Chenarch Posted April 6, 2013 Report Share Posted April 6, 2013 EIAS v8 I have landscape plan I'm trying to illustrate by animating its sectional profiles. During this short animation the camera starts off looking straight down on the plan Yaw Angle 0, then I attempt to orbit to an angled view of the plan. The 'orbit' move starts with frame 31. So camera is stationary for 0-30 frames, then on frame 31, instead of orbiting smoothly, it goes haywire for one frame, then orbits smoothly after that. Any idea what the issue is? This hasn't happened before. Thanks for any ideas on this... Richard Here's the video: http://www.princetondigitalarts.com/v4.mp4 Here's the camera info showing the Yaw Angle going haywire between frames 30 and 31...

Chenarch Posted April 6, 2013 Author Report Share Posted April 6, 2013 Here's the snapshot of the camera info windows at frames 30 and 31, showing the Yaw Angle going crazy for one frame http://www.princetondigitalarts.com/cam_f30_f31.jpg Quote Link to comment Share on other sites More sharing options...
Tomas Egger Posted April 6, 2013 Report Share Posted April 6, 2013 Ola, It's a common 3d application problem, named "gimbal-lock", the correct way to avoid this is parent the Camera in a Effector and then animate th effector.

Chenarch Posted April 6, 2013 Author Report Share Posted April 6, 2013 Thank you, Tomas! The Effector worked. Best, Richard Quote Link to comment Share on other sites More sharing options...
Chenarch Posted April 6, 2013 Author Report Share Posted April 6, 2013 I also watched a very informative video on YT about Gimbal-Lock, and realized I could also just start my orbit from about 80 degrees up and not 90, thus avoiding the issue. Thank you, Tomas! Quote Link to comment Share on other sites More sharing options...
