ChaosPro is a MDI fractal generator using "multi threading".
It is completely based on 24 bit. ChaosPro can read FractInt and UltraFractal parameter, palette and formula files, and is supporting many of FractInt's fractal types as well as UltraFractal formulas.
The program lets you write your own formulas in a language similar to C/C++. A built in compiler speeds up the fractal calculation.
It has support for layers (similar to Photoshop), has alpha channel support (even per pixel), and thus lets you combine fractals and coloring formulas to build new fractals.
ChaosPro is able to create animations by using a keyframing technique, allowing to animate almost every parameter.
It lets you 3D transform a 2D fractal (height fields) and supports 3D fractals directly (Quaternions).
