Detailed Description
Main compositor struct tying everything in the compositor together.
Field Documentation
◆ app_profiling
| struct { ... } comp_compositor::app_profiling |
Data exclusive to the begin_frame/end_frame for computing an estimate of the app's needs.
◆ base
| struct xrt_compositor_fd comp_compositor::base |
Referenced by xrt_gfx_provider_create_fd().
◆ client
| struct xrt_compositor* comp_compositor::client |
A link back to the compositor we are presenting to the client.
◆ compositor_frame_times
| struct { ... } comp_compositor::compositor_frame_times |
◆ current
| struct { ... } comp_compositor::current |
The current state we are tracking.
Settings is supposed to be read only.
◆ debug_var

◆ destroy_swapchains
| struct u_threading_stack comp_compositor::destroy_swapchains |
Thread object for safely destroying swapchain.
◆ expected_app_duration_ns
| int64_t comp_compositor::expected_app_duration_ns |
Estimated rendering time per frame of the application.
Set by the begin_frame/end_frame code.
- Todo:
- make this atomic.
