This document describes how to access functionality that used to be reserved for the TwoHanded interface with the mouse. This document is broken down into three major sections, one describing mouse based transforms , one describing subsetting with the mouse and one describing the volume cutting with the mouse . With trackers, SFA lets you grab the scene with the non-dominant hand cursor and reposition and orient the scene. There is a similar set of functionality available with the mouse. That is, unlike the other mouse based functionality, you don't need to press a key on the keyboard to perform mouse based transforms.
Rotation is performed by pressing the left mouse button and moving the mouse.
As the user drags the mouse, it acts as a virtual trackball , allowing the user to rotate around all three axes simultaneously. Experimentation with this technique is the best way to learn how to use it. Scaling can be thought of as translation along the Z axes. By pressing and holding the right mouse button and dragging the mouse, the scene with either appear to get closer to the user or farther away, depending on the mouse movement. This allows the user to bring the scene closer to inspect an area more closely, or to move the scene away to get a broader idea of the entire dataset.
