# fluidsD3D9 - Fluids (Direct3D Version)

## Description

An example of fluid simulation using CUDA and CUFFT, with Direct3D 9 rendering.  A Direct3D Capable device is required.

## Key Concepts

Graphics Interop, CUFFT Library, Physically-Based Simulation

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

## Prerequisites

Download and install the [CUDA Toolkit 12.0](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."
