👋 Hi, I'm a 3D Graphics Engineer based in Japan with 6+ years of experience building high-performance visibility solutions for massive 3D environments - the kind that bring standard rendering pipelines to their knees. I specialize in occlusion culling, cell-based visibility computation, and GPU-accelerated rendering for large-scale scenes. I have deep expertise in C++, Vulkan, Embree, and modern graphics pipelines, with a proven track record of delivering production-ready culling systems for models with 1M+ polygons. My solutions achieve interactive frame rates on standard hardware while guaranteeing zero false negatives and minimal false positives - exactly what your project requires. Over the past years, I've built and delivered 15+ visibility solutions across BIM, digital twins, VR training, and simulation industries. I work with spatial data structures, ray casting, z-buffer algorithms, and hardware occlusion queries to ensure your 3D scenes render efficiently and accurately. 🔧 Here's How I Can Help You: ✅ Occlusion Culling & Visibility Systems 🔹 Implementing ray casting and z-buffer based occlusion tests 🔹 Building BVH, octree, and KD-tree spatial hierarchies 🔹 Leveraging Embree for high-performance ray tracing and occlusion queries 🔹 Integrating hardware occlusion queries (Vulkan queries) for GPU-accelerated culling 🔹 Designing conservative culling strategies with zero false negatives ✅ Cell-Based Visibility Computation 🔹 Partitioning large scenes into view-cells with portal connectivity graphs 🔹 Computing inter-cell visibility sets for conservative from-region visibility 🔹 Implementing cell-to-cell occlusion tests with surface occluder verification 🔹 Precomputing visibility sets for instant runtime lookup and minimal overhead 🔹 Optimizing cell granularity to balance memory usage and culling efficiency ✅ GPU Programming & Rendering Optimization 🔹 Vulkan pipeline development for high-performance rendering 🔹 Reducing draw calls and improving frame rates for large scenes 🔹 Implementing LOD generation and geometry instancing 🔹 Optimizing memory usage and rendering pipeline efficiency 🔹 Profiling and tuning for CPU and GPU performance ✅ Data Sanity & Validation Pipelines 🔹 Building automated validation checks for visibility set correctness 🔹 Implementing false-positive margin controls to limit rendering overhead 🔹 Creating comprehensive logging, monitoring, and debugging tools 🔹 Developing incremental update systems for dynamic scene changes 🔹 Ensuring data integrity with automated testing and validation pipelines 💼 Who I Work With: 🔹 Game Development Studios 🔹 AEC & Construction Companies 🔹 Digital Twin & BIM Platform Providers 🔹 VR/AR Training & Simulation Studios 🔹 Architecture & Engineering Firms 🔹 GIS & Urban Planning Organizations 💡 My Approach: I focus on building robust, production-ready visibility systems that handle massive datasets with precision and reliability. From spatial partitioning and PVS computation to GPU-accelerated occlusion queries and data validation - I deliver complete, well-documented solutions that work out of the box. 🛠️ My Tech Stack: 🔹 Languages: C++ (expert), Python, C# 🔹 Graphics APIs: Vulkan (expert), OpenGL, DirectX, WebGL 🔹 Ray Tracing: Embree (expert), OptiX 🔹 Spatial Data Structures: BVH, Octree, KD-Tree, Grid-based Partitioning 🔹 3D Formats: IFC, Revit, Rhino, 3ds Max, FBX, glTF, OBJ 🔹 Rendering Engines: Unity, Unreal Engine, Three.js 🔹 Tools: CMake, Git, Docker, CI/CD, Performance Profilers 📞 Let's connect! I'd love to discuss your specific requirements, data size, and performance goals - and show you how I can make your 3D scenes render in real-time.
