Lightspeed on Your Desktop
You can change the dimensions of the default cube object by selecting the menu option File→New lattice (Figure 2). You can set how many balls will be drawn in each of the three dimensions. You also can change the smoothness factor when the object is rendered on the display. In this case, it will look like what is shown in Figure 3.

You also have the option of loading your own 3-D object, either in 3D Studio format (*.3DS or *.PRJ) or in LightWave format (*.LWO). This new object is what will be rendered, and the optical effects will be applied to this. You can save a snapshot of a particular object at a particular speed in either PNG or TIFF format. You also can export to an SRS file format (Special Relativity Scene). This is a format used by the program BACKLIGHT, which is a specialized raytracer used to illustrate relativistic effects. This lets you generate much higher resolution images of the affected object.
In the Objects menu item, there are options for drawing supplementary objects. By default, the floating grid is selected. You also can select coordinate axes, identifying the x, y and z axes. You can select the display of a bounding box for your object as well (Figure 4).

Additionally, you can animate the scene by selecting Objects→Animation in the menu. This pops up a dialog box where you can select the starting and ending points on the x axis and the loop time in seconds (Figure 5). The scene then will be animated until you click stop.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
