示例1: run
/**
Run the dynamics for a cycle.
*/
void run( Real dt ) {
// fetch the command in the buffer
//get_command();
#ifdef USE_OSG
if (ONSCREEN_RENDER)
{
if (viewer.done())
return;
viewer.frame();
}
#endif
// Note: research how the original driver sets up all the parameters that
// drive step size. sim->step(dt) is not sufficient in and of itself so
// there must be another or more parameters that manipulate this state info
//sim->step( dt );
// step the sim forward
STEP_SIZE = dt;
step((void*) &sim);
// publish any state change
//publish_state();
//#ifdef USE_OSG
//usleep(DYNAMICS_FREQ);
//#endif
}示例2: main
int main(int argc, char** argv)
{
viewer.setSceneData(root.get());

root->addChild(startMenu->_camera);
if(root.valid())

viewer.realize();
while(!viewer.done())
{
viewer.frame();
//update();
}
}

}示例3: step
// Step the dynamics forward
