Regarding the OptiX Instancing example in the SDK, I want to do some modifications in the code for some test purposes. However, there are some issues with that.
1- Currently, the window remains open after the render. I want to close that after the display. So, I did the following change:
try {
/* Process command line args */
sutil::initGlut(&argc, argv);
vector<Material> materials;
vector<Geometry> geometries;
Context context = createContext();
createMaterials( context, materials );
createGeometries( context, geometries );
createNodeGraph( context, geometries, materials, no_accel );
context->validate();
context->launch( 0, width, height );
if( outfile.empty() ) {
sutil::displayBufferGlut( argv[0], context["output_buffer"]->getBuffer() );
} else {
sutil::displayBufferPPM( outfile.c_str(), context["output_buffer"]->getBuffer() );
}
context->destroy();
exit(0); ///////////// I ADDED THIS
} catch( Exception& e ) {
sutil::reportErrorMessage( e.getErrorString().c_str() );
exit( 1 );
}
After making that again, I still see the window remains open.

^C
As you can see, I have to press ^C.
How can I resolve that?
