Release 4.0

Predefined Parameters : Quaternion

Fractal type Quaternion also has several predefined parameters partially depending on the formula type. They allow you to access some quaternion specific variables like the basis of the three dimensional subspace of the 4 four dimensional quaternion space or the 3D pixel which currently gets examined.

The following parameters exist:

Transformation Iteration Coloring     alpha real r/w real r/w real r/w     Base1 quaternion r/o quaternion r/o quaternion r/o     Base2 quaternion r/o quaternion r/o quaternion r/o     Base3 quaternion r/o quaternion r/o quaternion r/o     Base4 quaternion r/o quaternion r/o quaternion r/o     Basepoint quaternion r/o quaternion r/o quaternion r/o     e real r/o real r/o real r/o     height real r/o real r/o real r/o     index - - - - - - real r/w     maxiter real r/o real r/o real r/o     Normal quaternion r/o quaternion r/o quaternion r/o     numiter real r/w real r/w real r/w     pi real r/o real r/o real r/o     pixel complex r/w complex r/w complex r/w     pixelcolor - - - - - - color r/w     random complex r/o complex r/o complex r/o     randomrange int r/o int r/o int r/o     screenmax complex r/o complex r/o complex r/o     screenpixel complex r/o complex r/o complex r/o     solid bool r/w bool r/w bool r/w     width real r/o real r/o real r/o     z quaternion r/w quaternion r/w quaternion r/w

The table lists the datatype of the predefined parameter and one of the following abbreviations:

• - - -: not available
• r/o means: read-only
• r/w means: read-write
• w/o means: write-only
