I am learning and building a native VR application for Oculus rift S, using PCSDK. I am using Vulkan as the graphics API and using OculusTinyRoomVk as the base example for my application. Till now I have been able to render vulkan models from a BREP file, but now I am stuck on how to display a pointer or a cursor to interact with my rendered objects. Can anyone guide my on how can I render or display a cursor or laser pointer and write functions to handle click events to interact with my objects? I am not using any game engine and trying to develop in a purely native way.
