Hi, everyone:

Recently, I decided to start a game math series on my blog.
Please tell me what you'd like to read to help me plan out what to write about.

Thanks

Below is a list of written posts and planned topics:

http://allenchou.net/game-math-series/

Vector Math

• “Cross Product” of 2D Vectors
• Vector Reflection (Planned)

Linear Algebra

• Alternate Views on Matrix Multiplication
• How to Eyeball The Inverse of A Matrix
• Block Matrices

Coordinate Systems

• Complex Numbers (Planned)
• Polar Coordinates (Planned)

Quaternions

• Quaternion Basics (Planned)
• Quaternions as 3D Rotations (Planned)

How about something about dual quaternions and interpolating them. Or plucker coordinates!

I think an article on splines (Catmull-Rom..., natural cubic splines...) would fit very nicely with the rest of the material, perhaps right after polynomial approximations.

Another question that pops up a lot is target leading, which in the usual case of constant velocities can be reduced to a quadratic equation by using the properties of the dot product. So perhaps a lesson on the dot product and its applications would be in order. Other applications could be things like ray-sphere intersection, orthogonal projection...

Just some ideas. I'll post back if I can think of any others.
