trans

Python operations available from the trans module, used to change the view of the rendered scene.

• rotate(axis, angle): Rotate the scene about the specified axis by the given angle. axis should be 'x', 'y', or 'z'; angle is measured in degrees.

• translate(x, y, z): Translate the scene by the given x, y, and z values.

• scale(factor): Scale (zoom) the scene by the given factor.

• resetview(molid): Sets the center, scale, rotation for all molecules so that the viewpoint is centered on the molecule with the given id.

• get_center(molid):
• set_center(molid, vector): Get/set the coordinates of the center of the given molecule as a Python list.

• get_scale(molid):
• set_scale(molid,scale): Get/set the scale factor used to display the given molecule.

• get_rotation(molid):
• set_rotation(molid, matrix): Get/set the rotation matrix for the given molecule as a 16-element Python list in row-major order.

• get_trans(molid):
• set_trans(molid, vector): Get/set the global translation applied to the given molecule as a Python list.

• is_fixed(molid): Returns whether the molecule with the given id is fixed; that is, whether it is affected by translation, rotation, or scaling. Fixed molecules may still be animated (see is_active in the animate section).

• fix(molid, trueorfalse): Make the molecule with the given id fixed or not.

• is_shown(molid): Returns whether the molecule with the given id is shown or not.

• show(molid, trueorfalse): Make the molecule with the given id shown or not.
