Due to the server-down issue in glscene NG, I post the problem here, and hoping that someone familiar with Glscene project will answer it.
I need to set the child Direction, Up and Right vectors to point at the user defined value, if the object is not owned that 's if it doesnt have a parent everything is normal because Glscene doesn’t have to calculate the absolute vectors, but in my case object has parent and GLScene implements these three vectors( which so far I couldn’t figured out how) to get the final absolute direction, up and right vectors.
My question is :
What should I set to child vectors before child/parent assignemt to
get the resulting direction, up, and right vectors of child object
to point at user defined value?
For example :
After the child/parent assignment I need to get Up vector of child to point at negative Y axis (0,-1,0).
thanks in advance
