tolocal(),toworld() function for direction vector

[dongju.jeong]

The node's toLocal () and toWorld () functions also include distance calculations.  (it seems to be for position vector transform).

 

Are there functions such as toLocal (), toWorld () for the direction vector?

 

I know how to calculate it , but after I found that there was a toLocal () function, I was wondering if there is a function for dirction.

Hi, dongju.jeong,

Unfortunately, there is no such function.
About "include distance calculations": if you are worried about performance, then don't. Source code of the toLocal() method is quite simple: { return inverse_world_transform * point; }
There are only 9 multiplications and 9 additions (unless we use SSE).

Best regards,
