Constructor Detail

PointGroup

public PointGroup(float[] xyz)

Constructs a points group with specified coordinates.

The (x,y,z) coordinates of points are packed into the specified array xyz. The number of points is np = xyz.length/3.

Parameters:

xyz - array[3*np] of packed point coordinates.

PointGroup

public PointGroup(float[] xyz,
          float[] rgb)

Constructs a points group with specified coordinates and colors.

The (x,y,z) coordinates of points are packed into the specified array xyz. The number of points is np = xyz.length/3.

The (r,g,b) components of colors are packed into the specified array rgb. The number of colors equals the number of points.

Parameters:

xyz - array[3*np] of packed point coordinates.

rgb - array[3*np] of packed color components.

PointGroup

public PointGroup(float size,
          float[] xyz)

Constructs a points group with specified coordinates.

The (x,y,z) coordinates of points are packed into the specified array xyz. The number of points is np = xyz.length/3.

Parameters:

size - size of cubes used to represent points.

xyz - array[3*np] of packed point coordinates.

PointGroup

public PointGroup(float size,
          float[] xyz,
          float[] rgb)

Constructs a points group with specified coordinates and colors.

The (x,y,z) coordinates of points are packed into the specified array xyz. The number of points is np = xyz.length/3.

The (r,g,b) components of colors are packed into the specified array rgb. The number of colors equals the number of points.

Parameters:

size - size of cubes used to represent points.

xyz - array[3*np] of packed point coordinates.

rgb - array[3*np] of packed color components.
