translateScene(x, y, animationDurationopt, fixedPathopt)

Translate current models by x,y screen coordinates
This translates the models relative to the current view. It does
not change the center of rotation.

Parameters:

Name	Type	Attributes	Description
`x`	number		Relative change in x screen coordinate
`y`	number		Relative change in y screen coordinate
`animationDuration`	number	<optional>	an optional parameter that denotes the duration of a zoom animation
`fixedPath`	Boolean	<optional>	if true animation is constrained to requested motion, overriding updates that happen during the animation *

Example

$3Dmol.get('data/4csv.pdb', function(data) {
    viewer.addModel(data,'pdb');
    viewer.setStyle({cartoon:{},stick:{}});
    viewer.zoomTo();
    viewer.translateScene(200,50);
    viewer.rotate(90,'z'); // will no longer be around model center
    viewer.render(callback);
    });

vibrate(numFrames, amplitude, bothWays, arrowSpec)

If atoms have dx, dy, dz properties (in some xyz files), vibrate populates each model's frame property based on parameters.
Models can then be animated

Parameters:

Name	Type	Description
`numFrames`	number	number of frames to be created, default to 10
`amplitude`	number	amplitude of distortion, default to 1 (full)
`bothWays`	boolean	if true, extend both in positive and negative directions by numFrames
`arrowSpec`	ArrowSpec	specification for drawing animated arrows. If color isn't specified, atom color (sphere, stick, line preference) is used.

zoom(factoropt, animationDurationopt, fixedPathopt)

Zoom current view by a constant factor

Parameters:

Name	Type	Attributes	Description
`factor`	number	<optional>	Magnification factor. Values greater than 1 will zoom in, less than one will zoom out. Default 2.
`animationDuration`	number	<optional>	an optional parameter that denotes the duration of a zoom animation
`fixedPath`	Boolean	<optional>	if true animation is constrained to requested motion, overriding updates that happen during the animation

Source: GLViewer.ts

Example

$3Dmol.get('data/4csv.pdb', function(data) {
    viewer.addModel(data,'pdb');
    viewer.setStyle({cartoon:{},stick:{}});
    viewer.zoomTo()
    viewer.zoom(2,1000);
    viewer.render();
    });

zoomTo(selopt, animationDurationopt, fixedPathopt)

Zoom to center of atom selection. The slab will be set appropriately for
the selection, unless an empty selection is provided, in which case there will be no slab.

Parameters:

Name	Type	Attributes	Description
`sel`	Object	<optional>	Selection specification specifying model and atom properties to select. Default: all atoms in viewer
`animationDuration`	number	<optional>	an optional parameter that denotes the duration of a zoom animation
`fixedPath`	Boolean	<optional>	if true animation is constrained to requested motion, overriding updates that happen during the animation *

$3Dmol.get('data/1fas.pqr', function(data){
              viewer.addModel(data, "pqr");
              $3Dmol.get("data/1fas.cube",function(volumedata){
                  viewer.addSurface($3Dmol.SurfaceType.VDW, {
                      opacity:0.85,
                      voldata: new $3Dmol.VolumeData(volumedata, "cube"),
                      volscheme: new $3Dmol.Gradient.Sinebow($3Dmol.getPropertyRange(viewer.selectedAtoms(),'charge'))
                  },{});

              });
              viewer.zoomTo();
            });
