C Specification

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

// Provided by XR_KHR_opengl_enable
XrResult xrGetOpenGLGraphicsRequirementsKHR(
    XrInstance                                  instance,
    XrSystemId                                  systemId,
    XrGraphicsRequirementsOpenGLKHR*            graphicsRequirements);

Parameters

Parameter Descriptions

Description

The xrGetOpenGLGraphicsRequirementsKHR function identifies to the application the minimum OpenGL version requirement and the highest known tested OpenGL version. The runtime must return XR_ERROR_GRAPHICS_REQUIREMENTS_CALL_MISSING (XR_ERROR_VALIDATION_FAILURE may be returned due to legacy behavior) on calls to xrCreateSession if xrGetOpenGLGraphicsRequirementsKHR has not been called for the same instance and systemId.

Valid Usage (Implicit)
