Bring up the Navigator window by checking the menu item ‘Navigator’ in the ‘Windows’ menu.
The Orientation control is a frame of three orthogonal vectors: Up (red), Right (green) and Heading (blue). The frame uses the standard navigational terms of Yaw, Pitch and Roll. To reset the camera to its default orientation, click the small white sphere at the frame origin.
Right-Click on the Up vector and it highlights yellow. Drag the mouse left or right.
Right-click on the Right vector and it highlights yellow. Drag the mouse left or right.
Right-click on the Heading vector and it highlights yellow. Drag the mouse left or right.
The tracking control has four orthogonal vectors for Up, Down, Left and Right. These operate in the same way as the orientation control. If the ‘World’ toggle button is down, the camera moves along the corresponding world vector, rather than the camera vector. To reset camera tracking, click the white sphere at the centre of the control.
The dolly control moves the camera along its Heading vector, in or out of the scene. If the ‘World’ toggle button is down, the canera moves along the the world heading vector. Right-click on the heading vector and it highlights yellow. Drag the mouse along the diagonal, up or down.
The dolly control is disabled when you create or select a non-perspective camera and click in the view. However, you can “zoom” a non perspective camera by changing the field of view in the frustum window. Choose the the menu View->Set Frustums... then drag on the fov slider.
Note: when you click a camera control, the direction to drag is indicated by small black arrows. The further you drag the mouse from the control, the faster the transformation.
