[osg-users] SubloadCallback and PBO cleanup

Hi all! In my OSG application I need to continuously update small parts of 2D texture. So I use osg::Texture2D::SubloadCallback: class MyCallback : public osg::Texture2D::SubloadCallback { /* initialize texture */ void load(const Texture2D texture,State state) const {

Re: [osg-users] [build] undefined symbol: _ZN11OpenThreads6AtomicmmEv

Hi Huron, I've experienced the same problems with unresolved symbols from OpenTreads. The problem was solved by full rebuild of OSG. Just delete CMake cache, reconfigure and build. Once I've fought unexpected runtime errors (segmentation faults) in simple OSG apps (even in examples) and they

Hi All Consider we have a lot of points in 3D and we need to render some additional information around them in screen space. For example, for very 3D point we need to render rectangular panel (with dimensions Mpx x Npx), line from this panel to the point in 3D and some text on the panel. So we

Re: [osg-users] 1-bit texture for shader

Hi! You can use 8-bit mask texture filled with zeros and 0xFF's (like your bitmask). Then just multiply texels of source texture and mask texture. Texture format could be GL_ALPHA and internal format - GL_ALPHA8. ___ osg-users mailing list
