# D3D12_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_TOOLS_VISUALIZATION_HEADER (XBOX Series consoles)

> Describes the GPU memory layout of an acceleration structure visualization.

Describes the GPU memory layout of an acceleration structure visualization.

## Syntax

```cpp theme={null}
typedef struct D3D12_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_TOOLS_VISUALIZATION_HEADER
{
    D3D12_RAYTRACING_ACCELERATION_STRUCTURE_TYPE Type;
    UINT NumDescs;
} D3D12_BUILD_RAYTRACING_ACCELERATION_STRUCTURE_TOOLS_VISUALIZATION_HEADER
```

### Members

*Type*\
Type: D3D12\_RAYTRACING\_ACCELERATION\_STRUCTURE\_TYPE

The type of acceleration structure.

*NumDescs*\
Type: UINT

The number of descriptions.

## Remarks

This structure functions like the inverse of the inputs to an acceleration structure build, focused on the instance or geometry details, depending on the acceleration structure type.

## Requirements

**Header:** d3d12\_xs.h\
**Library:** d3d12\_xs.lib\
**Supported Platforms**: XBOX Series consoles
