Zoom Tool
This tool allows the user to zoom on a specific part of the scene.
The tool can be used by following these steps:
- Press the "zoom" command under the Navigation menu.
- Drag the mouse while pressing the left mouse button to draw a rectangle in the 3D view.
- Release the mouse: the camera zooms into the new defined viewport. The system then changes back to the last navigation mode used.
Difference with respect to the Move to viewport tool
With the zoom tool the camera is zoomed-in a detail of the scene. Only the field of view (in perspective mode), or the projection size (in orthographic mode) is changed.
With move to viewport, the camera is translated closer to the detail indicated by the rectangle, leaving the field of view unchanged.
