QRasterMode Class

(Qt3DRender::QRasterMode)

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

Header: #include <QRasterMode>

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.

enum QRasterMode::FaceMode

Enumeration for face mode values

Constant Value Description
Qt3DRender::QRasterMode::Front 0x0404 Applies to front faces only

enum QRasterMode::RasterMode

Enumeration for raster mode values

Constant Value Description
Qt3DRender::QRasterMode::Points 0x1B00 Vertices at the start of an edge are drawn as points.
Qt3DRender::QRasterMode::Lines 0x1B01 Edges of a polygon are draw as line segments.
Qt3DRender::QRasterMode::Fill 0x1B02 Fills the interior of the primitive.
