Rendering is the process of generating an image or sequence of images from a 3D model. It involves the calculation of lighting, shading, and other visual effects to create a final, photorealistic image or animation. In the context of materials, modeling, animation/rigging, and dynamics, rendering plays a crucial role in bringing these elements together and producing a visually appealing output. It helps to showcase the textures, colors, and details of the objects in the scene, making them look realistic and lifelike. Therefore, rendering is an essential part of the overall 3D production pipeline.
