Detailed Description
All the pure data values associated with a composition layer.
The xrt_swapchain references and xrt_device are provided outside of this struct.
Field Documentation
◆
| union { ... } xrt_layer_data::@217 |
Union of data values for the various layer types.
The initialized member of this union should match the value of xrt_layer_data::type. It also should be clear because of the layer function called between xrt_compositor::layer_begin and xrt_compositor::layer_commit where this data was passed.
◆ advanced_blend
| struct xrt_layer_advanced_blend_data xrt_layer_data::advanced_blend |
Advanced blend factors.
◆ color_bias
| struct xrt_colour_rgba_f32 xrt_layer_data::color_bias |
Modulate the color sourced from the images.
◆ color_scale
| struct xrt_colour_rgba_f32 xrt_layer_data::color_scale |
Modulate the color sourced from the images.
◆ depth_test
| struct xrt_layer_depth_test_data xrt_layer_data::depth_test |
Depth test data.
◆ flags
| enum xrt_layer_composition_flags xrt_layer_data::flags |
Composition flags.
◆ flip_y
| bool xrt_layer_data::flip_y |
Whether the main compositor should flip the direction of y when rendering.
This is actually an input only to the "main" compositor comp_compositor. It is overwritten by the various client implementations of the xrt_compositor interface depending on the conventions of the associated graphics API. Other xrt_compositor_native implementations that are not the main compositor just pass this field along unchanged to the "real" compositor.
◆ name
| enum xrt_input_name xrt_layer_data::name |
Often XRT_INPUT_GENERIC_HEAD_POSE.

◆ timestamp
| int64_t xrt_layer_data::timestamp |
"Display no-earlier-than" timestamp for this layer.
The layer may be displayed after this point, but must never be displayed before.
◆ type
| enum xrt_layer_type xrt_layer_data::type |
Tag for compositor layer type.
Referenced by comp_layer_accum::comp_layer_accum_get_depth_swapchain(), comp_layer::comp_layer_get_depth_swapchain(), comp_render_gfx_dispatch(), and sdl_program_plus_render().
