UnityTextureReaderD3D is a plugin package for Unity that enables easy access to pixel data from Direct3D11 and Direct3D12 textures. The package includes native plugins for both APIs, providing efficient texture reading without the need for additional scripts or workarounds.

• Supports Direct3D11 and Direct3D12 textures.
• Efficient and easy-to-use native plugins.
• Compatible with Unity game engine.

• Unity game engine (compatible with Direct3D11 and Direct3D12)

You can install the UnityTextureReaderD3D package using the Unity Package Manager:

1. Open your Unity project.
2. Go to Window > Package Manager.
3. Click the "+" button in the top left corner, and choose "Add package from git URL..."
4. Enter the GitHub repository URL: https://github.com/cj-mills/UnityTextureReaderD3D.git
5. Click "Add". The package will be added to your project.

For Unity versions older than 2021.1, add the Git URL to the manifest.json file in your project's Packages folder as a dependency:

{
  "dependencies": {
    "com.cj-mills.unitytexturereaderd3d": "https://github.com/cj-mills/UnityTextureReaderD3D.git",
    // other dependencies...
  }
}

The UnityTextureReaderD3D package provides two native plugins: UnityTextureReaderD3D11 and UnityTextureReaderD3D12, and C# scripts to interact with the plugin functions. The appropriate script will be automatically chosen based on your Unity project's rendering pipeline.

Here's an example of how to use the package:

using System;
using UnityEngine;
using UnityEngine.Rendering;
using CJM.UnityTextureReaderD3D;

public class TextureReaderExample : MonoBehaviour
{
    private ITexturePixelDataReaderD3D _texturePixelDataReaderD3D;

    private void Start()
    {
        if (SystemInfo.graphicsDeviceType == GraphicsDeviceType.Direct3D11)
        {
            _texturePixelDataReaderD3D = new Direct3D11TexturePixelDataReader();
        }
        else if (SystemInfo.graphicsDeviceType == GraphicsDeviceType.Direct3D12)
        {
            _texturePixelDataReaderD3D = new Direct3D12TexturePixelDataReader();
        }
    }

    private void ReadPixels(Texture2D texture)
    {
        IntPtr pixelDataPtr = _texturePixelDataReaderD3D.GetPixelDataFromTexture(texture.GetNativeTexturePtr());

        if (pixelDataPtr != IntPtr.Zero)
        {
            // Process pixel data...

            _texturePixelDataReaderD3D.FreePixelData(pixelDataPtr);
        }
    }
}

A demo project called UnityTextureReaderD3D_Demo is available to help you get started with using the UnityTextureReaderD3D package. The demo project demonstrates how to access and read pixel data from Direct3D11 and Direct3D12 textures in Unity. To get started, simply clone the demo project, open it in Unity, and follow the instructions provided in the demo project's README.
