ComfyUI Node: 📈 Saw Curve

Saw Curve [Dream]:

The Saw Curve [Dream] node is designed to generate a sawtooth wave pattern, which is a type of non-sinusoidal waveform characterized by a linear rise and a sudden drop. This node is particularly useful in animation and procedural generation, where you need a repeating linear ramp effect. The sawtooth wave can be used to create smooth, periodic transitions in animations, giving a consistent and predictable pattern over time. By adjusting parameters such as the maximum and minimum values, periodicity, and phase, you can customize the waveform to fit your specific needs, making it a versatile tool for creating dynamic visual effects.

Saw Curve [Dream] Input Parameters:

max_value

This parameter sets the maximum value of the sawtooth wave. It determines the peak of the waveform, which is the highest point the wave will reach before resetting. The default value is 1.0, and it can be adjusted to any floating-point number to scale the amplitude of the wave.

min_value

This parameter sets the minimum value of the sawtooth wave. It determines the lowest point of the waveform before it starts rising again. The default value is 0.0, and it can be adjusted to any floating-point number to set the baseline of the wave.

periodicity_seconds

This parameter defines the duration of one complete cycle of the sawtooth wave in seconds. It controls how long it takes for the wave to rise from the minimum value to the maximum value and then drop back to the minimum value. The default value is 10.0 seconds, with a minimum allowable value of 0.01 seconds, allowing for both slow and fast oscillations.

phase

This parameter adjusts the phase of the sawtooth wave, effectively shifting the waveform left or right along the time axis. The phase value ranges from -1 to 1, with a default of 0.0. A positive phase value shifts the wave to the right, while a negative value shifts it to the left, allowing for synchronization with other waveforms or events.

Saw Curve [Dream] Output Parameters:

FLOAT

This output provides the current value of the sawtooth wave as a floating-point number. It represents the precise value of the waveform at the current time, which can be used for smooth transitions and continuous control in animations.

INT

This output provides the current value of the sawtooth wave as an integer. It is a rounded version of the FLOAT output, useful for scenarios where discrete values are needed, such as frame counts or step-based animations.

Saw Curve [Dream] Usage Tips:

• To create a smooth, repeating animation, set the periodicity_seconds to match the desired duration of one complete cycle.
• Use the phase parameter to synchronize the sawtooth wave with other animation curves or events, ensuring seamless transitions.
• Adjust the max_value and min_value to control the amplitude of the wave, tailoring the effect to your specific visual requirements.

Saw Curve [Dream] Common Errors and Solutions:

"Invalid periodicity_seconds value"

• Explanation: The periodicity_seconds parameter is set to a value less than the minimum allowed (0.01 seconds).
• Solution: Ensure that the periodicity_seconds value is set to 0.01 or higher.

"Phase value out of range"

• Explanation: The phase parameter is set to a value outside the allowed range of -1 to 1. - Solution: Adjust the phase parameter to be within the range of -1 to 1.

"Unexpected output type"

• Explanation: The node is expected to return both FLOAT and INT types, but an unexpected type is encountered.
• Solution: Verify the node's configuration and ensure it is correctly set up to return both FLOAT and INT outputs.
