New format: WOC (Wowee Open Collision) — binary collision mesh for
custom zone walkability. Magic WOC1 (0x31434F57).
- WoweeCollisionBuilder::fromTerrain() generates collision triangles
from terrain heightmap with slope classification (50 deg threshold)
- Per-triangle flags: walkable (0x01), water (0x02), steep (0x04)
- Respects terrain holes (skips triangles in hole regions)
- Binary save/load with bounds, tile coords, triangle data
- Auto-exported on zone save alongside WOT/WHM/WOM/WOB
- Added to content pack validation (score now 0-7)
- FORMAT_SPEC.md v1.1 updated with WOC binary layout
- 19 new test assertions: flat terrain generation (32k tris all
walkable), save/load round-trip, hole skipping
- 328 total assertions across 84 test cases
- gitCommit() now uses double quotes for projectDir consistently with
gitPush/gitPull/gitStatus (was single quotes, breaking on paths with
apostrophes like "John's Project")
- Test suite auto-cleans test_output_formats/ directory via Catch2
event listener after all tests complete (was leaving empty dir)
Comprehensive test for WOT JSON metadata parsing: verifies tile coords,
texture list, chunk layers with holes, water data, doodad names and
placements (nameId, uniqueId, position, rotation, scale, flags), and
WMO names and placements (nameId, uniqueId, position, rotation, flags,
doodadSet) all survive the export→load cycle.
31 new assertions. Total: 309 assertions across 81 test cases.
All open format round-trips now have test coverage.
- WOM→M2 conversion now creates proper render batch (indexStart,
indexCount, vertexStart, vertexCount), texture references, material
with opaque blend mode — WOM models are now actually visible in the
client renderer instead of being invisible geometry-only shells
- 5 new JSON DBC test cases: basic load with strings/ints, float values,
empty records rejection, missing records key rejection, findRecordById
lookup across 3 records
- Total: 278 assertions across 80 test cases, all passing
- WOB save/load now serializes Material struct fields (flags, shader,
blendMode, texturePath) per group — was saving only texture paths
- FORMAT_SPEC.md v1.1: documents WOT doodad/WMO placements, WOB
material fields, doodad rotation, terrain stamps, WCP file list
- Test coverage: 5 new assertions verify material round-trip (flags,
shader, blendMode all preserved through save→load cycle)
- 260 total assertions across 75 test cases, all passing
- Remove the -0.15 vertical offset (kVOffset) from coordinate_projection,
coordinate_display, and zone_highlight_layer; continent UV math is now
identical to zone UV math
- Switch world_map_facade aspect ratio to MAP_W/MAP_H (1002×668) and crop
the FBO image with MAP_U_MAX/MAP_V_MAX instead of stretching the full
1024×768 FBO
- Account for ImGui title bar height (GetFrameHeight) in window sizing and
zone highlight screen-space rect coordinates
- Add ZMP 128×128 grid pixel-accurate hover detection in zone_highlight_layer;
falls back to AABB when ZMP data is unavailable
- Upgrade PlayerMarkerLayer with full Vulkan lifecycle (initialize,
clearTexture, destructor); loads MinimapArrow.blp and renders a rotated
32×32 textured quad via AddImageQuad; red triangle retained as fallback
- Expose arrowRotation_ / arrowDS_ accessors on Minimap; clean up arrow DS
and texture in Minimap::shutdown()
- Wire PlayerMarkerLayer::initialize() into WorldMapFacade::initialize()
- Update coordinate-projection test: continent and zone UV are now equal

Break the monolithic 1360-line world_map.cpp into 16 focused modules
under src/rendering/world_map/:
Architecture:
- world_map_facade: public API composing all components (PIMPL)
- world_map_types: Vulkan-free domain types (Zone, ViewLevel, etc.)
- data_repository: DBC zone loading, ZMP pixel map, POI/overlay storage
- coordinate_projection: UV projection, zone/continent lookups
- composite_renderer: Vulkan tile pipeline + off-screen compositing
- exploration_state: server mask + local exploration tracking
- view_state_machine: COSMIC→WORLD→CONTINENT→ZONE navigation
- input_handler: keyboard/mouse input → InputAction mapping
- overlay_renderer: layer-based ImGui overlay system (OCP)
- map_resolver: cross-map navigation (Outland, Northrend, etc.)
- zone_metadata: level ranges and faction data
Overlay layers (each an IOverlayLayer):
- player_marker, party_dot, taxi_node, poi_marker, quest_poi,
corpse_marker, zone_highlight, coordinate_display, subzone_tooltip
Fixes:
- Player marker no longer bleeds across continents (only shown when
player is in a zone belonging to the displayed continent)
- Zone hover uses DBC-projected AABB rectangles (restored from
original working behavior)
- Exploration overlay rendering for zone view subzones
Tests:
- 6 new test files covering coordinate projection, exploration state,
map resolver, view state machine, zone metadata, and integration

TransportManager decomposition:
- Extract TransportClockSync: server clock offset, yaw flip detection,
velocity bootstrap, client/server mode switching
- Extract TransportAnimator: spline evaluation, Z clamping, orientation
from server yaw or spline tangent
- Slim TransportManager to thin orchestrator delegating to ClockSync and
Animator; add pushTransform() helper to deduplicate WMO/M2 renderer calls
- Remove legacy orientationFromSplineTangent (now uses
CatmullRomSpline::orientationFromTangent)
Entity path following upgrade:
- Replace pathPoints_/pathSegDists_ linear lerp with
std::optional<CatmullRomSpline> activeSpline_
- startMoveAlongPath builds SplineKeys with distance-proportional timing
- updateMovement evaluates CatmullRomSpline for smooth Catmull-Rom
interpolation matching server-side creature movement
- Reset activeSpline_ on setPosition/startMoveTo to prevent stale state
Tests:
- Add test_transport_components (9 cases): ClockSync client/server/reverse
modes, yaw flip detection, Animator position eval, server yaw, Z clamping
- Link spline.cpp into test_entity for CatmullRomSpline dependency

Extract CatmullRomSpline (include/math/spline.hpp, src/math/spline.cpp) as a
standalone, immutable, thread-safe spline module with O(log n) binary segment
search and fused position+tangent evaluation — replacing the duplicated O(n)
evalTimedCatmullRom/orientationFromTangent pair in TransportManager.
Consolidate 7 copies of spline packet parsing into shared functions in
game/spline_packet.{hpp,cpp}: parseMonsterMoveSplineBody (WotLK/TBC),
parseMonsterMoveSplineBodyVanilla, parseClassicMoveUpdateSpline,
parseWotlkMoveUpdateSpline, and decodePackedDelta. Named SplineFlag constants
replace magic hex literals throughout.
Extract TransportPathRepository (game/transport_path_repository.{hpp,cpp}) from
TransportManager — owns path data, DBC loading, and path inference. Paths stored
as PathEntry wrapping CatmullRomSpline + metadata (zOnly, fromDBC, worldCoords).
TransportManager reduced from ~1200 to ~500 lines, focused on transport lifecycle
and server sync.

Implement GPU-driven Hierarchical-Z occlusion culling for M2 doodads
using a depth pyramid built from the previous frame's depth buffer.
The cull shader projects bounding spheres via prevViewProj (temporal
reprojection) and samples the HiZ pyramid to reject hidden objects
before the main render pass.
Key implementation details:
- Separate early compute submission (beginSingleTimeCommands + fence
wait) eliminates 2-frame visibility staleness
- Conservative safeguards prevent false culls: screen-edge guard,
full VP row-vector AABB projection (Cauchy-Schwarz), 50% sphere
inflation, depth bias, mip+1, min screen size threshold, camera
motion dampening (auto-disable on fast rotations), and per-instance
previouslyVisible flag tracking
- Graceful fallback to frustum-only culling if HiZ init fails
Fix dark WMO interiors by gating shadow map sampling on isInterior==0
in the WMO fragment shader. Interior groups (flag 0x2000) now rely
solely on pre-baked MOCV vertex-color lighting + MOHD ambient color.
Disable interiorDarken globally (was incorrectly darkening outdoor M2s
when camera was inside a WMO). Use isInsideInteriorWMO() instead of
isInsideWMO() for correct indoor detection.
New files:
- hiz_system.hpp/cpp: pyramid image management, compute pipeline,
descriptors, mip-chain build dispatch, resize handling
- hiz_build.comp.glsl: MAX-depth 2x2 reduction compute shader
- m2_cull_hiz.comp.glsl: frustum + HiZ occlusion cull compute shader
- test_indoor_shadows.cpp: 14 unit tests for shadow/interior contracts
Modified:
- CullUniformsGPU expanded 128->272 bytes (HiZ params, viewProj,
prevViewProj)
- Depth buffer images gain VK_IMAGE_USAGE_SAMPLED_BIT for HiZ reads
- wmo.frag.glsl: interior branch before unlit, shadow skip for 0x2000
- Render graph: hiz_build + compute_cull disabled (run in early compute)
- .gitignore: ignore compiled .spv binaries
- MEGA_BONE_MAX_INSTANCES: 2048 -> 4096
