mocap-class: A class returned by read.mocap function.

In browarsoftware/RMoCap: Package for processing and kinematic analyzing motion capture data.

Description

A class returned by read.mocap function.

Usage

read.mocap("file.name.bvh")

Format

a list containing:

• Joints - list of joints,

• Time - vector with time series,

• FrameTime - value of time interval between samples,

• Frame - samples count.

Each joint is a list that contains:

• Nestdepth - level of joint in hierarchy,

• Name - name of the joint,

• Parent - id of the parent on the list, root joint has parent = -1,

• Offset - 3D vector with offset from parent joint,

• Nchannels - number of data channels (6 from root, 3 for other or 0 for end point),

• Order - rotation order (accepted orders are XYZ, XZY, YXZ, YZX, ZXY or ZYX),

• Dxyz - matrix with direct kinematic displacement (calculated from original data),

• RawDxyz - matrix with direct kinematic displacement, present only in root joint,

• Rxyz - matrix with rotation in degrees of hierarchical kinematic model,

• Trans - list of rotation - translation matrices that are used to recalculates hierarchical to direct kinematic model.

Examples

#an example BVH file
data("heian.nidan.bvh")
#write file to the disc
f <- file("heian.nidan.bvh")
writeChar(con = f, object = heian.nidan.bvh)
close(f)
#read hierarchical model stored in BVH file
heian.nidan <- read.mocap("heian.nidan.bvh")
summary(heian.nidan)
