Part 2/10:
At its core, ray tracing is a computational method that simulates the travel of light rays as they bounce off surfaces and interact with materials in a scene. When creating a digital environment, such as an interstellar battle or a fantasy kingdom, artists meticulously model every object, applying textures and positioning them relative to light sources. This is followed by the rendering process where the scene is transformed into a 2D image through extensive calculations regarding light interaction.
