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 and Unity terrain details.
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.
---------------------------------
Features
---------------------------------
- Out of the box solution for complex GPU Instancing.
- VR compatible. Works with both single pass and multipass rendering modes.
- Easy to use interface.
- Tens of thousands of objects rendered lightning fast in a single draw call.
- GPU frustum culling.
- GPU occlusion culling (non-VR platforms only).
- Automatically configured custom shader support
- Complex hierarchies of prefabs instanced with a single click.
- Multiple sub-meshes support.
- LOD Groups support.
- Shadows casting and receiving support for instances (frustum culled instances still can cast shadows).
- Unity 5.6 support.
- Well documented API for procedural scenes and runtime modifications (examples included).
- Example scenes that showcase GPU Instancer capabilities.
- Map Magic integration.
Prefab Instancing Features:
- Ability to automatically instance prefabs at your scene that you distribute with your favorite prefab painting tool.
- Area localized rigidbody and physics support.
- Instance based material variations through API (similar to Material Property Blocks).
- Enabling and disabling instancing at runtime per instance basis.
- API to manage instanced prefabs at runtime.
Detail Instancing Features:
- Dense grass fields and vegetation with very high frame rates.
- Included vegetation shader with wind, shadows, AO, billboarding and various other properties.
- Support for custom shaders and materials.
- Cross quadding support: automatically turns grass textures to crossed quads.
- Ability to paint prefabs with custom materials on Unity terrain (with Unity terrain tools).
- Ability to use prefabs with LOD Groups on Unity terrain.
- Further performance improvements with automatic spatial partitioning.
- API to manage instanced terrain detail prototypes at runtime (examples included).
- Editor GPU Instancing simulation.
Planned Features:
- SpeedTree and Tree Creator support.
- Support for animation baking and skinned mesh renderers.
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)
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.

为了提供最快的性能，GPU Instancer使用Unity的DrawMeshInstancedIndirect方法和Compute Shaders来使用间接GPU实例化。
与静态批处理和网格合并相比，GPU实例化带来了巨大的性能提升。此外，其他可用的GPU实例化解决方案(包括Unity的材质选项和drawmeshinstancedmethod)在有限的缓冲区大小上失败，因此导致更多的绘制调用和更低的性能。通过使用间接方法，GPU Instancer旨在为这一问题提供最终解决方案，并在多次渲染相同网格时大幅提高性能。
