%description
Space GL is a high-performance 3D multi-user client-server game engine.
It features real-time galaxy synchronization via shared memory (SHM),
advanced cryptographic communication frequencies (AES, PQC, etc.),
and a technical 3D visualizer based on OpenGL and FreeGLUT.

Documentation & System Architecture Evolution
## [v2.0.0] - Technical Optimization & Tactical Realism Update
### Summary
-This update marks a significant shift from the legacy architecture (documented in `README_old.md`) to a high-performance, mathematically rigorous framework. The primary focus is on Network Efficiency (v2.0), Dynamic Persistence, and Systemic Combat Physics.
---
### 1. Network & Infrastructure
-Differential Engine Integration: Migrated from a full-state update model to Delta Compression. The server now utilizes bitmasks to transmit only modified data blocks (Transform, Vitals, etc.).
-Bandwidth Optimization: Implementation of the new binary protocol has resulted in a 90-95% reduction in bandwidth consumption compared to the previous SDB/SHM model.
### 2. World Persistence & Dynamic Environment
-Dynamic Wreckage System: NPC destruction now triggers the real-time generation of permanent wrecks within the sector, supplementing existing static derelicts.
-Visual Fidelity: Integrated a dedicated "Dead Hull" shader for all post-combat wreckage to simulate "cold" and scorched materials, improving visual clarity and immersion.
### 3. Physics & Mathematical Balancing
-Quadratic Power Scaling: Navigation physics now follow , where Hyperdrive energy consumption scales quadratically with velocity.
-System Integrity: Added a "Penalties" layer where damaged subsystems directly impact energy efficiency and consumption rates.
-Precision Combat: Torpedo damage is no longer static; a 1.2x multiplier is now applied to direct precision hits.
### 4. Faction-Specific Mechanics & AI
-Material-Based Resistances: Introduced faction-specific hull properties:
-Swarm (Bio-armor): Native damage reduction.
-Gilded (Fragile): Increased damage vulnerability.
-Systemic AI Debuffs: Attacks targeting NPC engines now result in permanent maneuverability degradation during the encounter.
### 5. Developer Technical Deep-Dives
-Interest Management: Added documentation on quadrant-based spatial partitioning.
-Serialization: Detailed implementation guides for bitmask serialization.
-OpenGL State Management: New guidelines for shader state handling to eliminate visual interference between ship hulls and particle effects.
