Yet another Vector and Rotation notes

I put pages with Unity-specific stuff about using vectors and rotations - code using common math; AngleAxis, local space, RotateTowards .. . Well, there's a table of contents. I had old notes lying around I thought would be easy to clean up and post. Ended up being nine 4-9 page sections.

http://www.taxesforcatses.com/vectorW/TOC.html

Here’s my literature search:

o https://docs.unity3d.com/Manual/VectorCookbook.html is pretty good for what it does, but is short and written from more a mathematicians perspective (for example, it covers dot product instead ofVector3.Angle.)

o The video at https://unity3d.com/learn/tutorials/topics/scripting/vector-maths
just covers part of that same vector cookbook stuff.

o https://docs.unity3d.com/356/Documentation/ScriptReference/index.Vectors.html is a very short into to vector contructors and programming - not how to use them.

o youtube.com/watch?v=0KUhzde-INY comes up high in a google search as vector2 guide. It’s a 4-line program using the vector struct.

o http://processing.org/learning/pvector/ also comes up high in a “unity vector math” search. But it’s a mix of writing C++ classes, simple hand-made physics, and simple vector math, for some other graphics engine(?)

o Unity Answers has lots of snippets in response to specific Qs, often with specific solutions without context. Even the ones I wrote, which are fine, are at best one specific context-free fact.

 

Now comes 3 ways: a complete PDF (clickable table of contents) or links to pdf's for each chapter, or an HTML table of contents with each chapter on a page.

Re-edited most of it. Big re-write of first rotations chapter. Added "connect two blocks" example to last chapter.

 

This Manual is so Super Awesome!!

Is it possible to add at the end of the rotation section this:

• Without using physics and using C#
  
• Difference between Rotate and Rotation
  > Rotate: adding rotation angles to the actual rotation? spin
  > Rotation: rotate to a final fixed direction angle using the global world space? fix
  
  
• How to Set Globally the game object
  > to a fix rotation in world space.
  > and make spin it in world space adding angles.
• How to Set Locally the game object
  > to a fix rotation
  > and make it spin it local space.
  
  
• How to Get Globally the game object
  > the fix rotation in world space
  > and get the spin difference.
• How to Get Local
  > fix rotation
  > and the spin difference.
