Radiance Caching for Real-Time Volumetric Rendering

Mon, 01 Dec 2025 00:00:00 +0000

Researched and implemented a real-time radiance cache for volumetric path tracing using 3D Gaussian Splatting and a fused MLP as the cache representation.

Developed an online differentiable optimization pipeline in CUDA that adapts the Gaussian cache to dynamic lighting and transfer function changes during rendering.

Built a spatial-hash-based fused MLP for radiance caching on volumetric heterogeneous media. Supervised by Prof. Westermann.

GPU-Driven Point Cloud Renderer

Mon, 01 Jan 2024 00:00:00 +0000

Implemented a real-time GPU-driven renderer for large point clouds (140M+ points at ~100 FPS) using a custom 5-stage compute shader pipeline in Vulkan, based on Schütz et al. (2021, 2022).

Created a software rasterization pipeline using atomic uint64 depth-color packing and compute shaders, enabling fine-grained depth testing without a hardware depth buffer.

Implemented batch-based frustum culling, Morton-code spatial sorting, and screen-coverage LOD selection via 10-bit quantized position precision. Used Vulkan subgroup extensions for warp-level optimizations.

Evol Game Engine

Thu, 01 Jul 2021 00:00:00 +0000

Developed a high-performance, Vulkan-powered game engine with real-time physics simulation, applicable to vehicle simulation and digital twin technology.

Built a modular scene editor for real-time rendering and physics-based simulation.

Implemented the Vulkan renderer for the engine core and an OpenGL PBR renderer for the editor.

AUV Simulation & Interfacing

Fri, 01 Jan 2021 00:00:00 +0000

Full AUV physics simulation in Gazebo with ROS nodes using GStreamer to pipeline media from AUV/simulation to an external monitoring interface via a Qt application for the ground control team.

Designed the simulator, developed the Gazebo plugins and the C++ ROS nodes.

ImprovGFX

A renderer/rasterizer built from scratch to render .obj models and .tga textures, with OpenCL providing GPU acceleration.

Built a clean API for constructing scenes and shaders.

My name is Ahmed Alaa Ahmed Mohamed (aka Djoser / Djosen / Inedited). I'm a passionate creative software engineer and game developer.

I hold a master's degree in games engineering from TUM, with a strong background in graphics programming, real-time rendering, XR development, game development, and AI engineering.

I have experience working on AAA titles (Forza Motorsport 8) with Turn10 Games, as well as indie games and other personal projects. If it involves computers and is fun, I'm in.
