Text Modify

Change here the position and orientation of a text (or list of texts, previously selected with Text->Select, when Global is pressed), in relative or absolute coordinates. Parameters for empty entries or Local choices remain unchanged.

Translation

The origin of a text object, defined as its top left corner, can be changed using the X, Y, Z entries. The change can be Absolute or Relative (to the former origin).

Rotation

The orientation of a text object, defined by the Euler angles theta, phi, psi, can be changed using the E1, E2, E3 entries. The change can be Absolute or Relative (to the former Euler angles). Euler angles are not addictive, so the text must be rotated back with the old angles and forward with the new ones.

Euler angles in GAMGI are defined as follows: first, the (x, y, z) referential is rotated theta degrees (between 0 and 180) around the y axis, then the referential is rotated phi degrees (between 0 and 360) around the initial z axis, and finally it is rotated psi degrees (between 0 and 360) around the new z axis, always in the direct, counter-clockwise, direction. If the first Euler angle (theta) is zero, the old and new z axis coincide, thus (0, 0, 10) and (0, 5, 5) represent the same rotation.

By default text objects are on a plane parallel to the screen, corresponding to Euler angles (0, 0, 0). For this orientation, Wired (stroked) text objects, and Solid (extruded) text objects in a layer with an orthographic projection, will look exactly as normal 2D text messages.
