Thanks Mourad,
That solves my problem. I saw this method used inside the code but did not
notice it is static so I thought it can be used only when we know the uniform
ptr.
Do you think it makes sense to add following extra method to PerContextProgram ?
inline GLint getUniformLocation( const std::string & name )
{
return getUniformLocation( osg::Uniform::getNameId( name ) );
}
Cheers,
Wojtek

Subject: Re: [osg-users] osgCal does not build - where is
PerContextProgram::getUniformLocation( string ) method ?
Hi Wojciech,
This change was introduced in rev 11952. This new static function in
osg/Uniform should help you to get the (unsigned int) id out of the (string)
name :
static unsigned int getNameID(const std::string& name);

Hi Guys,
The title says it all. We use osgCal and it does not compile anymore.
Compiler does not find Program::PerContextProgram::getUniformLocation( const
std::string & ) while compiling HardwareMesh.cpp. Problem appeared with trunk
change revision 11942:
Where
Program::PerContextProgram::getUniformLocation( const std::string & )
was replaced with:
Program:: PerContextProgram::getUniformLocation( unsigned int )
I tried to look at modified PerContextProgram to figure out how to get
uniform location knowing only uniform name but I was not able to come up with
reasonable idea. Can anyone help me ?
Ideally we could possible retrofit PerProgramContext with a method that would
accept string name ? It does not mean reverting all the code that was changed
recently I would only want to have another version of
PerContextProgram::getUniformLocation( int ) with string parameter so that
osgCall still compile.
Cheers,
Wojtek Lewandowski
