This is a new navigation mode for QgsCameraController which is meant to work just like the terrain-based navigation mode, but for 3D scenes with globe. Initially, the new navigation mode can handle: - zooming in/out with mouse wheel - orbit around globe when dragging with left mouse button pressed - left/right/up/down keys to orbit around globe - shift + left/right keys to change heading angle - shift + up/down keys to change pitch angle - page up/page down keys to increase/decrease elevation For camera pose, we use QgsCameraPose as for "flat" scenes, but the QCamera is positioned/rotated slightly differently - the main change is that in case of globe, we use ECEF coordinates of the camera pose's center point, convert them to lat/lon coordinates in order to set up initial rotation of the camera so that it is perpendicular to the tangent plane at the given ECEF coordinate.

class QgsCameraPose
|

{

%Docstring(signature="appended")
|
|
Class that encapsulates camera pose in a 3D scene.
|
|
|
|
The pose is defined with the following parameters:
|
|
|
|
- center point - towards which point the camera is looking
|
|
- distance from the center point - how far is the camera from the point towards which it is looking
|
|
- pitch angle - vertical rotation of the camera (0 degrees = camera looking down, 90 degrees = camera looking from the side)
|
|
- yaw angle - horizontal rotation of the camera
|
|
|
|
