Actually a few minutes after I posted my question I visited that page. I had a feeling it was the old "gimble lock" scenario. My solution was if my model was pitched + or - 90, then I adjusted it to be + or - 89.5 ... this kludge seems to fix the problem (ie. my eye doesn't notice the jump). When I have some more time I'll have to read up on a better way to fix it. Nick. |
