Rendering is the process of generating an image from a model by means of computer software. This involves converting 3D models, which are created using various design tools, into 2D images that can be viewed on screens. The rendering process includes adding textures, colors, and lighting effects to create a realistic or stylized representation of the model. In the context of computer graphics, rendering can be used in various fields such as video games, animation, and architecture. Different rendering techniques, like ray tracing and rasterization, are employed to achieve specific visual effects and enhance the overall quality of the final image.
