What are the different rendering techniques used in video games?

There are several rendering techniques used in video games, including rasterization, ray tracing, and voxel rendering. Rasterization is the most common, converting 3D models into 2D images. Ray tracing simulates light behavior for more realistic visuals, while voxel rendering uses 3D pixels for unique styles.

Can you explain how ray tracing works?

Ray tracing works by simulating the way light interacts with objects in a scene. It traces rays from the camera into the scene, calculating how they intersect with surfaces and how light reflects, refracts, or is absorbed. This results in highly realistic lighting and shadows.

What are the advantages of using ray tracing over rasterization?

Ray tracing provides more realistic lighting, shadows, and reflections compared to rasterization. It can create complex visual effects like global illumination and caustics, which enhance the overall visual fidelity of a game.

Are there any games that use ray tracing?

Yes, many modern games use ray tracing, including titles like 'Cyberpunk 2077', 'Control', and 'Minecraft'. These games showcase the technology's ability to enhance visual realism.
