Computer graphics are cool, I think?

Graphics Programmer and game developer. I am passionate about the mathematics and science behind computer graphics, with an interest in developing game engines and making games.

C++ C# OpenGL Vulkan Unity / Unreal Engine

Selected work

Five projects, ordered by how proud I am of it.

Aug - Sep, 2026

Game Engine

A C++ game engine built from scratch, currently using OpenGL for rendering with Vulkan planned as a second graphics API. The project is aimed at building a modular engine for game development, with a focus on proper software architecture

It implements core rendering logic and handles C++ memory allocation efficiently, with support for compiling and running games.

+ How it's structured
The engine core owns the graphics, rendering, and input systems, manages the application lifecycle, and runs the main loop. On top of it, an Application layer defines the game-specific implementation with its own init, update, and shutdown behavior. The graphics layer separates the GraphicsAPI, ShaderProgram, and VertexLayout.

Screenshots comming soon.

C++ Ray Tracer

A ray tracer built entirely in C++ with no additional libraries. It's modeled primarily around path tracing, with functionality supporting anti-aliasing, lighting, refraction and reflection, and depth of field.

OpenGL Fluid Simulation

A CPU-based fluid simulation built in C++ and OpenGL using Jos Stam's Stable Fluids method. The project simulates smoke-like fluid behavior by solving velocity and density fields on a grid and rendering the results in real time.

It runs entirely on the CPU right now, with techniques including semi-Lagrangian advection, Gauss-Seidel diffusion solving, pressure projection for incompressibility, and both bilinear and bicubic interpolation for sampling.

+ How the simulation runs each frame
  1. Add forces - external forces are introduced from injected velocity.
  2. Diffusion - the fluid spreads into neighboring cells, producing motion over time.
  3. Projection - the velocity field is corrected to keep the flow divergence-free, since real fluids don't gain or lose volume on their own.
  4. Advection - density and velocity are transported across the grid, following the current flow direction.

Unity Compute Shader Optimization

A Unity compute shader project that renders a 3D graph made of geometric shapes - each cube instanced on the GPU based on where it should sit in a mathematical function, like waves, ripples, and spheres. An HLSL shader colors the cubes based on position, adding depth and variation across the surface.

A companion fractal system uses Unity's Job System to animate thousands of transformations across a large recursive structure without tanking performance, with a second HLSL shader adding color variation so the fractal reads as organic rather than uniform.

+ Notes
Built with the help of Jasper Flick's tutorials at CatlikeCoding, which were a big part of understanding procedural generation, Unity's Burst compiler, and GPU instancing.
A Sphere instantiated with the compute shader.
A Torus instantiated with the compute shader.

OpenGL Lighting Renderer

A renderer built in C++ and OpenGL as a learning project for computer graphics fundamentals. Key features include Blinn-Phong lighting, shadow mapping, cube maps, post processing, depth testing, model loading, and shader creation.

C++ OpenGL Blinn-Phong Shadow mapping

Environmental mapping, reflecting the enviornment around the cube.
Environmental mapping, refracting the light from the enviornment around the cube.
Edge detection, which darkens the surroundings.
Inversion effect, by inverting the texture color.
