Detailed Description

The Transform struct.

Note

This struct has been rearranged to use anomymous unions for improved flexibility, but now initializations must be done with and additional pair of curly parenthesis, otherwise some compiler can issue a warning; for example: Transform T = { {{0,0,0}} , {0} , {{0,0,0,1}} };

The 'vector' and 'quaternion' fields have been added only to allow partial assignments like: T2.quaternion = T1.quaternion;

By default this struct contains nested anonymous structs that allow to use {.px,.px,.pz} and {.rx,.rx,.rz,.rw}/{.qx,.qx,.qz,.qw} fields: this requires the C++11 standard (but in my tests g++ and clang++ with -std=c++98 is enough)

There is a definition named NUDGE_NO_ANONYMOUS_STRUCTS that can be used to remove anonymous structs, that usually require -std=c++11 (even if g++ and clang++ seem to work just fine with -std=c++98 in my tests)
