GPU Instancer是一款GPU显示的解决方案，可在屏幕上显示极高数量的对象，并且性能卓越，支持Unity 5.6.5以上版本。
GPU Instancer提供用户友好的工具，允许每个人都可以使用间接GPU实例化，而无需通过计算着色器和GPU基础架构的深度学习曲线。此外，还提供了一个包含大量文档的API来管理运行时更改。
GPU Instancer特征：
– 复杂GPU实例解决方案。
– VR兼容，适用于单通道和多通道渲染模式。
– 易于使用的界面。
– 数以万计的物体在一次平局中闪电般闪过。
– GPU截锥体扑杀。
– 自动配置自定义着色器支持
– 通过一次单击实现的复合预制件层次结构。
– 支持多个子网格。
– LOD组支持。
– 阴影投射和接受实例支持（截锥取材的实例仍然可以投射阴影）。
– Unity 5.6支持。
– 程序场景和运行时修改的良好文档化API（包含示例）。
– 展示GPU Instancer功能的示例场景。
