### Install

    go get -u github.com/fogleman/simplify/cmd/simplify

### Command-Line Usage

    Usage: simplify [-f FACTOR] input.stl output.stl

    $ simplify -f 0.1 bunny.stl out.stl

    Loading bunny.stl

    Input mesh contains 270021 faces

    Simplifying to 10% of original...

    Output mesh contains 27001 faces

    Writing out.stl

### API Usage

```go

// Use LoadSTL (ASCII) or LoadBinarySTL

mesh, err := simplify.LoadBinarySTL(inputPath)

// handle err

mesh = mesh.Simplify(factor)

mesh.SaveBinarySTL(outputPath)

```
