- cortex_demo.gif: 400px, 10fps, palette-optimized (833KB) - Converted from cortex.mp4 (3.8s, 1280x720, 30fps) - Shows physics simulation with PBR + shadows + multi-light - README.md: embedded GIF at top - .gitignore: added cortex.mp4 (source video, too large for git)
Cortex Engine
AI-Native 3D game engine with pure P/Invoke Vulkan 1.3 render backend.
Features
- Vulkan 1.3 — dynamic rendering, synchronization2, pure P/Invoke (no wrapper libraries)
- PBR Shading — Cook-Torrance BRDF, ACES tonemapping, multi-light support
- Cubemap Array Shadows — omnidirectional shadows from multiple point lights, 16-tap Poisson disk PCF
- Jolt Physics — rigid body dynamics, box/sphere colliders, gravity
- ImGui — debug overlay, light/shadow/physics controls
- AI/MCP — 7 tools (spawn, transform, material, delete, list, world state, screenshot) via HTTP/SSE
- Video Recording — FFmpeg pipe, 60 FPS capture, 30 FPS output
- ECS — Flecs.NET with Transform, Mesh, Material, Light, Camera, RigidBody components
- SDL3 Window — cross-platform, Vulkan surface
Quick Start
# Build
dotnet build CORTEX_ENGINE.sln -c Debug
# Run
./scripts/run.sh
# Run with AI/MCP server
./scripts/run.sh -- --mcp-port 5000
# Run tests
dotnet test tests/Engine.Tests/Engine.Tests.csproj -c Debug
Controls
- WASD — move camera
- Right-click + drag — look around
- Q/E — down/up
- Shift — speed boost
- ESC — quit
ImGui Panels
- Cortex Engine Debug — FPS, camera, entity count, physics toggle, reset scene
- Shadow & Light Parameters — per-light intensity/range/RGB, shadow bias/radius/farplane, ambient RGB
- Video Recording — start/stop recording to MP4
