Hi Don, re: > At the User's Conference several of us using PCs had problems with > wackiness in the World Coastline background. I remember someone told > us a few simple steps that fixed it. Yes, there are known issues with ATI graphics cards. These problems (which I, for lack of a better term, characterize as 'map zings') are not seen when the IDV is run on machines with Nvidia or Intel graphics cards. re: > Is that procedure written up > somewhere? I didn't find it explicitly in recent FAQs, at least as > straightforward a fix that we all did at Unidata. The following should be found in an IDV FAQ: - start the IDV - click on 'Edit -> Preferences' to bring up the 'User Preferences' GUI - select the 'System' tab - change the 'Java 3D: Enable geometry by reference' value from what it currently is - click on the 'Apply' or 'OK' button at the bottom of the 'User Preferences' GUI - exit and restart the IDV This procedure only needs to be performed once; the preference set will be persistent across repeated IDV invocations. re: > The PC is a brand new high-end Dell with a good ATI/Radeon video > card - latest drivers. You have undoubtedly run into the Java 3D/OpenGL problem everyone who is using ATI video cards (like me) experiences. re: > Thanks, No worries. Please let us know if you run into any problems when performing the configuration above.
