- Delete 4 legacy GLSL 330 shaders (basic.vert/frag, terrain.vert/frag)
left over from OpenGL→Vulkan migration — Vulkan equivalents exist as
*.glsl files compiled to SPIR-V by the build system
- Delete orphaned mpq_manager.hpp/cpp (694 lines) — not in CMakeLists,
not included by any file, unreferenced StormLib integration attempt
- Add comments to water.frag.glsl wave constants explaining the
multi-octave noise design: non-axis-aligned directions prevent tiling,
frequency increases and amplitude decreases per octave for natural
water appearance
Squared distance optimizations across 30 files:
- Convert glm::length() comparisons to glm::dot() (no sqrt)
- Use glm::inversesqrt() for check-then-normalize patterns (1 rsqrt vs 2 sqrt)
- Defer sqrt to after early-out checks in collision/movement code
- Hottest paths: camera_controller (21), weather particles, WMO collision,
transport movement, creature interpolation, nameplate culling
Container and algorithm improvements:
- std::map<string> → std::unordered_map for asset/DBC/MPQ/warden caches
- std::mutex → std::shared_mutex for asset_manager and mpq_manager caches
- std::sort → std::partial_sort in lighting_manager (top-2 of N volumes)
- Double-lookup find()+operator[] → insert_or_assign in game_handler
- Add reserve() for per-frame vectors: weather, swim_effects, WMO/M2 collision
Threading and synchronization:
- Replace 1ms busy-wait polling with condition_variable in character_renderer
- Move timestamp capture before mutex in logger
- Use memory_order_acquire/release for normal map completion signaling
API additions:
- DBC getStringView()/getStringViewByOffset() for zero-copy string access
- Parse creature display IDs from SMSG_CREATURE_QUERY_SINGLE_RESPONSE
