Hologram Scanner & 3D Radar Suite
AAA In-World Holographic Radars, LiDAR Scanners & Vehicle Holo-Twins for Unreal Engine 5.
Built for sci-fi cockpits, mech combat, space simulators, and open-world games.

🌟 Overview
Tired of flat 2D minimaps that break immersion? Hologram Scanner & 3D Radar Suite creates real 3D holograms right inside your game world. Place them inside vehicle cockpits, wear them on a character's wrist, project them onto command tables, or scan entire landscapes with an expanding pulse wave.
100% Plug & Play: Drag and drop any of the included Blueprints into your level or character—it works immediately with zero code or complex setup.

⚡ Performance & Low-Overhead Architecture
Built in native C++ for high-performance projects where every millisecond counts:
• Sub-Millisecond CPU Time: Efficient C++ ray traces and sweep math minimize game-thread execution (< 0.1ms in tests).
• Zero GC Hitching: Pre-allocated circular ring buffers ensure 0 new memory allocations per frame, eliminating micro-stutters.
• 1 Draw Call GPU Instancing: Thousands of holographic dots render in a single GPU pass.
• GPU-Driven Dot Decay: Dot lifetimes and smooth fading are calculated on the GPU in the material, leaving your CPU free.
• 80% CPU Savings on Vehicle Twins: Replaces heavy Animation Blueprints with direct bone sampling, forced low LODs, and a sci-fi low FPS rate.
• VR, PC & Console Ready: Ultra-lightweight footprint leaves maximum headroom for VR headsets and demanding scenes.

🎮 Three Complete Gameplay Systems
1. 📡 Volumetric 3D Holographic Radar (ARadarHologram)
• Real 3D Scanning: Scans floors, walls, ceilings, and obstacles into a miniature 3D hologram.
• Full Room Coverage: Equal-Distance mode spaces dots evenly across floors, roofs, walls, and flying drones.
• Sci-Fi Micro-Cube Voxels: Sharp digital cube blips eliminate visual blur and overlap.
• Sweep Beam & Audio: 360° sweeping beam flashes red on enemy contact with procedural MetaSound audio pings.
• Target Tracking & IFF: Distinguishes terrain from enemies and hovers 3D distance tags above targets.
2. 🌐 1:1 Ground Pulse Terrain Scanner (AHologramPulseScanner)
• Expanding Wavefront: Sends an impulse wave across the ground up to 50m+ in an organic honeycomb pattern.
• Live Slope Colors: Evaluates ground steepness in real time to guide player traversal:
- 🟢 Safe Ground (< 25°): Neon Cyan (Easy walking)
- 🟡 Caution Slope (25°–45°): Amber (Steep climb)
- 🔴 Hazard Wall (≥ 45°): Danger Red (Sheer cliff/wall)
• Zero-Clipping Placement: Markers lift above ground polygons so they never sink into terrain or flicker.
• Enemy Tagging: Highlights hidden enemies behind cover with 3D markers and distance tags.
3. 🤖 Vehicle & Mech Hologram Twin (UVehicleHologramComponent)
• Live Animated Hologram: 3D mini-hologram mirroring steering wheels, mech legs, or ship thrusters in sync with the real vehicle.
• Authentic Sci-Fi Stutter: Updates at low FPS for a classic holographic look while saving CPU cycles.
• Rotating Display: Optional turntable spin for menu screens or cockpit displays.
