![]() TYPE A tests were done with Tile Cache and New All O2, Octane andįuel systems tested with 6.5.26m, while all Indy and Indigo2 systems Namely a Seagate Cheetah ST336704LCV U160 36GB 1" 10000rpm SCA (I'veĭone this recently for the Lynx compilation test). Redo the TYPE A tests to use the same model of disk in every system, System is shown after the tables below, though eventually I intend to Since some disk I/O is involved, the model of disk used for each System will perform for different imaging tasks.įor multi-CPU systems, only one CPU is used for these tests. Together, this combination of tests offers a broader picture of how a fp calculations - this isĮspecially true of the scripts which make use of multiple processing This is because it's hard to know exactly whatĮach test is doing in terms of int vs. Note that these tests are not described as specifically integer orįloating-point rather, they are referred to as image ![]() TYPE B: A render test which creates a new small 1K x 1K imageįrom scratch.Important to have plenty of RAM to run this type of test. Saved to disk (this could easily be 1/5th of the overall time). Process, followed by what could be a long wait while the data is TYPE A: An operation on a large image which take a long time to.GIMP is a good program to use for a more complex benchmark taskīecause it's easy to install, eays to use, and I can construct System, then consult the pages for the GIMP V1.0.4 tests. To compare GIMP performance on R4K systems, or between an R4K and a non-R4K tga don’t compress the file.IMAGING Test 4: GIMP V2.2.8 Tests (All) SGI Performance Comparisons Image Processing Tests With Neko GIMP V2.2.8 Last Change: 04/Aug/2010 NOTE: I have not yet run these tests on older R4K systems. You can also use the ripple filter on the layer mask.įor additional highlights, add a transparent layer on top and add your highlights, then run gaussian blur, the top layer opacity must be set to a very low value in this case. Experiment with Period and Amplitude until you like it. If you want curly hair, go to filters now and choose Filters, Distort, Ripple.

Re-open Filter, Noise and add HSV Noise, with a Holdness of 1, you can play with the other settings. Open Filters, Artistic and Cubism, run the cubism filter with a Tile size of 30, Saturation 2.5 Use the paintbrush tool with a big brush and paint black stripes on your white background. ![]() Open a new image in the size of your hair texture image. Set the background color back to white and the foreground color to black. Don’t reach for the eraser tool, let’s do that with a layer mask. Go to Colors, adjust Hue and Saturation, Contrast and Brightness. You can run Filters again after this step and add some Gaussian blur but don’t overdo it, a value of 0.7 or 0.8 is sufficient.
