🍃 What is Cullify?

Cullify is an advanced, ultra-optimized, client-side culling system for Minecraft. It drastically improves your rendering performance by intelligently and dynamically culling decorative vegetation (grass, flowers, ferns, algae, kelp, etc.) based on your distance and customizable geometric shapes — without ever altering or removing the actual blocks in the world.

✨ Features

🚀 Massive FPS Boost: Substantially reduces vertex throughput and draw calls by culling non-visible or distant vegetation.
🟩 8 Geometric Culling Shapes: Fully customizable boundaries to control culling behavior exactly how you want 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: Perfectly synchronizes culling between the bottom and top halves of double-tall blocks (like sunflowers or tall grass) to prevent any visual glitching.
⚙️ In-Game Config Menu: Fully custom configuration screen accessible via the K keybind, 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.

🎮 Controls & Commands

Configuring and inspecting Cullify in-game is effortless:

⌨️ Keybinds

K — Opens the custom Cullify GUI Config Screen.

💬 Chat Commands

/cullify menu — Opens the configuration GUI menu.
/cullify debug — Toggles the real-time statistics HUD overlay.
/cullify stats — Prints current performance statistics directly into the chat.
/cullify verbose — Toggles verbose logging for debugging.
/cullify reload — Forces a complete reload of the client level renderer chunks.

🔌 Compatibility & Requirements

Sodium / Embeddium: Fully integrated. Hooks directly into Sodium's internal LevelSlice rendering pipeline to batch-cull blocks in MDI (Multi-Draw Indirect) buffers. The Culling Shape options and configurations are also registered directly inside Sodium's Video Settings menu!
Vanilla Renderer: Fallback compatibility included for the standard Minecraft block rendering pipeline.
🔒 100% Client-Side: This mod runs entirely on your client. You can join any server (Vanilla, Spigot, Forge, Paper, etc.) without any issues!
