Image rendering is the process of generating a visual representation from a model or data. This can involve converting 2D images, 3D models, or other forms of data into a format that can be displayed on a screen. Rendering is essential in various fields, including computer graphics, video games, and simulations, where realistic visuals are required. There are different techniques for image rendering, such as ray tracing and rasterization. Ray tracing simulates the way light interacts with objects to create realistic images, while rasterization converts 3D models into 2D images by projecting them onto a screen. Both methods have their own advantages and applications.
