Looking Glass Core SDK
The Looking Glass Core SDK is a cross-platform software development kit that makes your existing 3D software compatible with the Looking Glass. Use your application’s current UI and workflow to build seamless plug and play experiences for your end users.
Developers can use any rendering backend (DirectX, OpenGL, Metal, Vulkan) and any windowing library (e.g. GLFW, Qt, SDL). Beyond that, in order to render to the Looking Glass display, your application must be able to:
- Generate a borderless fullscreen window at a specific position
- Distort the camera's projection matrix
- Render multiple views to a texture
- Apply a shader to the texture
The Looking Glass Core SDK provides your application all the information it needs to draw to the Looking Glass, including window information and calibration.
Why Window Information is Important
Operating systems see connected Looking Glass devices as HDMI monitors. Your application must know how the OS sees the monitor so that it knows where to draw the windows.
Why Calibration Data is Important
Each Looking Glass has its own device-specific calibration, read over USB. Your application must know this calibration data in order to render holograms properly on the Looking Glass.
Looking Glass Core (the graphics library integrated into your application) gets this information by providing an API endpoint to request information from Looking Glass Bridge (a persistent driver-like service that is installed on the user’s machine). Looking Glass Core uses this information to draw your 3D scene to the Looking Glass.
These reference documents cover some of the underlying logic inside the SDK:
An example OpenGL project is distributed as part of the Looking Glass Core SDK to demonstrate how to move the camera and render to a texture in the appropriate format.
