HypeHype is a game creation platform where you can create, share and play games.

Hilights of my work:

low-level networking architecture based on GameNetworkingSockets and WebSockets & WebRTC
refactoring a 3D game editor into a serializable networked command-based architecture, allowing multiuser editing, spectator support with full UI syncs, autosave, undo-redo
C++ backend managing multiplayer & editor sessions, handling real-time UDP connections from desktop, mobile and browsers, running in Docker, deployed to AWS
multiplayer support, including spectators and host migrations
particle system, analytics system, various editor and app features
game engine profiling and optimizations, interop with Flutter based application front-end UI
low-level multiplatform development including Android, iOS, macOS, Windows, Linux, Web via emscripten

REAL TIME GLOBAL ILLUMINATION WITH VOXEL CONE TRACING

C++, OpenGL 4.5

GitHub

The Crytek Sponza -scene with voxel cone traced global illumination

Voxelized version of the Crytek Sponza -scene.

Another screenshot of the voxelized scene without ambient light.

A full voxel grid containing the Blender Suzanne -model.

A deferred renderer with real-time global illumination with voxel cone tracing.

Voxelization is performed every frame. The voxel grid is a mipmapped 3D texture which contains a voxelized representation of the directly lit polygonal scene. The cones travel through the mipmap levels and gather samples along the way.

Hilights:

voxelization of a polygonal scene
indirect diffuse and specular reflections
soft shadows
ambient occlusion

WAKA WANHA

C++, OpenGL

JavaScript, HTML, CSS

Web

Overworld with a portal access. You can see the following systems: FOV, static and dynamic items, portals, fade in-out screens, inventory, GUI.

Randomly generated dungeon with a enemy spawner. On the right: a debug view into the physical world.

A physics-based roguelike in development, aiming to be as deep as traditional ASCII-roguelikes yet audio-visually polished to be understandable. Will be released as a browser game with backend created in Go. Closed alpha begins during 2024.

Hilights:

based on a custom game engine
C++/JavaScript/Go architecture
procedural generation algorithms
blueprint system for defining scenes including various generator algorithms and gameplay content such as tiles, items, room prefabs, NPC behaviour trees, background shaders, audio ambience with DSP effects
