# D3D12_RAYTRACING_GEOMETRY_DESC (XBOX Series consoles)

> Describes a set of geometry that is used in the D3D12_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_INPUTS structure to provide input data to a raytracing.

Describes a set of geometry that is used in the [D3D12\_BUILD\_RAYTRACING\_ACCELERATION\_STRUCTURE\_INPUTS](/reference/graphics/d3d12/structs/d3d12_build_raytracing_acceleration_structure_inputs_public) structure to provide input data to a raytracing acceleration structure build operation.

## Syntax

```cpp theme={null}
typedef struct D3D12_RAYTRACING_GEOMETRY_DESC
{
    D3D12_RAYTRACING_GEOMETRY_TYPE Type;
    D3D12_RAYTRACING_GEOMETRY_FLAGS Flags;
    D3D12_RAYTRACING_GEOMETRY_TRIANGLES_DESC Triangles;
    D3D12_RAYTRACING_GEOMETRY_AABBS_DESC AABBs;
} D3D12_RAYTRACING_GEOMETRY_DESC
```

### Members

*Type*\
Type: D3D12\_RAYTRACING\_GEOMETRY\_TYPE

The type of geometry.

*Flags*\
Type: D3D12\_RAYTRACING\_GEOMETRY\_FLAGS

The geometry flags

*Triangles*\
Type: D3D12\_RAYTRACING\_GEOMETRY\_TRIANGLES\_DESC

A [D3D12\_RAYTRACING\_GEOMETRY\_TRIANGLES\_DESC](/reference/graphics/d3d12/structs/d3d12_raytracing_geometry_triangles_desc_public) describing triangle geometry, if <i>Type</i> is  [D3D12\_RAYTRACING\_GEOMETRY\_TYPE\_TRIANGLES](/reference/graphics/d3d12/enums/d3d12_raytracing_geometry_type_public).  Otherwise this parameter is unused.

*AABBs*\
Type: D3D12\_RAYTRACING\_GEOMETRY\_AABBS\_DESC

A [D3D12\_RAYTRACING\_GEOMETRY\_AABBS\_DESC](/reference/graphics/d3d12/structs/d3d12_raytracing_geometry_aabbs_desc_public) describing triangle geometry, if <i>Type</i> is  [D3D12\_RAYTRACING\_GEOMETRY\_TYPE\_PROCEDURAL\_PRIMITIVE\_AABBS](/reference/graphics/d3d12/enums/d3d12_raytracing_geometry_type_public).  Otherwise this parameter is unused.
