Detailed Description

Forward rendering is what OpenGL traditionally uses. It renders directly to the backbuffer one object at a time shading each one as it goes.

QForwardRenderer is a single leaf FrameGraph tree which contains a QViewport , a QCameraSelector , and a QClearBuffers . The QForwardRenderer has a default requirement filter key whose name is “renderingStyle” and value “forward”. If you need to filter out your techniques, you should do so based on that filter key.

By default the viewport occupies the whole screen and the clear color is white. Frustum culling is also enabled.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property buffersToClearᅟ: Qt3DRender.QClearBuffers.BufferType

Holds the current buffers to be cleared. Default value is ColorDepthBuffer

Access functions:
property cameraᅟ: QEntity

Holds the current camera entity used to render the scene.

Note

A camera is a QEntity that has a QCameraLens as one of its components.

Access functions:
property clearColorᅟ: QColor

Holds the current clear color of the scene. The frame buffer is initialized to the clear color before rendering.

Access functions:
property externalRenderTargetSizeᅟ: QSize

Contains the size of the external render target. External render targets are relevant when rendering does not target a window surface (as set in surface ).

Access functions:
property frustumCullingᅟ: bool

Indicates if the renderer applies frustum culling to the scene.

Access functions:
property gammaᅟ: float

Holds the gamma value the renderer applies to the scene.

Access functions:
property showDebugOverlayᅟ: bool

If true, a debug overlay will be rendered over the scene. It will show detailed information about the runtime rendering state, let the user turn logging on and off, etc.

Access functions:
property surfaceᅟ: QObject

Holds the current render surface.

Access functions:
property viewportRectᅟ: QRectF

Holds the current normalized viewport rectangle.

Access functions:
property windowᅟ: QObject

Holds the current render surface.

Access functions:
__init__([parent=None])
Parameters:

parentQNode
