Mvector * MMatrix

[ben-cal]

Hi,

I found something strange for the multiplication of an MVector by an MMatrix. The final MVector is not translated. That means that the MVector is not turned into an homogeneous one before performing the multiplication. Is it normal?

For example:
(0, -1, 0)t * (Id, (1000, 0, 0, 1)) = (0, -1, 0)....?!?!

Am i missing something?

yes. A vector does not get translated since a vector indicates direction, not position.

Try doing the same thing with MPoint and it should work since a point indicates a position and can therefore be moved.....

Well, seems quite evident...

Thanks,
