Time Taken to Decimate

Computers Used

We used three computers for testing. The first system (DUAL) has two Intel Celeron 450 MHz processors with 640 MB of RAM running Linux 2.4. The second system (BLACK) has an AMD K6-2 400 Mhz CPU with 378 MB RAM running Linux 2.4. The third system (DELL) has a Pentium III 750 MHz CPU with 378 MB of RAM running Windows 2000 Professional.

Time Test Results

Each test computer ran our program on each of the test models undisturbed once, and we recorded the output to a file. These graphs will give us solid evidence on which operating system and hardware configuration is optimal for our programs performance.

The first test is the time comparison of each computer at three levels of detail for the bunny model. Figure shows the results of this comparison.

Figure: The results of each computer for three levels of detail (60, 80, 90 percent) for model bunny.

The second test is the time comparison of each computer at three levels of detail for the test009 model. Figure shows the results of this comparison.

Figure: The results of each computer for three levels of detail (60, 80, 90 percent) for model test009.

The third test is the time comparison of each computer at three levels of detail for the hand model. Figure shows the results of this comparison.

Figure: The results of each computer for three levels of detail (60, 80, 90 percent) for model hand.

The next set of tests is a time comparison across the six largest test models, but for a single level of detail. The next figure (Figure ) shows the results of the time comparison at sixty percent of the vertices removed.

Figure: The time comparison for each computer across the six largest test models for the sixty percent level of detail.

The next figure (Figure ) shows the results of the time comparison at eighty percent of the vertices removed.

Figure: The time comparison for each computer across the six largest test models for the eighty percent level of detail.

The last figure (Figure ) shows the results of the time comparison at ninety percent of the vertices removed.

Figure: The time comparison for each computer across the six largest test models for the ninety percent level of detail.

In this graph we see extremely similar results to the previous two graphs. The previous two graphs show the decimation process completed in less time, but the order of computers finishing the decimation stay the same. This consistency leads us to believe that our testing methods were accurate, and our analysis can extrapolate precise conclusions.
