I followed the instructions in the README prior to posting this, but was still having problems. I moved the osgdb*.dll files to the directory where my examples live. osgppu_viewer runs now, but the osgppu_video is still complaining about not finding the plugin it needs. Which particular plugin does it need? W On Mon, Nov 2, 2009 at 8:28 AM, Art Tevs arti_t...@yahoo.de wrote: Hi Wyat, WyattEarp wrote: What is the cudakernel project that Cmake generated?

Re: [osg-users] [osgPPU] I have an OSG app to which I would like to add a second render pass...
I think I found the problem why the plugin isn't found... Is the plugin for playing avi the QuickTime plugin? If it is, it isn't building built when I build OSG. I ran CMake and see that the QUICKTIME_LIBRARY and QUICKTIME_INCLUDE_DIR are NOTFOUND. I assume this is the reason the qt plugin isn't being built. Is that the case?

Re: [osg-users] [osgPPU] I have an OSG app to which I would like to add a second render pass...
Which plugin is exactly used, is actually not dependent on osgppu. It just uses osgDB to load an .avi file. In earlier versions of osg a quicktime plugin was used to play .avi files, right. I don't know exactly the version number, but in between there was a change to ffmpeg plugin. I am also not sure if ffmpeg is built on windows at all. So, if video example don't work, then just ignore it, if it is sufficient for you. It could be that you would require couple of additional libraries to built osg's video plugin on windows. Maybe search in forum or on the mailing list archives to find mor einfo, how to use video playback in osg on windows. cheers, art WyattEarp wrote: I think I found the problem why the plugin isn't found...

Re: [osg-users] [osgPPU] I have an OSG app to which I would like to add a second render pass...
Hi Wyatt, The main idea of osgPPU is to use input textures to process them. This can be used for rendering as also for GPGPU. Take a look into HDR and Video examples. In the first one the input color buffer of the camera is used to apply HDR tone mapping and glow effect and then render it on the screen. In the second example input texture is used to be processed and then used as a texture on some quad. So as you can see, one can use osgPPU not only for outputing results to the screen but also to process a texture in between and then use it in usual rendering. regards, art WyattEarp wrote: Hi, I have an OSG app to which I would like to add a second render pass. I render to a fbo hdr texture and I want to use a 2nd pass to process this texture, then write out to another hdr texture, then display. Is this the sort of thing that osgPPU is meant for?

Re: [osg-users] [osgPPU] I have an OSG app to which I would like to add a second render pass...
The error is that osg installation could not be found. Check that you have osg also installed. The svn version of osgppu does only work with the current svn version of osg. If you have older osg version installed, then get the according osgppu version either from the svn tags repository or directly from osgppu webpage (projects.tevs.eu/osgppu). Check also that CMake was able to find your osg installation. If you can see cmake variables like OSGxxx_LIBRARY_RELEASE set to NOT FOUND, then CMake was not able to find the installation. Then you have to set OSG_DIR variable to the path, where osg is installed in order to let cmake find it. cheers, art WyattEarp wrote: I download the latest code from SVN, ran CMake to generate the proj files, and tried to build it.

Thanks, I am using OSG 2.8.0 and the osgPPU from SVN. Is that a problem? Also...
