Hi Robert,
I am not sure if i understood you properly . Did you mean to create the context
as follows :
Code:
class Context : public GraphicsOperation
{
public:
Context() : osg::GraphicsOperation("Context",false)
{
// initialize some of the opencl related member variables
}
virtual void operator() (osg::GraphicsContext *gc)
{
//in the argument we get the current and valid graphics context
//that i shall cast to the OS specific handle and then i shall
initialize all the
//opencl related variables here
}
//declare some opencl related variables here
}
Inside the main function i do the following as mentioned in osgvolume:
Code:
int main()
{
...........................
...........................
osg::ref_ptr<Context> context = new Context;
viewer.setRealizeOperation(context.get());
.................................
................................
}
Please let me know i got you right.
One more thing .... I want the Context class to be available to the rest of the
other files in the application . So i was thinking to declare the Context
object as follows instead :
Code:
//create a singleton opencl context to make sure that
//we are only working on one context
osgOpenCL::Singleton<osgOpenCL::Context>::init();
viewer.setRealizeOperation(osgOpenCL::Singleton<osgOpenCL::Context>::getPtr());
It will be nice to hear from you if there is better way to access Context class
variables.
I saw that GraphicsOperation constructor takes a boolean variable keep. All the
examples shows that the boolean variable is initialized to false. What is the
purpose of this variable ?
Thanks,
Sajjadul
