Re: [openvrml-develop] Does OpenVrml ......

[Leopold P. <le...@wo...>]

Hi,

thank's for the answer. You have mentioned that you have tested lookat and 
Xj3D and lookat wins performance wise.

Here, there are some people that proposing to develop this project in java. 
It will win portability, so we could use it in Irix, Solaris, Linux and 
Windoze. But, I'm a bit afraid, because I think that by now, java has a lot 
of limitations about the performance. So, if I would like to make a simulator 
of a robotic arm, with a lot of calculations (paths, kinematic inverse, etc) 
and after, I have to do all the work of representing it using a (more or 
less) realistic scene, java maybe is not an option, and I need to go 
necessary to C++/openvrml. It will be great, if someone have 

Do you have tested some complex scene in java and in lookat? there's a lot of 
difference?

Best regards,

Leo
