%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.

* Thu Mar 5 2026 Nicola Taibi <nicola.taibi.1967@gmail.com> - 2026.02.09-%{rel}
1. HUD Data Correction (spacegl_3dview)
  We identified and resolved a data swap in the textual HUD. Previously, the values for the Left (L) and Right (RI) shields were inverted. I swapped the internal indices so that Index 5 now correctly represents the Left sector and Index 4 represents the Right sector, ensuring the telemetry matches the ship's physical state.


2. Shield Pitch Alignment (The "Mark" Issue)
   We fixed the visual positioning of the shield sectors during vertical maneuvers:
   * The Problem: While the ship tilted up or down (Mark/Pitch), the shield sectors remained static or rotated on the wrong       axis, causing a visual detachment from the hull.
   * The Solution: I updated the transformation logic in drawShieldEffect to calculate a dynamic pitch axis based on the ship's current heading. 
   * Final Refinement: To ensure perfect accuracy in spacegl_3dview, I synchronized its rotation sequence with the ship's actual 3D model transformation (Heading - 90° followed by Mark).
