GPU Instancer is an out of the box solution to display extreme numbers of objects on screen with high performance. With a few mouse clicks, you can instance your prefabs, Unity Terrain details and trees.

GPU Instancer provides user friendly tools to allow everyone to use Indirect GPU Instancing without having to go through the deep learning curve of Compute Shaders and GPU infrastructure. Also, an API with extensive documentation is provided to manage runtime changes.

Requirements:
- DirectX 11 or DirectX 12 and Shader Model 5.0 GPU (Windows, Windows Store)
- Metal (macOS, iOS)
- OpenGL Core 4.3 (Windows, Linux)
- Vulkan (Android, Windows, Linux)
- OpenGL ES 3.1 (Android 8.0 Oreo or later)
- Modern Consoles (PS4, Xbox One)

Please also note that even though some integrated graphics cards may satisfy these requirements, they may not provide the boost you can get from GPU Instancing. Therefore, hardware with a dedicated GPU is recommended.

To provide the fastest possible performance, GPU Instancer utilizes Indirect GPU Instancing using Unity's DrawMeshInstancedIndirect method and Compute Shaders.

GPU Instancing results in magnitudes of performance improvement over static batching and mesh combining. Also, other available solutions for GPU Instancing (including Unity's material option and the DrawMeshInstanced method) fail short on limited buffer sizes and therefore result in more draw calls and less performance. By using the indirect method GPU Instancer aims to provide the ultimate solution for this, and increases performance considerably while rendering the same mesh multiple times.

GPU Instancer是一个开箱即用的解决方案，以显示极端数量的对象在屏幕上高性能。通过几次鼠标点击，你可以实例化你的预置，统一地形细节和树木。

GPU Instancer提供了用户友好的工具，允许每个人使用间接的GPU实例化，而不必经过计算着色器和GPU基础设施的深度学习曲线。此外，还提供了一个带有大量文档的API来管理运行时更改。

也请注意，即使一些集成显卡可能满足这些要求，他们可能不会提供你可以从GPU实例化得到的提升。因此，推荐使用专用GPU的硬件。

为了提供尽可能快的性能，GPU Instancer使用Unity的DrawMeshInstancedIndirect方法和Compute Shaders来间接地使用GPU实例化。

GPU实例化的结果在静态批处理和网格结合的性能改善的幅度。另外，其他可用的GPU实例化解决方案(包括Unity的material选项和drawmeshinstancemethod)在有限的缓冲区大小上也会失败，从而导致更多的draw调用和更低的性能。GPU Instancer通过采用间接的方法为这一问题提供了最终的解决方案，并在多次渲染相同网格的同时显著提高了性能。
