Hi! I'll answer some questions... > 2) > The release I was working on had a bug rendering transparent objects. (Rendering order was wrong, opaque objects placed > behind transparent objects stayed invisible). Is this fixed ? This is not bug and never been. Try to read more closely Java3D API documentation (javax.media.j3d.View, javax.media.j3d.RenderingAttributes, javax.media.j3d.OrderedGroup).

Ok, that's some time ago...) We have fully commercial project by using Java Web Start (automatic detection for JRE installed and it's installation if need): http://www.schmalzl-massivhaus.de/3d/index.html http://homepages.nsys.by/~yvgtest/NewHouse/WebStart/skis_index.html By the way first project contains a lot off transparent objects. > 4) > What about scene loaders ? The only (non commercial and usable) one I know is the VRML loader from NSCA. > Do know any alternatives (also commercial) ? I used standard Wavefront OBJ-loader earlier (include in Java3D SDK), but when our scenes becomes realy complex and need for complex interactivity, we came to write self loaders for every project (loaders from modified OBJ and ASE formats). > 5) > Any other noticable points ? I thik so Java3D is very usefull for create not very complex real time rendering players with different interactivity for Web-presentation or for local presentation. There are a lot usefull and really working 3D technologies embeded in Java3D already. Now we can create 3D applications more easier with Java3D than C#. For example, I and one 3D-designer can create 3D-presentation of non-complex device (video cam, CD-player, mobile phone etc.) for 1-3 days straight off (without universalization process). Regards.
