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

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

Hi,

thank's a lot for the mail. I have read it with with a lot of care.

I'm using linux, and I would like to do a Open source program. So, any=20
propietary or Windows program it's no a way to me.

I have looked the link of Sandy Ressler, and I think that it's very=20
interesting to me. One problem that I found always with lookat it's that =
I=20
cannot view a lot of vrml files. For example some of the Sandy Ressler's =
webs.

Otherwise, I begin to rethink my master thesis, and maybe I use a java3d =
to=20
view the scenes. I don't know.

Than's ,

best regards,

Leo
