Android 3D game engine

Complete 3D game engine built from scratch using Java and GLSL. It features state of the art per pixel lighting and advanced materials, including support for normal mapping and parallax mapping.

The engine provides all the utilities for model and texture loading, particle systems, on demand dynamic shader creation and compilation, AdMob integration, sound fx and music, scene management, settings, and user input.

All the source code for the engine, incluing the tools, will be uploaded to GitHub eventually.

Achieved the highest grade in the thesis: Ray tracing based multi-platform library for photorealistic 3D scene rendering.


I have been developing software for more than ten years now. During these years I have developed C++ embedded systems for an IoT platform and ray-tracing based rendering engines, Java large enterprise applications for investment and insurance and for visually creating travel guide mobile apps, desktop emulators for the GSM network and Android 3D games, C# 3D tools and Kinect-based gesture interaction systems, and JS web 3D visualization libraries based on WebGL.

All these years I have been driven by a constant will to face new challenges and learn new programming languages and frameworks, and jump out of my confort zone constantly. My broad and diverse experience is the result.

Born in Spain, now I live in London following the buoyancy of the tech scene here, where all kind of new and exciting technologies are within reach.
