# simpleD3D11 - Simple D3D11

## Description

Simple program which demonstrates  how to use the CUDA D3D11 External Resource Interoperability APIs to update D3D11 buffers from CUDA and synchronize between D3D11 and CUDA with Keyed Mutexes.

## Key Concepts

Graphics Interop, Image Processing

## Dependencies needed to build/run
[DirectX](../../../README.md#directx)

## Prerequisites

Download and install the [CUDA Toolkit 12.5](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
Make sure the dependencies mentioned in [Dependencies]() section above are installed.

## Build and Run

### Windows
The Windows samples are built using the Visual Studio IDE. Solution files (.sln) are provided for each supported version of Visual Studio, using the format:
```
*_vs<version>.sln - for Visual Studio <version>
```
Each individual sample has its own set of solution files in its directory:

To build/examine all the samples at once, the complete solution files should be used. To build/examine a single sample, the individual sample solution files should be used.
> **Note:** Some samples require that the Microsoft DirectX SDK (June 2010 or newer) be installed and that the VC++ directory paths are properly set up (**Tools > Options...**). Check DirectX Dependencies section for details."
