0Today we covered two very important topics:
1) How to multiply a matrix and a vector, which allows us to finally understand how transformations take place numerically (translation, rotation, and scaling)
2) How to draw an invisible line through the world to see the first thing it hits. Super useful for allowing the player to interact with the world, including shooting people with hitscan weapons.
