Problem with the rotation

Anonymous — Wed, 07 Jul 2010 12:57:39 GMT

I'd like to rotate a column around both of X and Z axis, give the possibility to the users to adjust the angle of the column.
My problem is that I need to use one ROT after the other and the first rotation, e.g ROTX change the frame of reference of course so a single ROTY couldn't do what I need.
So I defined the new Y axis (0, Y, Z) in the changed frame of reference and I've tried the ROT 0, Y, Z, Beta but it rotates the column around the original Z axis.
It should be just mathematics... And I'm sure I'm not recognize some evidence.

Do anybody has any idea?

Hi,

I may be too tired but I don't get what you want to achieve. Can you include the GDL script you have and a screenshot with some additional drawing showing the problem?

In general, there are 2 things you can do with additive rotation. Modify their ordering or multiply the second angle by the co-sinus of the first angle.

Someone will find out what you need as soon as we understand the problem:)

Regs,

Hi,

thanks to trying to help me here too.
I'm sure somebody will know why it's not working as I'd like it to work.

You've already received the object so you saw the scripts.
Thanks again,
Mindless
