QRasterMode Class

class Qt3DRender::QRasterMode

The QRasterMode render state allows to control the type of rasterization to be performed. More...

Header: #include <QRasterMode>
qmake: QT += 3drender
Since: Qt 5.14
Instantiated By: RasterMode
Inherits: Qt3DRender::QRenderState

This class was introduced in Qt 5.14.

Public Types

enum FaceMode { Front, Back, FrontAndBack }
enum RasterMode { Points, Lines, Fill }

Properties

Public Functions

Qt3DRender::QRasterMode::FaceMode faceMode() const
Qt3DRender::QRasterMode::RasterMode rasterMode() const

Public Slots

void setFaceMode(Qt3DRender::QRasterMode::FaceMode faceMode)
void setRasterMode(Qt3DRender::QRasterMode::RasterMode rasterMode)

Signals

void faceModeChanged(Qt3DRender::QRasterMode::FaceMode faceMode)
void rasterModeChanged(Qt3DRender::QRasterMode::RasterMode rasterMode)

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.
