◆ binding_offsets

const struct vkd3d_shader_descriptor_offset* vkd3d_shader_descriptor_offset_info::binding_offsets

Pointer to an array of struct vkd3d_shader_descriptor_offset objects. The 'static_offset' field contains an offset into the descriptor arrays referenced by the 'bindings' array in struct vkd3d_shader_interface_info. This allows mapping multiple shader resource arrays to a single binding point in the target environment.

'dynamic_offset_index' in struct vkd3d_shader_descriptor_offset allows offsets to be set at runtime. The 32-bit descriptor table push constant at this index will be added to 'static_offset' to calculate the final binding offset.

If runtime offsets are not required, set all 'dynamic_offset_index' values to ~0u and 'descriptor_table_count' to zero.

For example, to map Direct3D constant buffer registers 'cb0[0:3]' and 'cb1[6:7]' to descriptors 8-12 and 4-5 in the Vulkan descriptor array in descriptor set 3 and with binding 2, set the following values in the 'bindings' array in struct vkd3d_shader_interface_info:

type = VKD3D_SHADER_DESCRIPTOR_TYPE_CBV
register_space = 0
register_index = 0
binding.set = 3
binding.binding = 2
binding.count = 4
type = VKD3D_SHADER_DESCRIPTOR_TYPE_CBV
register_space = 0
register_index = 6
binding.set = 3
binding.binding = 2
binding.count = 2

and then pass {8, 4} as static binding offsets here.

This field may be NULL, in which case the corresponding offsets are specified to be 0.

◆ uav_counter_offsets

const struct vkd3d_shader_descriptor_offset* vkd3d_shader_descriptor_offset_info::uav_counter_offsets

Pointer to an array of offsets into the descriptor arrays referenced by the 'uav_counters' array in struct vkd3d_shader_interface_info. This works the same way as binding_offsets above.
