Product rendering is the automated process of creating a realistic or non-photorealistic picture from a 3D or 2D model through computer software. It is accomplished through the post-processing of a CAD-generated 3D model.
Post-processing incorporates a wide range of factors into consideration to produce the most real-looking images. With the use of an advanced GPU (graphics processing device) to assist the native CPU of the computer the intricate calculations needed to create images through this process are optimized.
3D product rendering is a powerful and versatile way of depicting objects through the use of software to create images with a lifelike level of detail.

Product visualization can be described as a method that involves technology for visualization to view and manipulate 3D models, technical drawings, and other documentation related to produced components and large assemblies of components.
Features Needed to Create a Realistic Rendering
Certain among these characteristics are:
Shading: It considers how the surface appears depending on the lighting angle and intensity. The visual appearance of color depths and textures are greatly affected by the proper shade algorithms.
Texture mapping: This is the real intricate details of how surfaces are "constructed" in reality. Smooth metal surfaces may be simple to replicate, however, something more complicated like furniture or carpet fabric requires a high degree of precision to give a real-life impression.
Shadows: Consider the way a surface appears as light is blocked in a particular manner. It also takes into account shadows that are emitted by the object and shadows cast by the surface of the object.
