## 🧾 Summary

A Unity package inspired by Virtual Geometry, enabling massive, detailed asset rendering with seamless LOD management and virtualized geometry. It is a fully GPU-driven solution.

Seamless Virtual Geometry is a package similar to Unreal's Virtual Geometry. This package allows developers to render massive amounts of detailed assets with unparalleled efficiency, leveraging advanced level-of-detail (LOD) management. Some source code is provided, while the core code and shaders are provided in the form of DLLs and Asset Bundles.

## ⚙️ Description

### ✅ Supported Features:

- Meshlet LOD and BVH node generation  
- Meshlet LOD hierarchy  
- BVH tree  
- Instance GPU frustum and occlusion culling  
- BVH node GPU frustum and occlusion culling with LOD traversal  
- Meshlet GPU frustum and occlusion culling  
- Hardware rasterizer  
- Visibility buffer  
- Shadow support, including point light shadows and directional light shadows (CSM)  
- Deferred material  
- Per-chunk material culling  
- Single-phase Occlusion Culling  
- Programmable rasterizer (Alpha Test)  
- Skinned mesh  
- Rendering layer supported  
- Deferred shading only  
- Per-object GI is supported (per-object light probe, reflection probe and Lightmap)  
- Meshlet generation speed up  

### ❌ Not Supported Yet:

- No software rasterizer  
- No two phase Occlusion Culling  
- No Streaming  
- No Compression currently  
- Not Support Unity Terrain (no plan to support)
