This is an STL reader and writer written in Go.

These core methods are to handle reading from an io.Reader and writing to an io.Writer. Because most applications use files, these are wrapped in helper functions explained below.

This takes in a filename and will return an stl.Solid. This read method will automatically determine if the file is binary or ASCII and handle it appropriately.

This reader is concurrent. For binary files, it gives about a 60% speedup on an E3-1231 v3 @ 3.40GHz reading off a SATA SSD.

This will write an stl.Solid to a file in ASCII format. The representations of the numbers are minimized to save some space.

This will write an stl.Solid to a file in binary format. This format is much more space efficient.

solid, err := stl.FromFile("/path/to/file.stl")
if err != nil {
    t.Errorf("could not read stl: %v", err)
}

err = solid.ToASCIIFile("/path/to/file.stl")
if err != nil {
    t.Errorf("could not write to file: %v", err)
}
