The vector dot product. This saucy little number is gonna turn your world upside down, project it, and other such bullshits. Super powerful math stuff do not missit.
Contents
Topics
Part 1
- Vector dot product
- Collision rebound physics calculation via vector operations
Part 2
- Detecting collision
- Implementing vector collision response (rebound) calculation
Video Timestamp Index
Tutorial 3.1
- Introduction: using the vector dot product for rigid body physics problems 0:28
- E.g., ball bouncing off a wall (line in 2D) with an arbitrary inclination
- Using vector operations instead of angles & trigonometry
- What is a dot product? 2:52
- Basically: take vectors j and i: how much does a line j go in the direction of i
- If j and i are perpendicular, their dot product is 0
- How to calculate the dot product 5:54
- Most common usage: "dot with a unit vector" 10:51
- Determines how much a vector is going in the direction of the unit vector
Tutorial 3.2
- Introducing the simuluation setup: plank and balls 0:38
- Coding the
Plankclass 1:08 - Coding the
Ballclass 4:08 - Spawning new balls and destructing when out of bounds 5:24
- Detecting ball collision 6:06
- Resolving ball collision (bounce) 15:20
- Homework assignment 18:50
