🍃 What is Cullify?
Cullify is a client-side mod that culls decorative vegetation blocks (such as grass, flowers, ferns, algae, and kelp) based on distance from the player and customizable geometric shapes. By preventing distant or non-visible vegetation blocks from rendering, it reduces rendering load (vertex throughput and draw calls) without altering or removing the actual blocks in the world.

✨ Features
- ⚙️ Vegetation Culling — Reduces rendering load by hiding vegetation blocks that are beyond a configured distance.
- 📐 8 Geometric Culling Shapes — Customizable boundaries to control culling behavior around the player.
- 📉 LOD Density Filter — Deterministic, hash-based density filtering that thins out outer vegetation (75%, 50%, or 25%) to save CPU overhead near the boundary.
- 🌿 Double-Tall Vegetation Support — Synchronizes culling between the bottom and top halves of double-tall blocks (like sunflowers or tall grass) to prevent visual discrepancies.
- ⚙️ In-Game Config Menu — A configuration screen accessible via the
Kkeybind, chat commands, or the NeoForge mods menu. - 📊 Real-Time Statistics HUD — On-screen overlay tracking culled blocks, water replacements, chunk updates, and draw calls.
- 🧪 Native Sodium Compatibility — Direct hooks into Sodium's internal LevelSlice rendering pipeline and Sodium Options API.
📐 Geometric Culling Shapes
Unlike traditional culling mods, Cullify offers flexible mathematical boundary checks on both the horizontal plane (X/Z) and the vertical axis (Y):
| Icon | Shape | Geometry Mode | Description |
|---|---|---|---|
| 🟢 | Sphere | 3D Sphere | Culls blocks outside a 3D spherical radius. |
| 🌀 | Cylinder | Cylinder | Culls blocks outside a horizontal circular radius (infinite Y). |
| 📦 | Box | 3D Box | Culls blocks outside a 3D cubical bounding box. |
| 🔺 | Triangle | Triangle | Culls blocks outside an equilateral triangular boundary centered on the player. |
| ⬡ | Hexagon | Hexagon | Culls blocks outside a hexagonal boundary. |
| ⭐ | Star | Star | Culls blocks outside a 6-point star (union of two intersecting triangles). |
| ⏹️ | Square | Square | Culls blocks outside a flat square grid. |
| 🔵 | Circle | Circle | Culls blocks outside a flat horizontal circular boundary. |
