For this version I made a lot of internal refactorings to improve rendering quality and hybrid-fractal-support. Also, there is a new experimental hybrid-container which uses a variation- or scalar-field to modulate the iteration-counts of the fractal formulas inside the hybrid. This creates coordinate-dependent hybrid-geometry. It is a little bit hard to setup, but a lot of fun to play with.
Complete changelog:
VERSION 3.44.2717 (10.05.2026):
- mandelbro3d:
- experimental: add new Weighted Alternating hybrid container, which uses a scalar field to
modulate individual formula iteration counts (SWAN-1541)
- dIFS-style-fractals do work inside hybrids (SWAN-1542)
- fixed: when rendering an animation in Z-Buffer mode all frames were black (SWAN-1535)
- when switching between objects, try to keep the selection of the current sub-tab (when it exists) (SWAN-1532)
- added "Quadrat3D"-formula (SWAN-1539)
- moved the bail-out-attribute to the formula-level (SWAN-1538)
- fixed problem with hollow shadows on non-IFS-power-fractals (SWAN-1537)
- added "Koch Surf"-formula (SWAN-1524)
- fixed: some sky-objects still show a disc-like shape (SWAN-1540)
- simplify Iterations-handling and move the parameter to the formula-level for all different cases (SWAN-1543)
- added new "Polytope Folds"-formula-categor and move the matching formulas there, like e.g. "DIFSCross" (SWAN-1544)
- added "InvSpherical" formula (SWAN-1545)
- added "Transform"-formula (SWAN-1546)
VERSION 3.43.2704 (08.05.2026):
- mandelbro3d:
- added "Box Fold Bulb Pow2"-formula (SWAN-1523)
- fixed: procedural textures on hybrids caused a shader compile error (SWAN-1525)
- fixed: plain object-emission (without textures) had stopped to work (SWAN-1526)
- fixed: procedural textures were sampled in world space, not in orbit space (SWAN-1527)
- fixed: Julia-Mode did not work at formula-level inside hybrids (SWAN-1528)
- renamed "DE Factor" into "Pixel-Cone Tolerance" which is much more precise (SWAN-1529)
- reduced false shadows when reducing DE Multiplier (SWAN-1530)
- fixed: editing numbers in the motion-curves-editor sometimes causes change of the preview
(because it receives the key-strokes) (SWAN-1531)
- fixed: texture emission white screen (SWAN-1533)
- animation-renderig: also added "Wireframe" as possible render-mode (SWAN-1534)
