Mandelbulber 1.20Open source program (GNU GPL) for rendering photo-realistic 3D fractals Free download (executables and source): http://sourceforge.net/projects/mandelbulber/Website: http://www.mandelbulber.com/User manual: http://wiki.mandelbulber.com/index.php?title=User_ManualNew features in version 1.20:- OpenCL - added NoDE rendering engine - OpenCL - added "limits" feature to rendering engine - OpenCL - added "interior mode" - OpecCL - added primitive objects - OpenCL - next trial to fix the problem with -I option for OpenCL compiler (spaces in path were not passed properly). I hope this time it is permanent fix. There is used completely different method to pass include path. - OpenCL - added setting for delta for deltaDE algorythm - added HUD for flight path recording - simplified code and corrected for "limits" and "interior mode" - fixed bug: NetRender didn't worked under Windows 7 and Windows Vista. Now connection is limited to IPv4 and works properly. - fixed problem with visibility of 3D cursor during flight path recording - fixed resource leaks Example of primitive object - water, used with Monte Carlo DOF  Example of "limits" and "interior mode"  SVN repository: http://mandelbulber.googlecode.com/svn/trunk/This repository is available from Google Code: http://code.google.com/p/mandelbulber/

Thanks Buddhi, openCL now runs on my CPU Intel i3 2.13 MHz
For attached example:
Not openCL 39sec,
openCL Full: all shaders 22 sec,
openCL Normal 5 sec (wow)
openCL fast 4 sec compared to 13 sec without openCL
Some minor to major colouring differences
Runs on AMD platform but not on Intel platform (error -11),
OpenCL Build log: Compilation started
:318:10: error: cannot combine with previous 'type-name' declaration specifier
:318:15: error: expected identifier or '('
:319:8: error: expected identifier or '('
:320:32: error: expected expression
Compilation failed
whereas all CL CPU demos on Geeks 3D GPU Caps Viewer 1.19 work on the Intel platform, but this is all way beyond my limited knowledge ( I do note there are differences with the openCL extensions between the two platforms)
Lots of crashes with hybrids but oops just read post on hybrids
overall its great when it works. I suspect that when I upgrade my laptop and can use the GPU I may not have any problems.
Thanks again.

Thanks for reporting this problem. You were right. There is a difference which should't be. OpenCL code uses fixed_radius parameter in wrong way. In OCL code for mandelbox there is: if (rr < mr2) m = native_divide(scale, mr2);
else if (rr < fr2) m = native_divide(scale,rr); should be: if (rr < mr2) m *= native_divide(fr2, mr2);
else if (rr < fr2) m *= native_divide(fr2, rr); P.S. Next time when you paste parameters use [ code ] [ /code ] (# button in editor menu) or attach it as a text file. |

Thanks for showing the corrected code. It gave me enough confidence to update the cl files myself  rather than waiting for the next version release.  Another thought, if Custom Formulas Example 1 is based on the Mandelbox, should it also have m *= native_divide(fr2, mr2) and m *= native_divide(fr2,rr) in the code? |

In every OpenCL script is the same mistake |

OpenCL 1.0 did not support "float3" type. That was added in version 1.1 later. Can you find out the OpenCL version that your GPU (or the device driver, respectively) supports?

Can't seem to get the ATI card selected when I enable OpenCL, no matter what I set for Platform/Device it keeps selecting the primary Nvidia card and resetting Platform/Device to 1/0. Was working in 1.9.
Edit: Seems to do it if I do 0/0 (didn't think zero was a possible option for platform since 1 was default)

Platform #1 was last saved value (default is 0). You must set it before (e.g. when you used 1.19). Program saves setting when application is closed, so for you default was 1  |

@ Hobold. Thanks for pointing me in the right direction. I now see that even though the platform is 1.2, my GPU device can only handle 1.0. If it looks like your GFX card doesn't support OpenCL 1.1, try to upgrade drivers. Sometimes it is not a matter of card but software. It is worth to try. |

Hi, Hint -> it would be nice to pointing , that the GPU musst handle OpenCL V1.1 or higher at last ....(if this not changed) So bug reports/errors that come from this side can be closed Regards R-TEAM |
