++Motion Capture Production (EVarts 5.04)
- Load a previous marker set (project (.prj) file)
- Marker set will be visible in post-process tab
- The number of markers will directly reflect the number of tracks in your track(.trc) file
- this will translate to points on the skeleton rig
- depending what your final destination for your Motion capture is, this may be dictate from the model being animated (if it is already created or not)
- in either case, the data can be massaged later in the pipeline (better to have more)
- Calibration L-seed - switch to calibration tab
- Turn on the cameras, put the L-device on the floor, connect to cameras
- "Run" the cameras for a couple seconds
- Mask out
- switch to 2d mode, for each camera mask out any extraneous areas using middle mouse button (wheel)
- for each camera, use tools ==> camera settings, to asjust the threshold to approximately 300
- repeat masking
- wand, floor, ROM
- Data output, capture
- EVarts 5.04 Post production
++Autodesk MotionBuilder 7.5
- inputting TRC data
- cleaning up TRC data
- animation
