Constructor Detail

AtomGroup

public AtomGroup()

Default constructor is not usable

AtomGroup

public AtomGroup(UnitCell cell,
                 int s,
                 float r,
                 javax.vecmath.Color3f dc,
                 javax.vecmath.Color3f ec)

Creates sets of atoms for a unit cell. Atoms either lie on the lattice points or on the hole positions.

Parameters:

cell - unit cell

s - atom type (0 primary coordinate sites; otherwise hole sites)

r - atom radius

dc - atom diffuse color

ec - atom emissive color

AtomGroup

public AtomGroup(int nx,
                 int ny,
                 float r,
                 javax.vecmath.Color3f dc,
                 javax.vecmath.Color3f ec)

Creates a single layer of closest-packed atoms

Parameters:

nx - number of atoms along x direction

ny - number of atoms along y direction

r - atom radius

dc - atom diffuse color

ec - atom emissive color

Method Detail

getAtomTranslation

public javax.vecmath.Vector3f getAtomTranslation(int idx)

Returns virtual world translation of the specified atom.

s - visibility state

setAllVisible

public void setAllVisible(boolean s)

Sets the visibility of all atoms

Parameters:

s - visibility state

setRotation

public void setRotation(float x,

                        float a)

Set rotation for the entire group.

setTranslation

public void setTranslation(float x,
                           float y,
                           float z)

Set the translation for the entire group.
