ComfyUI Node: Vec4UnaryCondition

Vec4UnaryCondition:

The CM_Vec4UnaryCondition node is designed to evaluate a specific condition on a 4-dimensional vector (Vec4) and return a boolean result. This node is particularly useful in mathematical and logical operations where you need to check certain properties or conditions of a Vec4, such as whether all components are positive, if the vector is normalized, or other unary conditions. By leveraging this node, you can streamline complex vector evaluations into a single, easy-to-use operation, making it an essential tool for AI artists working with vector data in their creative projects.

Vec4UnaryCondition Input Parameters:

op

The op parameter specifies the unary condition to be applied to the Vec4. It is a selection from a predefined list of conditions, each representing a different unary operation. The available options are derived from the VEC_UNARY_CONDITIONS dictionary. This parameter determines the specific condition that will be evaluated on the input vector. There are no minimum or maximum values as it is a categorical selection.

a

The a parameter represents the input Vec4 on which the unary condition will be evaluated. This is a 4-dimensional vector with default values provided by DEFAULT_VEC4. The vector components can be any floating-point numbers, and the condition specified by op will be applied to this vector to produce the boolean result.

Vec4UnaryCondition Output Parameters:

BOOL

The output of the CM_Vec4UnaryCondition node is a boolean value (BOOL). This output indicates whether the specified unary condition (op) holds true for the input Vec4 (a). If the condition is met, the output will be True; otherwise, it will be False. This boolean result can be used in further logical operations or as a control mechanism in your AI art workflows.

Vec4UnaryCondition Usage Tips:

• Ensure that you select the correct unary condition (op) that matches your intended evaluation for the Vec4. Different conditions can yield significantly different results.
• Use this node to filter or control the flow of your AI art project based on specific vector properties, such as checking if a vector is normalized before using it in a shader or transformation.

Vec4UnaryCondition Common Errors and Solutions:

Invalid operation selected

• Explanation: The op parameter value does not match any of the keys in the VEC_UNARY_CONDITIONS dictionary.
• Solution: Verify that the op parameter is set to one of the valid options provided by the VEC_UNARY_CONDITIONS dictionary.

Input vector is not a Vec4

• Explanation: The a parameter is not a valid 4-dimensional vector.
• Solution: Ensure that the input vector a is correctly formatted as a Vec4, with four numerical components.

Condition function error

• Explanation: An error occurred while applying the condition function to the input vector.
• Solution: Check the implementation of the condition function in the VEC_UNARY_CONDITIONS dictionary to ensure it handles all possible Vec4 inputs correctly.
