Field Documentation

◆ act_attachments_by_key

struct u_hashmap_int* oxr_session::act_attachments_by_key

A map of action key to action attachment.

The action attachments are actually owned by the action set attachments, but we own the action set attachments, so this is OK.

If non-null, this means action sets have been attached to this session, since this map points to oxr_action_attachment members of oxr_session::act_set_attachments elements.

◆ act_set_attachments

struct oxr_action_set_attachment* oxr_session::act_set_attachments

An array of action set attachments that this session owns.

If non-null, this means action sets have been attached to this session.

Referenced by oxr_action_get_current_interaction_profile(), and oxr_action_sync_data().

◆ act_sets_attachments_by_key

struct u_hashmap_int* oxr_session::act_sets_attachments_by_key

A map of action set key to action set attachments.

If non-null, this means action sets have been attached to this session, since this map points to elements of oxr_session::act_set_attachments

◆ action_set_attachment_count

size_t oxr_session::action_set_attachment_count

Length of oxr_session::act_set_attachments.

◆ create_swapchain

XrResult(* oxr_session::create_swapchain) (struct oxr_logger *, struct oxr_session *sess, const XrSwapchainCreateInfo *, struct oxr_swapchain **)

To pipe swapchain creation to right code.

◆ frame_timing_spew

bool oxr_session::frame_timing_spew

Frame timing debug output.

Referenced by oxr_session_frame_end().

◆ frame_timing_wait_sleep_ms

uint32_t oxr_session::frame_timing_wait_sleep_ms

Extra sleep in wait frame.

◆ gfx_ext

enum oxr_session_graphics_ext oxr_session::gfx_ext

What graphics type was this session created with.

◆ handle

struct oxr_handle_base oxr_session::handle

Common structure for things referred to by OpenXR handles.

◆ has_ended_once

bool oxr_session::has_ended_once

There is a extra state between xrBeginSession has been called and the first xrEndFrame has been called.

These are to track this.

Referenced by oxr_session_request_exit().

◆ ipd_meters

float oxr_session::ipd_meters

IPD, to be expanded to a proper 3D relation.

◆ local_space_pure_relation

struct xrt_space_relation oxr_session::local_space_pure_relation

initial relation of head in "global" space.

Used as reference for local space.

◆ profiles_on_attachment_size

size_t oxr_session::profiles_on_attachment_size

Clone of all suggested binding profiles at the point of action set/session attachment.

oxr_session_attach_action_sets

Referenced by oxr_session_attach_action_sets().

◆ sleeper

struct os_precise_sleeper oxr_session::sleeper

Used to implement precise extra sleeping in wait frame.

◆ xcn

struct xrt_compositor_native* oxr_session::xcn

Native compositor that is wrapped by client compositors.

◆ xs

struct xrt_session* oxr_session::xs

The xrt_session backing this session.
