    1st commit

    2025-6-6

    added utility node

    • PerlinCoordinateRandomizerNode
      Applies Perlin noise-based randomization to coordinate data, adding natural, smooth variations to tracking points across frames.
    • XYMotionAmplifierNode
      Amplifies coordinate movement with directional control for X/Y axes, preserving static points while enhancing motion intensity with optional mask-based selection.
    • GridPointGeneratorNode
      Generates a grid of coordinate points.

    Added the enable_backward option. This is an experimental feature intended for tracking objects that don't appear in the first frame.
    Fixed a bug where the min_distance option was sometimes ignored.

    ver 1.0.3
