Advanced Tutorial

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.
