Re: [osg-users] Android Development Plans

OpenCV is Android port is more cleaner than the use of toolchain that we are using right now. Working with the Cmake toolchain there were some files that Cmake won't ever find, even if they were. With this other approach, this should not happen because you use Cmake to generate the Android Makefile

Hello Thomas, I'll keep you up dated Thanks. One thing I just remembered, I don't know if you'll be using the Eclipse-based toolchain that Android provides, but I found sometimes when I changed the jni lib (and recompiled it from the command line) the Eclipse plugin wouldn't pick up on it b

Re: [osg-users] osganalysis.cpp getNumTextureAttributeLists?

Hi Robert, It's not quite that straight forward... as per texture unit there is a whole AttributeList and ModeList assigned to it, so number of texture units != number of texture modes or texture attributes. The name as checked in correct, there is also already checked in an explanation. Ah

[osg-users] Visibility of point array

Hi, I am trying to detect which of a set of 3D points (e.g. vertices of a scene model) are currently visible. I tried to derive from osg::Geometry and overwrite the drawImplementation methode. The _vertexData.array contains all points specified (all points, also the occluded) and _vertexData.in

Hi Lucie, I haven't tried it out but it looks like in the inner for loop, numSegments is defining how many panels it takes to complete a circle. If you iterate only until numSegments/2 it might give what you're looking for? Code: for(unsigned int topi=0; topi < numSegments/2; ++topi,angle+=a
