Resumo

Introduction: Pixel art has been explored since the early development of 2D computer graphics and remains a popular aesthetic, particularly in video games. However, reproducing this style in real-time 3D environments remains challenging. Objective: To develop a shader that emulates pixel art aesthetics in real-time 3D while preserving visual detail. Methodology: The proposed approach uses priority maps to dynamically adjust the texture level of detail (LOD) based on object distance and viewing angle, combined with a post-processing stage for object outlining. The visual results are evaluated through user-perceived quality testing (n=62). Results: The proposed method, Pixelat3D, showed a significant improvement in user preference across most evaluation scenarios.
