[Bf-committers] call for coder 1. integrate BioMotionLab walk cycle 2. go deeper in motion analysis

[bjornmose]

Hi,All

There are 2 projects I'd like to suggest

1.

Make user interface for the python script 
https://github.com/bjornmose/BioMotionLab2Blender

2.

Dive deeper into motion analysis, mathematics and explore data 
reduction, recovering relevant data. Mayor focus is on 'relevant'. In 
Video / Audio streaming these methods are common and the elder of us 
know a device called equalizer .. some knowledge from there can be used 
to modify animation data .. hum too much .. but ask if you think  you'd 
like to know more

Hi,

I see! Motion capture disappeared a bit from my radar... it's really 
best if you try one of the dev channels to get people involved. That can 
be bf-committers or the new devtalk.blender.org forums!

Regards,

-Ton-
