Hi, I am Rareș

I am a Graphics Programmer
I love voxels
I love global illumination

Rareș Dumitru

Student at Breda University of Applied Sciences

I am Rareș, a self-motivated student passionate about game development with a drive towards research. Voxel engines and everything regarding real-time global illumination are my favorite topics to study and work with. Feel free to reach out to me with any questions about my work or just chit-chat about voxels or graphics.

Projects

Cone tracing cellular automata GI

Stretch goal explored by me during the OpenGL voxel team project. I presented the explored technique at GPC 2024 with a small talk. Cellular automata is used for direct light propagation and cone tracing for indirect calculation and direct sampling. Volumetric and specular reflections are done also with cone tracing.

rVox

Custom voxel engine project made during Block B in Year 2 at BUAS. The engine is made in C++ and OpenGL with OpenCL for the rendering/compute pipeline. Lighting is being calculated per voxel using software ray tracing inside a OpenCL kernel.

Wexel engine

Custom voxel engine made as a self study project with a friend in 32 hours of tracked work. Made in WebGPU and javascript+HTML, rendering a chunk of 128x128x128 voxels inside a rasterized box, fully ray traced shadows and rendering with basic PBR support.

2D CPU Ray Tracer

This 2D Ray Tracer was developed as a course project at BUAS during Block C of Year 1. The entire rendering pipeline runs on the CPU in C++. To demonstrate the dynamic lighting capabilities, I made a small snake spinoff on top of the engine. Goals and Motivations Technical Goals: Explore fundamental ray-tracing concepts such as intersection checks, shadows, lighting. Gain experience on CPU based renderers while improving C++ skills. Get a basic understanding of optimization techniques in ray tracing Challenges and solutions

Lambda Engine

Custom engine project made during Block A in Year 2 at BUAS. The engine is made in C++ with support for scripting in Lua. The engine supports serialization, a CPU based particle system, resource manager, GLTF loading, entity component system integration using entity, complex scene hierarchies, and much more. Goals and Motivations Technical Goals: Explore fundamental ray-tracing concepts such as intersection checks, shadows, lighting. Gain experience on CPU based renderers while improving C++ skills.

Owlet

Custom tech engine project that ended up with an RTS game during Block D in Year 2 at BUAS. The engine is made in C++ and DirectX12 with hardware accelerated ray traced shadows using DXR. Worked on the material system, grass system, particle system, procedural sky and post processing effects tools and editor for all the systems mentioned.

MowDown

Unreal Engine game made in a team project during Block D in Year 1 at BUAS. Worked on the grass-cutting system, other mechanics(respawn, shoot, movement) and developed tools for play testing/design such as a heatmap that shows where players spend most time during a play session.
