Development of Mandelbulber 2.18 was mostly focused on implementation of stereoscopic rendering in OpenCL mode.
This new version got very interesting "fake lights" effects based on calculation of different shapes of orbit traps.

Download from: https://sourceforge.net/projects/mandelbulber/
GitHub: https://github.com/buddhi1980/mandelbulber2



New in 2.18:

- Added new fractal formulas
   amazingSurfMod3
   transfRotationIterControls
   transfClamp4d
   transfAbsAddMulti4d
   transfRotateAboutVec3
   transfOffsetSCurve4d
   transfGnarl
   transfBoxTiling4d
- modified fractal formulas
   menger middle mod, added vary scale and sphere inversion
   trans_scale4d,  added vary scale
   aboxModKaliV2,  added oldZ sign transform
   transfAbsAddTgladFold4d, added iter controls and aux.color
   transfBoxFold4dTglad, added linear vary scale option
   mandelboxVariable, added variable functions for box limits and addCpixel
   aboxModKali, added pre-rotation (variable)
   transfQuaternionFold, re-structure DE
- OpenCL: Added rendering of stereoscopic images
- OpenCL: Disabled loading of textures in fast and medium OpenCL modes (improves performance)
- OpenCL: Fixed problem with "nan" estimated noise when some of pixels have infinite brightness.
- OpenCL: Added missing code for DeltaDE josKleinian. Fixed bug #627
- OpenCL: Corrected displaying of total rendering time when DOF is used
- OpenCL: Added more logging to OpenCL launching code.
- Effects: Added rectangle, circle, cube and sphere shapes to "fake lights" algorithm
- Effects: Added "thickness" parameter for "fake lights"
- Effects: Added reduction of stereoscopic effect on poles when is used equirectangular projection
- Effects: Swapped eyes in top-bottom mode (default was incorrect when uploaded into Youtube)
- Effects: Added button "Calculate optimal distance between eyes" for stereoscopic rendering
- Effects: Fixed bug in openCL multi-ray AO #634. When iterThreshMode was enabled, the detailLevel parameter was still used.
- Effects: Added elimination of calculation of DOF at pixels with zero distance
- Settings: Corrected loading of settings with animation containing parameters with names *_x, *_y, *_z, which are not vectors
- Files: Added saving metadata (scene parameters) into image files.
- Files: Fixed bug #637. Now files from _alpha and _zbuffer directories are deleted.
- Files: Added saving 8-bit JPG z-buffer
- UI: Corrected behavior of "Default window layout"
- UI: Disabled auto-refresh before settings are loaded (fixed problem with partial loading of settings)
- UI: Better handling for "Material is not defined" problem. Fixed issue #636
- UI: Added displaying of path to log in Preferences.
- UI: Added option to enable/disable rendering of thumbnails (used in load settings file selector)
- UI: Fixed bug #654. Now central widget is not hidden when rendered image is detached.
- UI: Fixed problem with unwanted repeating of rendering after mouse dragging.
- Fractals: Added advanced controls for raymarching step calculation.
- MacOS: fixed OpenCL compiler errors caused by missing line breaks after last lines of code
- MacOS: Eliminating error on MacOS: Critical: OpenCl ERROR: "Device #0: cl::CommandQueue()" ( -30 )
- MacOS: in mac/build_deploy.sc corrected copying of share folder (now default textures works)
This change doesn't have impact on rendering speed.
- Compilation: Added 'make install' option for qmake
- Compilation: Added support for running Mandelbulber as portable application under Linux
- Compilation: Added continuous integration for AppImage
- Compilation: Fixed bug #655. Corrected paths tof doc and data in prepare_for_dev* scripts

Nice new formulas and the new fakelights are really awesome and a joy to play with! Thanks for the good work!
