The HOpCameraZoomBox class zooms the camera to a selected area.
HOpCameraZoomBox utilizes the drawing functionality of HOpConstructRectangle to define a selection rectangle, and then extends HOpConstructRectangle::OnLButtonUp to calculate a zoom factor and direction.
The operation consists of the following steps:
-
Left Button Down: Registers the first point of the selection rectangle.
-
Left Button Down and Drag: Rubberbands the rectangle to desired dimensions.
-
Left Button Up: The is viewpoint calculated, camera position changed and the operation ends.
