Attractor Parameters

The different elements displayed in this tab are:

  • Render Mode - the most important setting: It specifies how ChaosPro should render the object. The "light" column in the following table shows which render mode uses light settings. As you can see, only the "Solid" algorithm. This is no surprise, as in all other cases the render mode does not actually calculate any surfaces and thus cannot calculate light intensities.
    ModeLight?Description
    GasNoThe object is assumed to be gas like. Light settings have no effect. The object is rendered according to the hit count of each pixel, just with gas, where it seems to be transparent where only a small amount of gas is and it seems to be more opaque if there is much "gas".
    FlameNo

    Renders the object using the flame algorithm, i.e. some kind of log-density is calculated and the image is rendered according to that.

    You need to use a proper coloring formula in order to take full use of this rendering mode. Although it works without assigning the correct coloring formula, the coloring formula "FlameSequence" produces good results.

    PlasmaNoModification of the flame algorithm: Produces sometimes better results, and sometimes not.
    SolidYesAssumes the object is solid. Tries to find surfaces and surface normals, calculates light intensities which fall onto the surfaces.
  • Preview Pixels - the OpenGL preview rendering mode will render as many pixels as are specified by this setting. If the object rendered by OpenGL seems to be too "thin" and you can't see a reasonable preview of the fractal you might want to increase this value. But of course, the higher the setting, the slower the OpenGL preview mode...
  • Threshold - A pixel on the screen will be rendered only if the hit count is higher that this value. So if single pixels outside the fractal object appear, you might want to increase this value in order to get rid of them.
  • Weight Radius - Belongs to Threshold: A pixel normally will add a single point to the pixel on the screen. If weight radius is greather than zero, the hit count of neighbouring pixels will also be increased.
  • Roughness - lets you specify an artificial roughness of the surface by modifying the angle in which the light falls onto the surface. If you set it to 0.1 then the surface seems to be a little bit rough. 0 turns roughness off, the pure fractal surface will appear without any special modification.
  • Opacity - defines how opaque the object will be. The setting is available only for render mode Plasma and Solid. If you set it to e.g. 100 or higher, the object will be opaque. Setting it to 10 makes the object a little bit transparent. The smaller the value the darker the image, as the object itself will be more and more transparent and thus no light is reflected.
  • Gamma - the gamma value: If the object seems to be too dark, it's a good idea to adjust the gamma value and make it smaller.
  • Contrast - lets you adjust the contrast of the image
  • Brightness - The setting is available only for render mode Flame. It lets you adjust the brightness of the fractal rendered in "Flame" mode.
  • White Level - The setting is available only for render mode Flame.
  • Filter Radius - Lets you apply a gaussian filter to the image. If set to 0, no gaussian filter will be applied to the image. If not 0, a gaussian filter will be applied and thus the image will appear smoother. This setting is especially useful if Oversample is set to > 1: The final image then is downscaled and a filter is applied, thus the image appears smoother.
  • Oversample - lets you artificially increase the image size: The Attractor will be calculated in a higher resolution. At the end it will be down-scaled to the actual size.
