Program

AQ Fractal is a Mandelbrot fractal explorer program written in Javascript. It is designed to run in a web browser.

• Frames can be exported as PNG files.
• Uses WebWorkers for multi-threading. Allows faster performance.
• Optional fixed-point math for arbitrary-precision for virtually unlimited zooming.
• Easy to modify template to incorporate into other web interfaces.
• Client-side only operation. No server required.

Manual

• Navigate by hoving over an area to zoom. Click to zoom to that area.
• Click and drag to select an area to zoom.
• Right-click to zoom out.
• Hold Ctrl when clicking to center the image at that location.
• Hold Shift when clicking to pan the image.
• To return to the top-level, hit the Reset button.

Iterations

The fractal equation works by running a function until it exceeds a specific value, or a maximum number of iterations has been reached. To get more detail as you zoom, increase the max iterations. This requires more compute time but will fill in more of the black area.

Color Palette

The color palette is randomly generated. To generate a new palette, hit the Palette button.

The palette uses a coarseness level to generate the palette. This defines how fast the colors are allowed to change. The higher the coarseness, the fast the colors can change. For deep zooms it is often useful to lower this value so the colors do not become a mess.

Saves

The Save button will render a larger image and prompt it to be saved to disk. The Save size multiplier tells the render engine how much larger the finial render will be than the view size.

Arbitrary-Precision Math

This fractal explorer has arbitrary-precision math. When zooming into the fractal the number will get as small they will no longer be able to generate an image. To address this, arbitrary-precision fixed-point math can be used to compute the fractal. It is slower, but with a large enough shift (and enough time and memory) the zoom is unlimited.

By default, Auto percision mode is enabled. This is a toggle button and green when enabled. This will automatically increase the percision when more is needed.

You can choose to manually operate percision. Floating-point mode is good for around 10 tillion times zoom. The switch can be made by hitting the Float button. When in fixed-point mode, more/less percision to the numbers can be given by using the fixed-point shift increment/decrement buttons.
