Graphics rendering is the process of generating a visual image from a 2D or 3D model using computer software. This involves converting data, such as textures, colors, and lighting, into a final image that can be displayed on a screen. Rendering is essential in various fields, including video games, movies, and simulations, where realistic visuals are crucial. There are different techniques for graphics rendering, such as ray tracing and rasterization. Ray tracing simulates the way light interacts with objects to create highly realistic images, while rasterization converts 3D models into 2D images more quickly, making it suitable for real-time applications like video games.
