![]() As soon as you select such an entry you get asked whether you want to convert this fractal type. Some special processing occurs to entries in *.par files which use the fractal type "Formula". But ChaosPro silently removes such entries and places a message into the message window that it cannot load that entry. Because FractInt supports numerous fractal types and not all fractal types have been built into ChaosPro, not all entries in a par file can be processed by ChaosPro. Additionally ChaosPro can load many *.par file entries from FractInt. Problems occur with ChaosPro V2.0 *.frm formulas if you used the additional coloring feature of ChaosPro: These formulas cannot be converted to the compiler, because the compiler and the corresponding fractal type Escapetime work with iteration formulas and coloring formulas, thus one formula would have to be split into two formulas, which would have to belong together.ĬhaosPro can load all old ChaosPro *.par files. Normally ChaosPro should be able to read all FractInt *.frm files. If you load *.frm files using the old formula editor then they will be loaded only into the formula editor.Īt startup all formulas found in the formula directory are loaded into the formula editor as well as transformed and inserted into the compiler window. If you load *.frm files using the Open-command of the formula compiler, then these formulas will be loaded only into the formula compiler and will be transformed into the ChaosPro compiler syntax on the fly. Unfortunately even the user of such a formulaĬannot easily decide whether the final image is just the result of illegal numbers or a real fractal.ĬhaosPro has a formula parser and a formula compiler. The fault of ChaosPro, but basically the fault of the formula writer. Neither UltraFractal nor ChaosPro do active checking for illegal numbers (infinity, NaN, etc.),Īnd so the result of a function or operation applied to an invalid number is undefined and in fact different in both programs.Įven future releases of UltraFractal most likely will render fractals based on such formulas differently. On the other hand, ChaosPro won't be 100% compatible to UF3:įormulas which produce illegal numbers. If you encounter any problems (fractals look different in UltraFractal Now lets continue discussing compatibility issues:ĬhaosPro 3.1 tries to be fully UF3 compatible. I would remove that bug without trying to retain Now suppose the sin function in ChaosPro had a bug. ![]() Sometimes fractals will look different in a new version: This may happen if a function had a bug. So you should be able to read old ChaosPro formulas At first, ChaosPro tries to be compatible to itself (of course). ![]()
