Glass Hemisphere

Ultra Fractal glasshemisphere Glass Hemisphere

The Glass Hemisphere transformation displays the fractal as though it is viewed through a spherical lens. It is available as a transformation in Standard.uxf and as a transformation plug-in in Standard.ulb.

The location, size, and apparent refractive index of the lens can be changed. The refractive index adjusts the strength of the lens.

The following parameters are available:

Refractive index

Specifies the refractive index of the lens. You can use this to simulate various glass-like materials. Larger values will increase the strength of the lens.


Specifies the width of the lens in fractal coordinates.


Specifies the coordinates of the center of the lens. Use the eyedropper (right-click and click Eyedropper) to select the center by clicking inside the fractal window.

Use Screen Center

If checked, the center of the screen is used instead of the Center parameter, so the lens is always centered on the screen, even when zooming in.
