• Customisable: Resize, reorder, and recolour fractals on the fly. You can also adjust the number fractal iterations.
• Expandable: Easily add definitions for generating new fractals through a simple-to-use extension system.
• Performant: View complex fractals with up to 15 iterations with a high framerate.

Download a build from the releases page.

• Create new fractals using the Select Fractal dropdown
• Select a fractal using its button to set the camera orbit to that fractal
• Right click and drag to orbit around the currently selected fractal
• Use the scroll wheel to zoom in / out of the currently selected fractal
• Change fractal colour using the C button
• Remove a fractal using the - button
• Change the base length of a fractal using the length slider
• Change the number of fractal iterations using the iterations slider
• Change x, y, z coordinates of the fractal using the x, y, and z sliders accordingly
• Adjust the background colour using the Background Color button
• Export the current scene with the Export PNG button
• Return to a 'home view' using the Home View button
• Exit the app using the escape key

Due to how meshes are combined, for any fractal, there will always be a limit of 2^32 vertices. This means a maximum of 15 iterations for the Sierpiński tetrahedron fractal, and this number will reduce as the number of vertices per each fractal generator increases.

Unfortunately for some devices, the max number of vertices per mesh supported is only 2^16, since not all GPUs support a 32 bit mesh index format. FractalStuff forces this limit to 2^32 to support higher numbers of iterations, but this means that some devices just won't be supported.
