## Detailed Description

A Qt3DRender::QStencilTest class specifies argument for the stencil test. The stencil test comprises of three arguments: stencil test function, stencil test mask and stencil reference value. QStencilTest allows these arguments to be set for both front- and back-facing polygons separately.
