ComfyUI Node: Lerp 📅🅕🅝

Lerp 📅🅕🅝:

The Lerp node is designed to perform linear interpolation, a fundamental operation in various fields such as computer graphics, animation, and data visualization. This node calculates an interpolated value between a starting and ending point based on a given strength and the current frame. The primary benefit of using the Lerp node is its ability to smoothly transition between values, which is particularly useful for creating animations or gradual changes in visual effects. By adjusting the strength and the number of images, you can control the rate and smoothness of the transition, making it a versatile tool for AI artists looking to add dynamic elements to their projects.

Lerp 📅🅕🅝 Input Parameters:

num_Images

This parameter specifies the total number of images or frames over which the interpolation will occur. It determines the range of the interpolation and affects how gradual or abrupt the transition will be. The minimum value is 0.0, the maximum value is 9999.0, and the default value is 1.0. Adjusting this parameter allows you to control the overall duration of the interpolation.

strength

The strength parameter defines the initial value from which the interpolation starts. It influences the magnitude of the transition and how much change occurs between frames. The minimum value is 0.0, the maximum value is 10.0, and the default value is 1.0. By modifying the strength, you can control the intensity of the interpolation effect.

current_frame

This parameter indicates the current frame or step in the interpolation process. It is used to calculate the interpolated value at a specific point in time. The minimum value is 0.0, the maximum value is 9999, and the default value is 1.0. Changing the current_frame allows you to retrieve the interpolated value at different stages of the transition.

Lerp 📅🅕🅝 Output Parameters:

FLOAT

The FLOAT output represents the interpolated value as a floating-point number. This value is calculated based on the strength, number of images, and the current frame. It provides a precise measure of the interpolation at a given point, which can be used for various applications such as adjusting visual effects or animating properties.

INT

The INT output is the integer representation of the interpolated value. This value is derived by converting the FLOAT output to an integer, which can be useful for scenarios where discrete values are required, such as frame indices or step counts in animations.

Lerp 📅🅕🅝 Usage Tips:

• To create smooth transitions in animations, set the num_Images parameter to a higher value, which will spread the interpolation over more frames and result in a gradual change.
• Adjust the strength parameter to control the intensity of the interpolation. A higher strength will result in a more pronounced transition, while a lower strength will create a subtler effect.
• Use the current_frame parameter to retrieve the interpolated value at different stages of the transition. This can be useful for synchronizing the interpolation with other elements in your project.
