GFX-Engine

This tutorial demonstrates three different raycasting approaches in GFX-Next and explains when and why to use each of them. It introduces the underlying concepts behind ray queries in the engine and then walks through each approach with practical examples, highlighting their strengths, limitations, and typical use cases. The tutorial compares factors such as performance, accuracy, and integration complexity, helping developers choose the most appropriate method for tasks like physics queries, visibility checks, or gameplay interaction. By the end, readers will have a clear understanding of how raycasting fits into the GFX-Next architecture and how to apply each approach effectively in real projects.

The following example shows a minimal but complete GFX-Next application structure. It demonstrates the essential building blocks required to start and run an application, including engine initialization, application setup, and the main execution loop. The example is intentionally kept small and focused, making it easy to understand how the different parts fit together while still reflecting real-world usage. By studying this structure, developers can quickly grasp the recommended entry points, control flow, and responsibilities within a typical GFX-Next application and use it as a foundation for more complex projects.

This article describes how a GFX-Next application is structured and how the game loop is executed. It breaks down the overall application layout, including initialization, system setup, and shutdown, and explains how these phases relate to the lifetime of
