What are the symtoms of not rendering correctly? Can you provide a PAR?
Apologies for being obscure, I somehow had the impression of this being a known bug. PARs follow beneath this text. Both "Quat-Test" and "Hyp-Test" PARs are set up in a way the resulting 3d slice of the 4d-Mandelbrot set should be easily recognizable if rendered correctly (its silhouette resembling the well known 2d version, the complex M-set). Load, say, "Quat-Test": Instead of the above, Fractint outputs a sphere. Now load "QuatJul-Test": This produces the quaternion version of what Mandelbrot called the San Marco Dragon. Press <z>, switch from quatj to quat, press <Enter>. Although we are now in a mandelbrot routine, again we get the San Marco Dragon! The equivalent applies to "Hyp-Test" and the hypercomplex types. And... even going from (one type) julia --> (other type) mandelbrot, one gets the (other type) julia with the same parameters! Hope this helps a bit more, Gerald ---------------------- Begin of PARs ----------------------- Quat-Test { ; Fractint Version 2003 Patchlevel 1 ; reset=2003 type=julibrot julibrotfromto=-1.5/1.5/0/0 julibroteyes=2.5 orbitname=quat corners=-2/2/-1.5/1.5 params=0/0/0/0 float=y } QuatJul-Test { ; Fractint Version 2003 Patchlevel 1 ; reset=2003 type=julibrot julibrotfromto=-1.5/1.5/0/0 julibroteyes=2.5 orbitname=quatjul corners=-2/2/-1.5/1.5 params=-0.75/0/0/0/0/0 float=y } Hyp-Test { ; Fractint Version 2003 Patchlevel 1 ; reset=2003 type=julibrot julibrotfromto=-1.5/1.5/0/0 julibroteyes=2.5 orbitname=hypercomplex function=sqr corners=-2/2/-1.5/1.5 params=0/0/0/0 float=y } HypJul-Test { ; Fractint Version 2003 Patchlevel 1 ; reset=2003 type=julibrot julibrotfromto=-1.5/1.5/0/0 julibroteyes=2.5 orbitname=hypercomplexj function=sqr corners=-2/2/-1.5/1.5 params=-0.75/0/0/0/0/0 float=y } -------------------- End of PARs -------------------------
