Detailed Description

UBO data that is sent to the compute layer shaders.

Field Documentation

struct { ... } render_compute_layer_ubo_data::cylinder_data[ (XRT_MAX_LAYERS) ]

For cylinder layer.

struct { ... } render_compute_layer_ubo_data::eq2_data[ (XRT_MAX_LAYERS) ]

For equirect2 layers.

struct { ... } render_compute_layer_ubo_data::images_samplers[ (XRT_MAX_LAYERS) ]

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

struct { ... } render_compute_layer_ubo_data::layer_type[ (XRT_MAX_LAYERS) ]

std140 uvec2, corresponds to enum xrt_layer_type and unpremultiplied alpha.

mv_inverse

struct xrt_matrix_4x4 render_compute_layer_ubo_data::mv_inverse[(XRT_MAX_LAYERS)]

Shared between cylinder and equirect2.

padding

uint32_t render_compute_layer_ubo_data::padding[XRT_MAX_VIEWS]

Todo:

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

struct { ... } render_compute_layer_ubo_data::quad_extent[ (XRT_MAX_LAYERS) ]

Quad extent in world scale.

struct { ... } render_compute_layer_ubo_data::quad_position[ (XRT_MAX_LAYERS) ]

For quad layers.

All quad transforms and coordinates are in view space

transforms

struct xrt_matrix_4x4 render_compute_layer_ubo_data::transforms[(XRT_MAX_LAYERS)]

For projection layers.

Timewarp matrices
