# simpleD3D12 - Simple D3D12 CUDA Interop

## Description

A program which demonstrates Direct3D12 interoperability with CUDA.  The program creates a sinewave in DX12 vertex buffer which is created using CUDA kernels. DX12 and CUDA synchronizes using DirectX12 Fences. Direct3D then renders the results on the screen.  A DirectX12 Capable NVIDIA GPU is required on Windows10 or higher OS.

## Key Concepts

## Dependencies needed to build/run
[DirectX12](../../README.md#directx12)

## Prerequisites

Download and install the [CUDA Toolkit 10.2](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."
