3D rendering is the process of obtaining an image of the model using computer software. A 3D rendering is the result of realistic 3D visualization. Put simply, it’s like taking a photo of a model in a specific setting, from a chosen vantage point and with the desired lighting. Rendering is the final critical step in giving the final look to any 3D scene. Specialized software allows running and implementing this process - with its help, 3D models and scenes are converted into a 2D image.
