Fields

shader_group_handle_size: u32

The size in bytes of the shader header.

max_ray_recursion_depth: u32

The maximum number of levels of ray recursion allowed in a trace command.

max_shader_group_stride: u32

The maximum stride in bytes allowed between shader groups in the shader binding table.

shader_group_base_alignment: u32

The required alignment in bytes for the base of the shader binding table.

shader_group_handle_capture_replay_size: u32

The number of bytes for the information required to do capture and replay for shader group handles.

max_ray_dispatch_invocation_count: u32

The maximum number of ray generation shader invocations which may be produced by a single vkCmdTraceRaysIndirectKHR or vkCmdTraceRaysKHR command.

shader_group_handle_alignment: u32

The required alignment in bytes for each shader binding table entry.

The value must be a power of two.

max_ray_hit_attribute_size: u32

The maximum size in bytes for a ray attribute structure.
