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 an UI on top of the already rendered 3D model. I tried integrating Dear Imgui, but now I am stuck on how to listen to click events to interact with Imgui. Can anyone give a suggestion on this? Is there any other way to do it rather than using Imgui?
