Superminimal | basic WordPress demo theme to show Kirki Toolkit | Content Management System library

This is a question for anybody experienced with the Oculus Rift C++ SDK.

SDK Version: ovr_sdk_win_1.20.0_public

IDE: VS2013

I am trying to resolve a depth buffer problem in my code for a simplified 3D engine for the Oculus Rift DK2.

The OculusRoomTiny example supplied with the SDK is very complex as it is designed with versatility in mind. So, I've taken the SuperMinimal Sample code and used that as a basis for my engine. The SuperMinimal Sample did did not support multi-colour vertexes or depth buffers. So my code includes both.

I've had no problem creating depth buffers using Microsoft DirectX-11 libraries on PC apps so think it's an Oculus specific challenge. Note: the OculusRoomTiny example depth buffer works fine but is encapsulated in classes too complex for my code.

In my code, the Cube rendered as would be expected but inclusion of the Depth buffer only renders the world background colour.

I ripped the depth buffer code from the OculusRoomTiny_Advanced demo and am sure I have integrated it religiously. I've posted my code for comment. Please note, it is super minimal and does not clean up the COM objects.

Any advice would be welcome as I've been playing with the code now for 6 weeks!
