Open source Kinect motion capture toolkit

I had developed an open source Kinect motion capture toolkit, and put it on GitHub.
If you want to make your own motion capture system, this is your best choice, it is completely free.

You need to compile it yourself, I only use the it on macOS, you can try compiling it for Linux and Windows, it should work.

I have successfully use it in Blender, here are the steps:
  1. Use the toolkit to generate BVH file.
  2. Import the BVH file to blender.
  3. Bind the character to the armature.
If you are using Rigify's metabone, you just need to adjust the armature slightly, here are the steps:
  1. Select the armature, enter 'Edit' mode, select all bones, press 'Ctrl' + 'N', click 'Recalculate Roll->with Global -Y axis'.
  2. Select the armature, enter 'Pose' mode, rename some bones, let them match the bone names of the BVH armature, and change the rotation mode from 'Quaternion(WXYX)' to 'ZYX Euler'.
  3. Bind the character to the armature.
  4. Use the toolkit to generate BVH file.
  5. Import the BVH file to blender.
  6. Delete the BVH armature.
  7. Select the armature, switch to 'Dope Sheet->Action Editor' interface, attach the motion clip.

Storyboarder, свободный пакет для раскадровки сцен

Студия Wonder Unit развивает открытый пакет Storyboarder, упрощающий проведение работы по раскадровке в процессе подготовки к съёмке фильма/анимации/рекламы или просто для визуализации возникающих идей.

Под раскадровкой понимается создание серии картинок, предварительно визуализирующих состав будущих сцен, показывающих размещение персонажей и важных объектов, и их последовательность в соответствии с сюжетной линией. Код Storyboarder написан на языке JavaScript и распространяется под лицензией MIT c дополнительными исключениями: запрет на продажу и требование указать ссылку на оригинал при распространении.

На днях вышел 13 выпуск программы, которая пока не вышла из стадии бета-тестирования. Бинарные сборки поставляются для Linux (AppImage), macOS и Windows.
