### 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.
|
|
|
|
