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.

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
sourcePos3D label coordinates
sourceCameramain view camera
sourceViewportmain viewport
