I Don't Need Math! I'll Just Make Videogames When I Grow Up!

I Don't Need Math! I'll Just Make Videogames When I Grow Up!
The sweet summer child who thinks they can skip math and just "make cool games" is about to get absolutely demolished by reality. Game development is basically applied mathematics in disguise - vectors, quaternions, matrices, physics simulations, and collision detection algorithms waiting to ambush you like final bosses. The bottom panels show the major game engines and graphics libraries (Unity, OpenGL, C++, and what looks like PhysX) literally laughing their logos off at this naive declaration. They're like "Sure buddy, good luck implementing that 3D rotation without understanding linear algebra or calculating that trajectory without differential equations!" Game dev without math is like trying to build a skyscraper with popsicle sticks and wishful thinking. Those complex formulas on the chalkboard? That's just the tutorial level.

Include Linalg... In The Next Decade

Include Linalg... In The Next Decade
The excitement-to-disappointment pipeline is real. You spend hours hunting for that perfect C++ feature to solve your problem, only to discover it's coming in C++26... which is years away. It's like finding out the solution to your current deadline is scheduled to arrive sometime after your retirement. The crushing realization that you'll have to implement your own janky workaround (again) instead of using that shiny new linear algebra library. Welcome to C++ development, where the future is always bright but perpetually out of reach.

Generational Linear Algebra

Generational Linear Algebra
The mathematical family tree of complexity! Grandpa Tensor is the wise old-timer who's seen it all—multidimensional data structures that make young programmers cry. Dad Matrix is the middle manager who organizes everything in neat rows and columns. Son Vector is just trying to find his direction in one dimension. And baby Scalar? Just a single value with no ambition yet—but hey, at least it's easy to handle during those 2 AM debugging sessions when your AI model is throwing tantrums. Evolution went from "I need a PhD to understand this" to "even JavaScript can handle this one."

Saves Computing Power By Transcending To The 4th Dimension

Saves Computing Power By Transcending To The 4th Dimension
Left side: Regular 3D rotation math with sines and cosines. Complex but manageable if you've ever implemented a camera system. Right side: Quaternions. Four-dimensional math that makes rotation calculations significantly more efficient but looks like someone dropped acid while reading a linear algebra textbook. Game developers be like: "Yes, I understand quaternions perfectly" while secretly copy-pasting code from Stack Overflow and praying it doesn't introduce gimbal lock.

Initialize Your Off Diagonals

Initialize Your Off Diagonals
When you only initialize the diagonal values in your matrix, the compiler fills the rest with garbage that looks suspiciously like scientific notation for zero. Now your matrix is basically a Bond villain—looks impressive in a tuxedo but threatens you with memory garbage and potential matrix inversion disasters. Next time, initialize all your values unless you enjoy playing Russian roulette with your linear algebra operations.
