# World of Cow - University assignment
This is the last assignment of the computer graphics course i took...
Code here is published under the [AGPL-v3](https://www.gnu.org/licenses/agpl-3.0.html)
# TODO
[ ] Create a cow
[ ] Head
[ ] Tail
[ ] Body
[ ] Legs
[ ] Ears
[ ] Nose
[ ] Eyes
[ ] Allow user control of the cow
[ ] Movement - turn and move
[ ] Head
[ ] Tail
[ ] Legs? (optional)
[ ] Change camera position to be cow point of view
[ ] Add popping-floating text of funny cow thoughts
[ ] Add menu
[ ] Adjust ambient light
[ ] help
[ ] quit
[ ] Add multiple objects(that is not the cow)
[ ] User controlled light source
[ ] Add light source
[ ] move the light
[ ] change intensity
[ ] Add Textures and stuff :)
