Rotate  local vectors in a vector field around local vectors in an "axis" vector field. Define the amount of rotate with an scalar field in degrees.

## Installation

Clone this repo or copy the package folder into your nTop workspace:

```bash theme={null}
git clone https://github.com/nTopology/Utilities-community.git
```

The package lives at `packages/DaveMakesStuff/rotate-vector-field-with-axis-field/`.

## Usage

1. Open the provided `.ntop` file in nTop 4.12+.
2. Input appropriate vector and scalar fields
