We know you might be trying to figure out what is the link between the two fields but there is a lot of connection. It is a very strict rule that any film which uses an animal or a bird has to get complete clearance from the ‘Animal Welfare Board Of India’ and this has never been a smooth thing for many filmmakers.
Given the amount of paperwork involved and other formalities, filmmakers find it hard to adhere to the requirement. So, in order to keep the animal welfare headache away, they are seeking the help of computer graphics companies and getting animals created virtually onscreen to the maximum extent.
For example, the latest release Temper shows graphics for dogs in Ali-Saptagiri sequences. Similarly, the soft spoken filmmaker Sekhar Kammula used a graphic dog in his movie Godavari and the crows episode with Brahmanandam in Alludu Seenu was also graphics magic.
Even if they can shoot naturally, they have to go through lot of procedure and clearances which consumes time so all this is turning out to be a blessing in disguise for the computer graphics companies and they are minting their revenues.
