VAPOR GUI allows the user to click and drag the mouse in the 3D scene in order to provide an intuitive way to control how the data is being visualized. By default, in Navigation mode, the mouse controls the camera view as follows:
When there are multiple visualization windows, clicking in one window makes it the current window, so that all the values in the parameter tabs then are associated with that window.
Dragging the mouse with the Left mouse button pressed results in a rotation of the scene, about the rotation center.
Dragging the mouse up and down with the right mouse button pressed results in a zoom in our out of the scene, toward or away from the rotation center.
Dragging the mouse with the middle mouse button pressed results in a translation of the camera and of the rotation center.
In Navigation mode, the mouse controls only the above changes in viewpoint and focus.
There are, in addition, mouse modes for each of the different boxes that can appear in the scene:
Region mode
Flow rake mode
Probe mode
Barb rake mode
2D mode
Image mode
Colorbar mode
Contours mode
A mouse mode is selected using the mouse mode selector near the upper left-hand corner of the main VAPOR GUI window.
In each of the above modes, the mouse can be used to translate or stretch the associated box in the scene. The boxes have cubic handles aligned with the X, Y, and Z axes. By clicking and dragging a handle with the left mouse button pressed, the box is translated in the direction of the mouse drag. By clicking and dragging with the right mouse button pressed, the box is stretched along the axis of the mouse drag. If the mouse is dragged without selecting one of the box handles, the viewpoint is manipulated as in Navigation mode as described above.
When using a rotated 3D box for a Probe or Contour renderer, the box stretching (with the right mouse button) is disabled whenever the box is not axis-aligned.
