Subject: java 3d moleclue viewer
hello all;
I am programming novice and
In the effort to orientate myself with java3d
I have been working on a ball and stick 3d molecule viewer
(which was originally created integrating vrml on top of java)
and I have hit a stump . while I cant offer you cash awards for
your help.....I can get religious and great ask that software engineer
in the sky to bless you with all that your hearts desire (smile)
the original version allowed for the generation and deleting
of molecules using a vrml switch node .. viewing combinations would be
rendered depending if the switch was set to 0 or 1 ... for instance
m_mainSwitch = (EventInSFInt32)switchArray[0].getEventIn("whichChoice");
m_mainSwitch.setValue(0);
since there is not this sort of boolean function in j3d's switch
I tried creating a switch with a child_mask ; all geometry being connected
via a tranform node ( similiar to the fourbyfour game)...when I added
it to the branch group I got a null pointer exception.....
I want to create 5 separate branch groups and
rendered them out in a six with the type of on/off control of
each branch groups objects like vrml .....
Is the j3d switch neccessary or is there a more efficient way ?
thanks in advance
