D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE enumeration (d3d12.h)

  • Article

Specifies the type of a raytracing acceleration structure.

Syntax

typedef enum D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE {
  D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL = 0,
  D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL = 0x1
} ;

Constants

 
D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE_TOP_LEVEL
Value: 0
Top-level acceleration structure.
D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE_BOTTOM_LEVEL
Value: 0x1
Bottom-level acceleration structure.

Remarks

Bottom-level acceleration structures each consist of a set of geometries that are building blocks for a scene. A top-level acceleration structure represents a set of instances of bottom-level acceleration structures.
