Fields§
§max_geometry_count: u64
The maximum number of geometries in a bottom level acceleration structure.
max_instance_count: u64
The maximum number of instances in a top level acceleration structure.
max_primitive_count: u64
The maximum number of triangles or AABBs in all geometries in a bottom level acceleration structure.
max_per_stage_descriptor_accel_structs: u32
The maximum number of acceleration structure bindings that can be accessible to a single shader stage in a pipeline layout.
Descriptor bindings with a descriptor type of
VK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR
count against this limit.
max_descriptor_set_accel_structs: u32
The maximum number of acceleration structure descriptors that can be included in descriptor bindings in a pipeline layout across all pipeline shader stages and descriptor set numbers.
Descriptor bindings with a descriptor type of
VK_DESCRIPTOR_TYPE_ACCELERATION_STRUCTURE_KHR
count against this limit.
min_accel_struct_scratch_offset_alignment: u32
The minimum required alignment, in bytes, for scratch data passed in to an acceleration structure build command.
