VFX vs CGI

VFX and CGI are both concepts in use from the very starting of the entertainment industry. The film industry uses VFX for making scenes that otherwise would be impossible like creating a scene with dinosaurs. CGI on the other hand is related to creating models of different types of objects and then rendering their digital images. Toy story was the first film completely animated using CGI. With the advancement of technology, people are focusing on the business aspect of CGI and VFX on a large scale and they are ready to invest in these technologies. So let’s understand VFX and CGI in detail.
