[osg-users] Video textures on iOS (and audio)

Hi, I wonder if playing a video texture (from a .MOV file) with OSG for iOS works the same way as OSG for Mac OS X...I mean, is it enough to build the osgdb_qt library and statically link to it? Would this work for iOS too? What about any audio eventually embedded in the .MOV? Thanks.

I'm glad there's a topic on this! I encountered the same osgText problem yesterday. I have some osgText::Text labels with their character size mode set to screen coordinates and their axis alignment set to screen that weren't showing up when we moved from osg 2.8.2 to osg 3.0.0. As a

Re: [osg-users] [Need Help] Entire 3d environment needs to be bump mapped.

Dear Zach, The older post are right. For bump-mapping, you'll need two things: a bump mapping shader and a normal map texture for each of the objects you'd like to bump map (assigned to a different texture unit than your diffuse texture, e.g. unit 1). The good thing of the scene graph

Re: [osg-users] RTT into a single color channel

Hi Mark, JP, I think easiest would be to render to 3 luminance textures and then combine in another step into rgb. Why not render 3 passes into the same RGB texture but just write to one channel per pass using color masking? You'd save the combine pass. J-S --

It looks like the bounding box is not being calculate correctly, but if the bounding box can be drawn when using SCREEN_COORDS correctly, why can't the bounding box be returned correctly? Kurt -- Read this topic online here:

Re: [osg-users] RTT into a single color channel

I like the idea of combining the passes into one, but if I had a blue object and had to mask it into the red channel, wouldn't it just be black? I had talked to a professor who had suggested a one-line fragment shader to do RGB- Luminance and use Color Masking to write into the appropriate

Re: [osg-users] osgText SCREEN_COORDS picking problem

Hi Kurt, osgText bounds seem to be an ongoing issue. There have been some changes made since OSG 2.8, so you should probably try using the trunk and see if it behaves differently. Here's some possibly (but probably not) related reading: http://www.openscenegraph.org/projects/osg/changeset/12467
