C Specification

The XrGraphicsBindingOpenGLXcbKHR structure is defined as:

typedef struct XrGraphicsBindingOpenGLXcbKHR {
    XrStructureType             type;
    const void* XR_MAY_ALIAS    next;
    xcb_connection_t*           connection;
    uint32_t                    screen_number;
    xcb_glx_fbconfig_t          fbconfigid;
    xcb_visualid_t              visualid;
    xcb_glx_drawable_t          glxDrawable;
    xcb_glx_context_t           glxContext;
} XrGraphicsBindingOpenGLXcbKHR;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to an extension-specific structure.

  • connection is a valid xcb_connection_t.

  • screen_number is an index indicating which screen should be used for rendering.

  • fbconfigid is a valid XCB OpenGL GLX xcb_glx_fbconfig_t.

  • visualid is a valid XCB OpenGL GLX xcb_visualid_t.

  • glxDrawable is a valid XCB OpenGL GLX xcb_glx_drawable_t.

  • glxContext is a valid XCB OpenGL GLX xcb_glx_context_t.

Description

When creating an OpenGL-backed XrSession on any Linux/Unix platform that utilizes X11 and GLX, via the Xlib library, the application will provide a pointer to an XrGraphicsBindingOpenGLXcbKHR in the next chain of the XrSessionCreateInfo.

The required window system configuration define to expose this structure type is XR_USE_PLATFORM_XCB.

Valid Usage (Implicit)

  • The [XR_KHR_opengl_enable] extension must be enabled prior to using XrGraphicsBindingOpenGLXcbKHR

  • type must be XR_TYPE_GRAPHICS_BINDING_OPENGL_XCB_KHR

  • next must be NULL

  • connection must be a pointer to an xcb_connection_t value

  • screen_number must be a valid uint32_t value

  • fbconfigid must be a valid xcb_glx_fbconfig_t value

  • visualid must be a valid xcb_visualid_t value

  • glxDrawable must be a valid xcb_glx_drawable_t value

  • glxContext must be a valid xcb_glx_context_t value
