Re: [osg-users] ffmpeg stdint on Windows?

Hello All: If you are going to build it from scratch I have better luck making sure that you disable mmx and mmx2. This is a killer to get to build sometime. I get local registers getting clobbered errors when using their assembly enhanced code routines and if the mmx acceleration is us

Hello All: The link below is the one I used before to add stdint.h and inttypes.h. I use it for the builds on windws. I have sucessfully used mingw then use Microsofts implib tool to create a import lib for the dll. Like they said below. ffmpeg will not build on MSVC and even if you

Additional information. The error is looking for files in osgIntrospection. I do not see this in my osg install directory. However, I had no errors on the build of OSG or the install and none on VPB. Michael On Fri, 2009-07-10 at 17:05 -0500, Michael W. Hall wrote: > Can someone help me out wit

Re: [osg-users] what is the thread difference between MFC andconsole?

Ümit Uzun, I would suspect that the problem you described is related more with you graphics card then with the size of the window you are rendering into. It sounds like, in your case, the larger window size would cause more raster operations to be performed, while decreasing the size of the w

Hi Paul, Has anyone successfully built the ffmpeg dependency on Windows? Once built, were you successful in getting OSG's CMake to produce a ffmpeg plugin project file? We just used prebuilt binaries of ffmpeg (non-GPL). Perhaps you could use them too? I think you could search for ffmpeg-r15

Hi, does anyone know if it's possible to run faster than the 60Hz vsync or 100Hz osg limit, if computational performance is the ultimate goal even at the expense of "tearing." Can I get 600 fps by turning off vsync (or something else, it didn't work on my box)? Is the graphics card driver/model i

Hi Wojtek, You got me. Say magic word "shadow" and I will crawl up from my den ;-) :-) Actually, I like the approach with node names and I don't think this is a hack. Node naming is possible in many modelling tools and this is what make them quite useful. We often use names to mark specia

Re: [osg-users] how to set per vertext attributes using osg

Hi Jason, OSG sorts by state to minimize state changes, but I'm not sure how it does the sort. I believe the state sort is done using the compare() method of StateAttribute. In the case of Uniforms, the comparison is pretty thorough (first data type, then number of elements, then actually

Re: [osg-users] how to set per vertext attributes using osg

Hi Colin, Attributes provide a faster way of changing vertex properties even on a per object basis, as it means all of your objects can share the same state. Changing the value of uniforms cause the creation of a new state. Lots of state changes can be very expensive. Sure, but some types of s
