# DracoCompressionOptions class

Namespace: [Rhino.FileIO](https://developer.rhino3d.com/api/rhinocommon/namespace/rhino.fileio.md) · Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md)

```cs
public class DracoCompressionOptions
```

Options for applying Draco compression

## Constructors

- [DracoCompressionOptions](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/ctor.md): Initializes to default options

## Fields

- [IncludeNormals](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/includenormals.md): Include vertex normals in the compressed data.
- [IncludeTextureCoordinates](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/includetexturecoordinates.md): Include texture coordinates in the compressed data.
- [IncludeVertexColors](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/includevertexcolors.md): Include vertex colors in the compressed data.
- [VertexColorFormat](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/vertexcolorformat.md): Color format of vertex colors in compressed data

## Properties

- [CompressionLevel](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/compressionlevel.md): Compression level. 0 if fastest, but least compression. 10 is slowest, but best compression
- [NormalQuantizationBits](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/normalquantizationbits.md): Sets the quantization compression options for normal values. The values will be quantized in a box defined by the maximum extent of the values. I.e., the actual precision of this option depends on the scale of the attribute values.
- [PositionQuantizationBits](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/positionquantizationbits.md): Sets the quantization compression options for position values. The values will be quantized in a box defined by the maximum extent of the values. I.e., the actual precision of this option depends on the scale of the attribute values.
- [TextureCoordintateQuantizationBits](https://developer.rhino3d.com/api/rhinocommon/type/rhino.fileio.dracocompressionoptions/texturecoordintatequantizationbits.md): Sets the quantization compression options for texture coordinate values. The values will be quantized in a box defined by the maximum extent of the values. I.e., the actual precision of this option depends on the scale of the attribute values.
