What is the cheapest and most decent for its money way to set up a body motion capture rig? Which software, which equipment?And a second question: How does Mixamo do it? I mean all those mocap animations... how did they get they them?
>>581558As somebody who has build a super budget mocap set up I think it is safe to say the cheapest option is to just use somebody else's data base. If you can find the animations you need in free libraries like the Carnegie Mellon Motion Capture Database, then use them and don't look back. Link related. Even if they are not perfect for your use case you can manually clean them up and tweak them if they are close enough, you will have to do that same manual clean up on you own files if you are using budget sensors.http://mocap.cs.cmu.edu/If what you need is specific enough no to be roughly covered by somebody else's data base there are a number of cheep solutions. Really the most expensive part is the time you will have to put in setting up, trouble shooting and establishing a pipeline for getting your mocap files to your rigs in a efficient matter. Shoots will produce a lot of data and you need a way to sift through it and pick out the takes you like especially if you are trying to build a huge library for your self. Be prepared to fight with drivers, OS compatible, networking, hard to diagnose USB bandwidth shortages, I have even had a simple 12 volt power supply that was corrupting bvh files by introducing a dirt jitter into one of the sensors.
>>581572So on to some specifics; iPi Soft seem to be the most user friendly solution while still being pretty flexible with what set ups it will take. It is what I went with but it comes with a hefty licencing price. Get your employer to buy it or use the trials. The recording soft ware is free but the "studio" that you use for calibration, process, jitter removal, re-targeting, and export is not. The two main set up it takes is multiple Sony PS Eye cameras or one or more Kinect sensors.My set up uses two Kinect v2 sensors as they provide better results then v1 Kinects, but it requires a dedicated PC with windows 8 and USB 3.0 ports for each Kinect v2 and if you either need to take each one apart and solder on some leads to board inside for an external power supply of spend $40 to $50 each on Microsoft's adapter. All and all I spend about $60 on two used Kinect v2 another $30 on USB 3.0 cables power supplies and a torx security bit set to open the Kinects.If you have any more questions I can go more in depth on the path I took, but it is rough shit. A good experience, great for my resume, as somebody at the start of their career, but a huge time skin.
>>581558>cheapest and most decent for its money wayblender.$10 flip phone.don't expect great results but it will work.
>>581574I'm going to do this next weekend.Thanks man.
>>581574Thanks so much for the answer. I went through the iPi Wiki and a thing is not clear yet.Based on your experience how much impact to the biped result does it have if the actor is fat, skin, tall, short, male, female?
>>581646If you are referring to the difference between the build of your performer and the proportions of you end target rig then I have found it dose not have any effect as it is just the bone roll values that get transferred when re-targeting a rig.But there is a part of the process where they build of your performer dose matter quite a bit. Since the tracking is not based on fixed points (i.e. ping pong balls) it goes on the volume that the performer is taking up. It compares that against and rigged mesh they call an "actor" that has a configurable silhouette, you can see all the basic adjustments in pic related but, there are some more advanced options hidden somewhere. Any how it really matter how close your configured actor is a match for you body type. I was getting bad results on just my feet and it turned out that my legs were longer relative to my height and arm length then what the programs considered average for a male, so the actors feet were about a inch or two higher then my feet in the data. That was enough to result in the feet popping between positions. Fortunately there is a leg length option. Also the tighter your clothing fit the better, since I am in my own home I just strip down to my skivvies.
Where is the other half of the tree?
Don't use mocap. Animate by hand like a nonfaggot.
