Hello peoples,
anyone know how to get the displayed frame rate to be an average over some set time in make_scene? Or perhaps a function I can make that is called every frame so I can do it myself? As the framerate gets higher it gets more spastic. Carson

In class FooClass, do this:
#include <Interface/MantaInterface.h>
#include <SCIRun/Core/Thread/Time.h>

then call this once (probably put it in your constructor or preprocess function):
 context.manta_interface->registerSerialPreRenderCallback(
   Callback::create(this, &FooClass::YourFunctionName));

Then in your class do:
void FooClass::YourFunctionName(int proc, int numProcs)
{
//insert time code to measure fps.
}


YourFunctionName will then get called once per frame. In there you can add some timing code (look in Time.h for how to do it).
