Hi guys;



I'm new user of this forum. I came in manily in search for some answers.



For the first - may I modify fvec.h header for use in my own library? Does licence permits this? It say "all copyrights reserved etc ....



/**

***

**/



I really wonder about "can not be examined" part - I am not allowed to look at it?????



My modification consist of simply adding a nameles struct to the class so I can easier access members. Something like this:

class F32vec4

{

//protected:

public:

union{

__m128 vec;

struct { float x, y, z, w; };

};



(....)




So I can do something like this: F32vec4 a; a.x = 3; ... etc.
Secondly how are comparisons with this class done? I see there is no " == " operator implemented. I can't do something like this:



F32vec4 a, b, c;



if( a == b)

do somethign ...



I wonder how ppl do comparisons with this class & how can I implement "==" operator with simd instructions. Yes I would also lilke to put it into fvec.h file.



And also some typedefs like:



typedef F32vec4 vec4f;



Am I aloud to do that according to licence?



best regards
