Using Generic 6 DoF Joints
By default, all six degrees of freedom in the Generic joint are unconstrained, which means that when you first
set the joint, it has no effect at all. If you took the next logical step in the preceding example and experimented
with switching the joint type to Generic 6 DoF, you may have gotten a bit of a surprise when Cube.001 just
dropped into oblivion with no apparent connection to Cube at all. To constrain them, click the button corres-
ponding to the degree of freedom you want to constrain, and set minimum and maximum values for its range.
If you leave the default values of 0 and 0, the object will be fully constrained in that degree of freedom. For
linear values, the units are Blender Units. For rotation values, the possible range is from -5 (representing a
180-degree counterclockwise rotation) to 5 (representing a 180-degree clockwise rotation). For example, in the
settings shown in
Figure 8-52
,
all the buttons are depressed, so the object would be prevented from moving in
any degree of freedom except rotating 36 degrees in either direction around the x-axis.
