# MPSGraphDepthwiseConvolution3DOpDescriptor

The class that defines the parameters for a 3D-depthwise convolution operation.

```
class MPSGraphDepthwiseConvolution3DOpDescriptor
```

## Overview

A `MPSGraphDepthwiseConvolution3DOpDescriptor` defines constant parameters for 3D depthwise convolutions.
Use this class with [`depthwiseConvolution3D(_:weights:descriptor:name:)`](/documentation/MetalPerformanceShadersGraph/MPSGraph/depthwiseConvolution3D(_:weights:descriptor:name:)),
[`depthwiseConvolution3DDataGradient(_:weights:outputShape:descriptor:name:)`](/documentation/MetalPerformanceShadersGraph/MPSGraph/depthwiseConvolution3DDataGradient(_:weights:outputShape:descriptor:name:))
and [`depthwiseConvolution3DWeightsGradient(_:source:outputShape:descriptor:name:)`](/documentation/MetalPerformanceShadersGraph/MPSGraph/depthwiseConvolution3DWeightsGradient(_:source:outputShape:descriptor:name:))
methods.
