PROFILE

João Pereira

João Pereira developed core gameplay and rendering features for the GameDevTecnico/cubos and cubos-demo repositories, focusing on 3D graphics, input handling, and engine development using C++ and GLSL. He implemented systems such as deferred shading with shadow normal offset bias to improve visual fidelity and introduced raycasting-based interaction for more robust entity detection. João also enhanced developer workflows by documenting asset identification and shadow artifact mitigation in cubos-blog, using RST and JSON. His work included API improvements like an in-class query count method for ECS, reflecting a thoughtful approach to both runtime stability and developer productivity.

Jun 1, 2025

Concise monthly summary for 2025-06 focused on delivering core improvements in the cubos-blog repository, with emphasis on feature delivery and documentation. Key accomplishment this month: introduction of an in-class query match counting capability via a new count method in the Query class. This enhancement enables counting matches directly within the class, reducing boilerplate and external loop overhead. No major bugs fixed this month; efforts were centered on delivering business value through API usability and performance-oriented refinements.
