Does this have head tracking working yet ? |

Head tracking is not implemented in current version. |

Michael - looking at the motion capture files I'm using in JimmyRig (from the free CMU motion capture library), the head motion seems necessary for any realism. I'd certainly be open to taping a white ping pong ball on top of a some kind of cap tied onto the head to make it easier to track. In fact, as it's a bit of work to get an outfit suitable for ipisoft anyway, it wouldn't be too much work to glue colored ping pong balls onto ALL the extremities (to easily differentiate right and left), if that would help? Would be great if you could implement that, as I guess the 4 Logitech cameras I bought have turned out to be unsuitable for use with ipisoft (the PlayStation is the one to get now, right), so many of us are going to have to toss our investment in Logitech cameras. [on the plus site, the Logitech camera is very good for watching the birds who have nested able my front door] Thanks! |

I am wondering how you will implement head tracking. I am sure Michael has thought about this. Would a baseball cap work, with a contrasting coloured peak, and perhaps a left side and right side color? Kevin |

Yes, I agree with you there. What I do is track the movement on low res first, then I go frame by frame and move the head around and Pose refit it on High Res. Sometimes, when the head does not move alot, I can set the head and just run the tracking at High Res until the head moves more. Setting the head in the right spot also makes all of the rest of the body snap perfectly into place. Yeah, this makes the process alot longer than just not tracking the head, but the end result is far superior. Now, I do most of my clean up also in the IPI program. I have found that fixing bad arm movements manually and then going through and blending any weird movements out manually makes for alot better results and an extremely realistic end movement. I'm not talking about just turning the Trajectory Filtering up when I export the file. After I run the Jitter removal, I again go frame by frame, and If I see any jumps of any of the parts, then I turn up Trajectory Filtering, copy and paste, and that smoothes out that jump in that frame without affecting the whole animation. As I'm sure many of you have seen, occassionally, the arm or whatever will do a 360. Using the technique of blending, as I just mentioned, can fix these 360 spins. It would be nice to see the pose tab window look more like a graph of the parts motion, rather than just numbers. |

Hi.. Please see my post about manual key frame extraction for creating head rotation data in the community tutorials section. Cheers |

I have a cheap and dirty way to create head tracking. Use the Wii remote and attach it to a hat. The Wiimote is cheap and the libraries are available. http://wiiyourself.gl.tter.org/ . Wii+MotionPlus would be suitable for mocap headtracking. |

Yeah i tried this and it sucks as I couldnt seem to get all 3 axes of rotation working correctly, I think its a 2 axis accelerometer. Its a messy solution anyway as you must record the data in a seperate app and then put it all back together. The new approach I figured out is way easier and creates the correct result.. check it out.. viewtopic.php?f=3&t=4834 Cheers! Alex |
