The Calculation Depth slider controls how many iterations are calculated before filling a point with the background color. The number of iterations is automatically adjusted when changing the zoom level.
The Detal Level slider controls how much details of the fractal are calculated. Parts containing few details are skipped for faster generation.
The Anti-Aliasing option controls the post-processing level of the image which makes it look more smooth in areas containing many details.
The Mesh Resolution option controls the resolution of the fractal rendered in 3D mode. Higher resolutions require a fast graphics card.
The Mesh Height Scale slider controls how much the mesh is stretched vertically.
The Camera Zoom controls the zoom of the camera, making the mesh appear closer or farther.
