Hi Art, > Cool, I am glad to hear that the library also runs on > another machines. my Hardware at home is not the best for testing this (AGP8x, 7600GS) , but soon I will try get a new system with 2x 8800GT and a mainboard with 750i SLI Chipset. Today I can only render 512x512, else the framerate is going down under 10 Hz. It should run much faster on a new system.

When using the osgPPU lib for applications, it seems for me that a little bit training is required to get predictable and good results when combining and reusing lots of units. I tried to change/animate some parameter/uniforms to find out how it works. Changing some of the PP-Unit's index was a funny experiment. > Because you like > to implement another testing application you can try > to implement the depth of field effect.

Hmm, it was not difficult to get your lib built and running, but I'm affraid that I have to study about "Light Physics" first, before I can contribute to implement such Effects like "Eikonal Rendering". At the moment , unfortunately there is not enough time for starting advanced stuff because of job and family. I just try to follow the current osg-development. For making users more familiar with osgPPU, maybe there is a need for a GUI application - like a "osgPPU Browser" with embedded osg-viewer. I can try starting such Project after work for learnig more about uses of osgPPU. Personally, I think that interactive control and animation of shader parameters, unit index etc. could be helpful for osgPPU users under application development. > Currently I have to prepare some video sequences for > the upcoming Siggraph deadline, therefor I do not have > a lot of free time to improve osgPPU. I don't want to stop you :-) Interestings papers and videos on the "Eikonal Rendering" project-page Regards, Markus _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
