	project a 3D position from sourceCamera (in sourceViewport) to a 2D position for destCamera (in destViewport).

Detailed Description

3

Display 3D ortho axis in the main 3D view.

Axis are displayed in a dedicated viewport which can be placed all around the main viewport. Axis labels are displayed in a dedicated viewport with a specific camera to act as a billboarding layer. Axis labels can be changed with the mode combo box from the navigation widget.

Note: Not available in Python bindings

Since: QGIS 3.26

		QgsCameraController *	camera,
		Qgs3DMapSettings *	map
	)

Default Qgs3DAxis constructor.

Member Function Documentation

◆ from3DTo2DLabelPosition()

QVector3D Qgs3DAxis::from3DTo2DLabelPosition	(	const QVector3D &	sourcePos,
		Qt3DRender::QCamera *	sourceCamera,
		Qt3DRender::QViewport *	sourceViewport,
		Qt3DRender::QCamera *	destCamera,
		Qt3DRender::QViewport *	destViewport,
		const QSize &	destSize
	)

project a 3D position from sourceCamera (in sourceViewport) to a 2D position for destCamera (in destViewport).

destCamera and the destViewport act as a billboarding layer. The labels displayed by this process will always face the camera.

Parameters

sourcePos	3D label coordinates
sourceCamera	main view camera
sourceViewport	main viewport
destCamera	billboarding camera
destViewport	billboarding viewport
destSize	main qt3d window size

Returns
