Following is sample code on how to create a stamp/logo in your View. This code has been tested in our sample hps_mfc_sandbox.
GetCanvas().GetWindowKey().GetTransparencyControl().SetDepthPeelingLayers(3);
HPS::SegmentKey mySegmentKey = GetCanvas().GetFrontView().GetAttachedModel().GetSegmentKey();
// Insert a cylinder in the main scene/view
HPS::CylinderKey cylinderKey = mySegmentKey.Subsegment("cylinder").InsertCylinder(Point(0.5f, 0.5f, 1), // first point
Point(-0.75f, -0.5f, -1), // second point
0.55f, // radius
HPS::Cylinder::Capping::Both); // capping enum
// Import visualize-logo.hsf to subwindow segment
// Note visualize-logo.hsf contain a transparent texture
HPS::SubwindowKit subwindowKit;
subwindowKit.SetSubwindow(HPS::Rectangle(0.7f, 1.0f, -1.0f, -0.7f), HPS::Subwindow::Type::Lightweight);
HPS::Stream::ImportNotifier importNotifier;
try {
HPS::Stream::ImportOptionsKit importOptionsKit;
importOptionsKit.SetSegment(mySegmentKey.Subsegment("subwindow")); // set destination segment
importNotifier = HPS::Stream::File::Import("C:/Users/simon.phung/Desktop/visualize-logo.hsf", importOptionsKit);
// the notifier can be used to check the load progress
float percent_complete;
importNotifier.Status(percent_complete);
// pauses this thread until the HSF is finished loading
importNotifier.Wait();
}
catch (HPS::IOException ioe) {
// handle exception
throw;
