3D Fundamentals Tutorial 2

In this video we lay the groundwork needed to represent and transform positions and 3D space, we define the relationship between our 3D space and the screen coordinates, and we setup a data structure to hold our test cube geometry.

• Fix an error in Mat2.h (vector * Matrix multiplication) 0:16
• Introducing 3D space 1:57
• Implementing the Vec3 class 3:19

• Inherits from Vec2 (z-component added)
• Overload all operators for 3D
• Advantage of inheritence here: enables passing Vec3s into functions that accept Vecc2& references

• Calculating the length of a 3D vector (i.e., in R3) 4:57
• The Mat3 3D Matrix class 5:57
• Setting up the coordinate system 7:37
