Perform mathematical operations between 2D vector and scalar, aiding AI artists in vector manipulation for scaling and normalization.

The `CM_Vec2ScalarOperation`

node is designed to perform mathematical operations between a 2-dimensional vector (Vec2) and a scalar (float). This node is particularly useful for AI artists who need to manipulate vector data in their projects, such as scaling or normalizing vectors. By providing a simple interface to apply operations like multiplication and division, this node helps streamline complex mathematical tasks, making it easier to achieve desired transformations and effects in your creative workflows.

This parameter specifies the operation to be performed between the vector 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 its magnitude, while dividing it will reduce its magnitude. There are no minimum or maximum values for this parameter, but it must be one of the predefined operations.

This parameter represents the 2-dimensional vector (Vec2) that will be used in the operation. The vector is defined as a tuple of two floating-point numbers. The default value is `(0.0, 0.0)`

, which represents a zero vector. The vector `a`

is the primary data that will be manipulated by the chosen operation.

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

. The scalar can be any floating-point number and will directly influence the result of the operation. For instance, if the operation is `Mul`

, the vector will be scaled by this scalar. There are no predefined minimum or maximum values for this parameter, but it should be chosen carefully to achieve the desired effect.

The output parameter is a 2-dimensional vector (Vec2) 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 processes within your project. Understanding the output vector is essential for ensuring that the transformations align with your creative goals.

- When scaling a vector, use the
`Mul`

operation with a scalar greater than 1 to increase its magnitude or a scalar between 0 and 1 to decrease it. - Use the
`Div`

operation to normalize a vector by dividing it by its magnitude, effectively reducing its length to 1 while maintaining its direction.

**Explanation**: This error occurs when the`Div`

operation is selected and the scalar`b`

is set to zero.**Solution**: Ensure that the scalar`b`

is a non-zero value when performing division operations to avoid this error.

**Explanation**: This error occurs if an operation other than`Mul`

or`Div`

is specified.**Solution**: Verify that the`op`

parameter is set to either`Mul`

or`Div`

to ensure valid operations are performed.

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

is not a valid 2-dimensional vector.**Solution**: Ensure that the input vector`a`

is a tuple of two floating-point numbers to avoid this error.
