Syntax

typedef struct D3D12_HIT_GROUP_DESC {
  LPCWSTR              HitGroupExport;
  D3D12_HIT_GROUP_TYPE Type;
  LPCWSTR              AnyHitShaderImport;
  LPCWSTR              ClosestHitShaderImport;
  LPCWSTR              IntersectionShaderImport;
} D3D12_HIT_GROUP_DESC;

Members

HitGroupExport

The name of the hit group.

Type

A value from the D3D12_HIT_GROUP_TYPE enumeration specifying the type of the hit group.

AnyHitShaderImport

Optional name of the any-hit shader associated with the hit group. This field can be used with all hit group types.

ClosestHitShaderImport

Optional name of the closest-hit shader associated with the hit group. This field can be used with all hit group types.

IntersectionShaderImport

Optional name of the intersection shader associated with the hit group. This field can only be used with hit groups of type procedural primitive.
