I know we don't all have beefy computers, but I'm not having any performance problems with similar geometry & number of transforms -- I'm morphing, translating, rotating also.
Anyway, this is a little off topic, but is there a consistent benchmark that we can use here to help expectations of folks when it comes to their own configurations? or could/should one be developed? to me, it's hard to know whether or not it's their program or their hardware that's hurting their fps. have a good one Zaki ----- Original Message ----- From: "RWGRAY" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, July 06, 2002 8:14 AM Subject: Re: [JAVA3D] Trouble with Link/SharedGroup - is it a Java3D bug?? > I too have had "problems" with Link/SharedGroup. > > Not so much "problems" but disappointment with memory usage. > > I had thought that by using Link/SharedGroup I could save a lot of memory > usage.
