Due to these facts, the software is usually extremely expensive. It is a time-consuming and power-hungry process. Powerful software is required to perform 3D rendering.

It adds the finishing touches to the design – it gives polish and is what is required to make an animation or design work. The rendering process is the last part of creating 2D animation or 3D designs. “3D computer graphics process of automatically converting 3D wire frame models into 2D images on a computer.” 3D rendering is an important part of CAD design, CGI, and other design-based processes.
