This is a simple fractal program I wrote.
- Hold down the left mouse button or scroll wheel to drag the image around.
- Use the scroll wheel to zoom in and out.
- You can also hold down the right mouse button to zoom in.
It's multithreaded, so if you have a dual- or quad-core processor you will see an almost linear increase in framerate.
My 2.4GHz Core 2 Quad gets 15.58 frames per second on the built-in benchmark (600x600).
The algorithm is straightforward escape time, with double precision math and 256 iterations. One twist is that I compute two pixels in the inner loop instead of one, which improves performance by about 40% because of superscalar execution. (No vector instructions yet.) |
