Animated rotation node.
The SoRotor class is derived from SoRotation, so it applies a rotation to the current transformation. Using engines connected to the realTime global field, the rotation value is animated over time, achieving a spinning effect. The period of the rotation can be adjusted by changing the speed field.
The current rotation at any time is available in the rotation field, inherited from SoRotation. This field can also be set to specify the axis of rotation.
Note that unless a non-zero rotation is specified for the rotation, the node will not know which axis to use. For example, to set a rotor to spin about the y-axis, use the following:
Any non-zero value can be used for the angle.
rotation | 0 0 1 0 |
speed | 1 |
on | TRUE |
SoGetMatrixAction
Returns transformation matrix specified by the rotation.
SoRotor::SoRotor | ( | ) |
Creates a rotor node with default settings.
static SoType SoRotor::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoRotation.
virtual SoType SoRotor::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Reimplemented from SoRotation.
Allows applications to enable or disable the motion easily.
Defines the speed of the rotor, in revolutions per second.
