Updating/Editing Tranformgroup while persisting X and Z but updating only Y , JAVA3D

[Jibby Lala]

Hi,

i have a TransformGroup

which i set somehow:

 (1.45, 0.0, 3.25)

later i want to set only Y value on this which you see above i didn't

so now i want to get something like

(1.45,5.50,3.25)

how to set this 5.50, keeping other two values same/like before.

which functions i use, which transformations i apply ? while when i m trying to

 (0.0,5.50,0,0)

i am getting :

(0.0,5.50,0,0)

NOT THIS :

(1.45,5.50,3.25)

load of thanks.

How familiar are you with linear equations, matrices and vectors?

No i have no knowledge, the knowledge what i had i m applying since one week but failing while i m bad in "java3d". i thought this could be achieve by applying certain functions from java3d
