vector`a`

is a tuple or list containing exactly three float values representing the x, y, and z components.
