Qt3DRender::QRasterMode::RasterMode | rasterMode() const

## Public Slots

void | setFaceMode(Qt3DRender::QRasterMode::FaceMode faceMode)

## Signals

## Detailed Description

The QRasterMode class is used to control the rasterization step of the primitives at render time. This can be used to choose whether we only want to show points, edges or fill a primitive.

Note: This is not supported when rendering on OpenGL ES 2.0 platforms.

See also QAlphaTest and QStencilTest.
