Figure 11.132.  Example of a rendered Flame.

This filter is found in Filters → Render → Nature → Flame

With the Flame filter, you can create stunning, randomly generated fractal patterns. You can't control the fractals as you can with the Ifs Compose filter, but you can steer the random generator in a certain direction, and choose from variations of a theme you like.

In the main window, you can set Rendering and Camera parameters. The first three parameters in the Render display are Brightness, Contrast and Gamma. The result of these options is visible in the Preview window, but it's generally better to stick to the default values, and correct the rendered image later with Image/Colors.

The other three parameters affect the rendering process and don't show in the preview window. Sample Density, which controls the resolution of the rendered pattern, is the most important of these. The Camera parameters allow you to zoom and offset the flame pattern, until you're happy with what you see in the preview window. Flame also offers the possibility to store and load your favorite patterns.
