vrml.eai.field
Class EventInSFRotation

java.lang.Object
  vrml.eai.field.BaseField
      vrml.eai.field.EventIn
          vrml.eai.field.EventInSFRotation

public abstract class EventInSFRotation
extends EventIn

Reference to a SFRotation event-in slot. Use this class to write values into SFRotation event-in slots.

The following example demonstrates how to rotate the children of a Transform node 180 degrees around the y axis:

 vrml.eai.Node transform = ...;
 vrml.eai.field.EventInSFRotation set_rotation = (vrml.eai.field.EventInSFRotation)transform.getEventIn("set_rotation");
 float x = 0.0f;
 float y = 1.0f;
 float z = 0.0f;
 float angle = (float)Math.PI;
 float[] rotation = new float[] { x, y, z, angle };
 set_rotation.setValue(rotation);

Constructor Detail

EventInSFRotation

protected EventInSFRotation()

Default constructor. This method is protected, i.e. you cannot create new instances of this class. The only way to get instances is via the Node.getEventIn(java.lang.String) method.

Method Detail

setValue

public abstract void setValue(float[] value)
                       throws java.lang.ArrayIndexOutOfBoundsException

Sets the value of a SFRotation event-in slot.

The following example demonstrates how to rotate the children of a Transform node 180 degrees around the y axis:

 vrml.eai.Node transform = ...;
 vrml.eai.field.EventInSFRotation set_rotation = (vrml.eai.field.EventInSFRotation)transform.getEventIn("set_rotation");
 float x = 0.0f;
 float y = 1.0f;
 float z = 0.0f;
 float angle = (float)Math.PI;
 float[] rotation = new float[] { x, y, z, angle };
 set_rotation.setValue(rotation);
 

Parameters:

value - The new rotation value. This is a float array of at least fout elements. The first three elements are the x, y and z coordinate of the rotation axis. The fourth element is the rotation angle, in radians.

Throws:

java.lang.ArrayIndexOutOfBoundsException - when the value array contains less then four values.
