In gsimchoni/mocap: R interface to parsing and plotting Motion Capture files from the CMU Graphics Lab Database

Description

This function reads in and parses a AFS Motion Capture file and returns several useful objects

Usage

readASF(asfFilePath, in2cm = TRUE)

Arguments

asfFilePath	path to a .asf file
in2cm	a boolean indicating whether to convert inches to centimeters, defaults to TRUE

Value

a list containing:

skeleton	a data frame containing the details for each bone, e.g. DOF, length, direction, angle - DO NOT USE, use the one returned from readAMC
childs	a named list containing a vector of "children" bones for each "parent" bone
CMatList	a named list with the C and Cinv angle-axis matrices for each bone
len	the length parameter in the ASF file, scaling factor all lengths, in CMU files always 0.45
