C Specification

To query OpenGL ES API version requirements for an instance and system, call:

XrResult xrGetOpenGLESGraphicsRequirementsKHR(
    XrInstance                                  instance,
    XrSystemId                                  systemId,
    XrGraphicsRequirementsOpenGLESKHR*          graphicsRequirements);

Parameters

Parameter Descriptions

instance is an XrInstance handle previously created with xrCreateInstance.
systemId is an XrSystemId handle for the system which will be used to create a session.
graphicsRequirements is the XrGraphicsRequirementsOpenGLESKHR output structure.

The xrGetOpenGLESGraphicsRequirementsKHR function identifies to the application the minimum OpenGL ES version requirement and the highest known tested OpenGL ES version. xrGetOpenGLESGraphicsRequirementsKHR has to be called prior to calling xrCreateSession.

Valid Usage (Implicit)

The [XR_KHR_opengl_es_enable] extension must be enabled prior to calling xrGetOpenGLESGraphicsRequirementsKHR
instance must be a valid XrInstance handle
graphicsRequirements must be a pointer to an XrGraphicsRequirementsOpenGLESKHR structure
