Quaternions

[farshizzo]

In my previous post I explained what the values mean. So given the quaternion rotation of [0,1,0,0], this would mean a 180 degree rotation around the Y axis (2 * acos(0) = 180 degrees). Printing the euler and axis-angle values of the main view after applying the quaternion will confirm this. Adding the following code at the end of the script:

print viz.MainView.getEuler()
print viz.MainView.getAxisAngle()

resulted in the following output:

[-180.0, 0.0, 0.0]
[0.0, -1.0, 0.0, 180.0]

FYI, Vizard color values range from 0-1, not 0-255.
