Overview

In my thesis, "Developing 3D Pixel Art Rendering", I created a new technique for rendering 3D environments that capture the essence of traditional 2D pixel art. This project, driven by the growing interest in pixel art, blends low-poly 3D models with pixel-perfect visual clarity, overcoming common issues like pixel creep and jittering. Through custom shaders, camera techniques, and post-processing adjustments, I developed a unique rendering style, termed Polyx, which delivers a nostalgic, 2D-like aesthetic in real-time 3D spaces. The outcome includes a playable prototype and comprehensive documentation, offering an accessible method for developers interested in incorporating this distinctive visual style into their projects.

This project explores the development of a novel rendering technique for 3D pixel art, a visual style that remains largely unexplored despite the growth of modern game engines. While tools like physically based rendering and toon shading are well documented, 3D pixel art lacks accessible techniques and standardized workflows, creating a gap for developers interested in this aesthetic.

The thesis presents the design and implementation of an open-source rendering solution that reproduces the look of pixel art within a 3D environment. It details the technical pipeline, rendering methods, and artistic considerations required to achieve a consistent pixelated style in real time. The work focuses on balancing visual fidelity, performance, and stylistic coherence, ensuring the technique is practical for game development.

To validate the approach, the system is applied in a playable game prototype, demonstrating how the rendering technique integrates into a real production context. The project not only delivers a working solution but also provides comprehensive documentation, making it accessible for other developers to adopt and extend.

Overall, this thesis contributes a new graphical pipeline and practical implementation that positions 3D pixel art as a viable and distinctive style for modern games, bridging the gap between retro aesthetics and contemporary 3D rendering.
