Detailed Description

UBO data that is sent to the compute layer shaders.

Field Documentation

_padding0

uint32_t render_compute_layer_ubo_data::_padding0

Todo:

Implement separated samplers and images (and change to samplers[2])

color_scale

struct xrt_colour_rgba_f32 render_compute_layer_ubo_data::color_scale

Color scale and bias for all layers.

struct { ... } render_compute_layer_ubo_data::cylinder_data

For cylinder layer.

struct { ... } render_compute_layer_ubo_data::eq2_data

For equirect2 layers.

struct { ... } render_compute_layer_ubo_data::image_info

Which image/sampler(s) correspond to each layer.

std140 uvec2, because it is an array it gets padded to vec4.

struct { ... } render_compute_layer_ubo_data::layer_data

Corresponds to enum xrt_layer_type and unpremultiplied alpha.

std140 uvec2, because it is an array it gets padded to vec4.

mv_inverse

struct xrt_matrix_4x4 render_compute_layer_ubo_data::mv_inverse

Shared between cylinder and equirect2.

struct { ... } render_compute_layer_ubo_data::quad_extent

Quad extent in world scale.

struct { ... } render_compute_layer_ubo_data::quad_position

For quad layers.

All quad transforms and coordinates are in view space

transforms_timewarp

struct xrt_matrix_4x4 render_compute_layer_ubo_data::transforms_timewarp

For projection layers.

Timewarp matrices
