Visualizing Array Data Figure 136: Four Surface Views The Auto Reduce option lets you choose between viewing all your data points—which takes longer to appear in the display—or viewing the averaging of data over a number of nearby points. Figure 136 shows four different views of the same data, differing only in the selection of Surface and XY options. You can reset the viewing parameters to those used when you first invoked the Visualizer by selecting the View > Initialize View command, which restores all translation, rotation, and scaling to their initial state, and enlarges the display area slightly. 190 Chapter 9: Visualizing Programs and Data
Visualizing Array Data Manipulating Surface Data The actions that the Visualizer performs differ when you are in actor mode instead of camera mode, which is the default. In camera mode, the Visualizer pretends to be moving a “camera” that is showing you the view. In actor mode, the Visualizer assumes that changes to the way you are seeing the object are due to you changing your position. The difference between these is subtle. In some circumstances, actions such as pan and zoom in camera mode can also add a slight rotation to the object. From within TotalView, you can only see one array at a time. However, if you combine multiple datasets and visualize them externally, the differences between camera and actor mode can help differentiate the objects. The following table defines general commands that you can use while display a surface view. Command letters can be typed in either upper- or lower-case. Action Press Pick (show value): The Visualizer shows the value of the data point p underneath the cursor. Camera mode: Mouse events affect the camera position and focal c point. (Axes moves, and you don’t.) Actor mode: Mouse events affect the actor that is under the mouse a pointer. (You move, not the axes.) Joystick mode: Motion occurs continuously while you are pressing a j mouse button. Trackball mode: Motions only occurs when you press the mouse t button and you move the mouse pointer. Wireframe view: The Visualizer displays the surface as a mesh. (This is w the same as not checking the Surface option.) Surface view: The Visualizer displays the surface as a solid. (This is the s same as having checked the Surface option.) Reset: Removes some of the changes you’ve made to the way the r Visualizer displays an object. Initialize: Restores the object to what it was before you interacted with i the Visualizer. As this is a menubar accelerator, the window must have focus. Exit or Quit: Close the Visualizer or Ctrl-Q The following table defines the actions you can perform using your mouse: Action Click or Press Camera mode Actor mode Rotate camera around focal point (surface only) Zoom: you appear to get closer to the object. Pan: you move the “camera”. For example, moving the camera up means the object moves down. Rotate actor around focal point (surface only) Scale: the object appears to get larger Translate: The object moves in the direction you pull it.
