Hi,
Instead of trimming [0] from the name, as previously suggested, we should
detect if a uniform name has it, but add BOTH 'name[0]' and 'name' into
Program::_uniformInfoMap, so that when the osg::Uniform are applied, there will
be a name match for whatever the driver returns... Both are actually valid.
The fix I have applied in my osg version, in
void Program::PerContextProgram::linkProgram(osg::State& state)
// For some drivers, active uniform array names are returned as 'name', and for
others, 'name[0]'
// The way OSG works is to lookup into the program's active uniforms to see if
a uniform set in a StateSet
// is present, and apply it only in that case. But that mechanic fails if the
active uniform name
// includes the backets, but not the other, and vice-versa. So add both into
the _uniformInfoMap
// to fix this, as both names are valid and allowed by OpenGL specifications
std::string strName(name);
if(strName.length() > 3 && strName.substr(strName.length()-3, 3) ==
std::string("[0]"))
_uniformInfoMap[strName.substr(0, strName.length()-3)] =
ActiveVarInfo(loc,type,size);
Thank you!
Cheers,
Philippe
