??There?are?three?vector?classes?and?two?matrix?classes:?vec2?vec3
??vec4?mat3?and?mat4.

??All?the?standard?arithmetic?operations?are?defined?with?‘*‘
??for?dot?product?of?two?vectors?and?multiplication?of?two?matrices
??and?‘^‘?for?cross?product?of?two?vectors.

??Additional?functions?include?length（）?normalize（）?homogenize?for
??vectors?and?print（）?set（）?apply（）?for?all?classes.

??There?is?a?function?transpose（）?for?matrices?but?note?that?it?
??does?not?actually?change?the?matrix?

??When?multiplied?with?a?matrix?a?vector?is?treated?as?a?row?vector
??if?it?precedes?the?matrix?（v*M）?and?as?a?column?vector?if?it
??follows?the?matrix?（M*v）.

??Matrices?are?stored?in?row-major?form.

??A?vector?of?one?dimension?（2d?3d?or?4d）?can?be?cast?to?a?vector
??of?a?higher?or?lower?dimension.??If?casting?to?a?higher?dimension
??the?new?component?is?set?by?default?to?1.0?unless?a?value?is
??specified:
?????vec3?a（1.0?2.0?3.0?）;
?????vec4?b（?a?4.0?）;???????//?now?b?==?{1.0?2.0?3.0?4.0};
??When?casting?to?a?lower?dimension?the?vector?is?homogenized?in
??the?lower?dimension.??E.g.?if?a?4d?{XYZW}?is?cast?to?3d?the
??resulting?vector?is?{X/W?Y/W?Z/W}.??It?is?up?to?the?user?to?
??insure?the?fourth?component?is?not?zero?before?casting.

??There?are?also?the?following?function?for?building?matrices:
?????identity2D（）?translation2D（）?rotation2D（）
?????scaling2D（）??identity3D（）????translation3D（）
?????rotation3D（）?rotation3Drad（）??scaling3D（）
?????perspective3D（）
