Hi guys! I have posted a few time about having problems with picking of VRML object loaded with the XJ3D loader (and the Sun one for that matter as well!) I am certain I have got the picking routines worked out O.K. and I have put aside my main project to concentrate on this problem I keep getting.
The main problem is when picking a VRML object imported with a loader. I have written a test file that creates a basic simple Universe and added a a Java generated Shape3D to it that I can pick and get information about the intersection with he pick ray etc perfectly. within the same file (commented out during this test) I also have a VRML shape that is imported and capabilities set on the shape to allow for picking. when this imported shape is added to the scene and I try to get information about the pick target I get silly results. I would love it if someone would be kind enough to have a look at it for me. I can put the VRML file and java files into a zip file (to save space) and mail them to anyone willing to have a look at it for me! I have not attached it to this mail to save peoples space in their inboxes! This problem has been driving me crazy as it just does not make sense I have tried .pickClosest .pickAll .pickAllSorted and even after trawling trough the outputs for possible correct readings I can not find a complete set of x,y,z local readings that I require! Any offers of assistance would be much appreciated.
