Purpose¶

SoTrackballManip is derived SoTransform (by way of SoTransformerManip). When its fields change, nodes following it in the scene graph rotate, scale, and/or translate.

As a subclass of SoTransformerManip, this manipulator also has a 3D interface to edit some of its fields. In this case, the interface edits the rotation and Scale Factor fields.

A manipulator differs from a dragger. When you move a dragger, no other nodes are affected. When you move an SoTransformerManip, other nodes move along with it.

Output Fields¶

self¶

name: self, type: SoNode¶

Parameter Fields¶

Field Index¶

Center: Vector3

Rotation: Rotation

Scale Factor: Vector3

Scale Orientation: Rotation

Translation: Vector3

Visible Fields¶

Translation¶

name: translation, type: Vector3, default: 0 0 0¶: The translation is given by the translation field.

Rotation¶

name: rotation, type: Rotation, default: 0 0 1 0¶

Rotation of the manipulator.

Three lines along the x, y, and z axes form the central star shape, which you can manipulate with the mouse to rotate.

Scale Factor¶

name: scaleFactor, type: Vector3, default: 1 1 1¶: The small cubes are an SoScaleUniformDragger, tied to the Scale Factor field.

Scale Orientation¶

name: scaleOrientation, type: Rotation, default: 0 0 1 0¶: Scale orientation of the manipulator.

Center¶

name: center, type: Vector3, default: 0 0 0¶: Center of rotation and scale of the manipulator.
