Quaternion Julia Navigator.

QJN is an easy to use yet advanced fractal imaging tool. It produces photorealistic texturemapped 3D slices of Quaternion Julia sets. Although this may sound difficult, QJN makes it easy for you. Here are some examples of images created by QJN. Please let us know what you think of QJN by sending us e-mail.


Here is a list of features QJN offers at this moment.
  1. finding Seeds.
    Any Julia set is determined by a seed. Interesting seeds are boundary points of the quaternion mandelbrot set, so QJN lets you browse the quaternion mandelbrot set to get these seeds (yes, this set is four dimensional).
  2. Lighting.
    QJN is built around a sophisticated ray tracer. It lets you set the ambient light level and the intensity of a spotlight.
  3. Shadows.
    The spotlight throws shadows. QJN can render those too!
  4. Textures.
    QJN lets you apply any BMP image as texture to the fractal. You can also use any BMP file as background of your image.
  5. Rotating.
    Want to look at the fractal from another angle? Simply rotate the fractal with your mouse.
  6. Loading and Saving.
    Of course you can load and save images. Only BMP format is supported in the current release.
  7. Stereo images.
    Want to see the images in real 3D? Put on your red/green stereo glasses and let QJN render a stereo image. Impressive.
Well, you say, this all sounds a bit complicated... Don't worry, QJN makes it easy for you and you will be rendering images within no time.

SYSTEM REQUIREMENTS: You will need a PC running Windows 95/98 or Windows NT with at least 16Mb memory. The faster the machine the better, but it will run on a 486. To get quality pictures on your screen, make sure Windows runs in 16bit colour or higher.
