public class PointCloud
extends ColoredNull
implements Renderable, Pickable

This class represents a point cloud. For now, only point locations and a color (for all points the same) can be set, but no normals. The parameter pointSize controls how big points are displayed on the screen.

Constructor Detail

PointCloud

public PointCloud()

Create a new empty point cloud.

PointCloud

public PointCloud(float[] points)

Create a new point cloud and set the points to the provided array.

Parameters:

points - the coordinates of the points

PointCloud

public PointCloud(float[] points,
                  float pointSize)

Create a new point cloud and set the points to the provided array.

Parameters:

points - the coordinates of the points

pointSize - size of a point on screen

Method Detail

draw

public void draw(java.lang.Object object,
                 boolean asNode,
                 RenderState rs)

Specified by:

draw in interface Renderable

getNTypeImpl

protected Node.NType getNTypeImpl()

Description copied from class: Node

This method returns the Node.NType which describes the managed fields of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:

getNTypeImpl in class Null

Returns:

type describing the managed fields of the class of this node

getPoints

public float[] getPoints()

Make a copy of the points and return them.

Returns:

the points

getPointSize

public float getPointSize()

newInstance

protected Node newInstance()

Description copied from class: Node

This method returns a new instance of the class of this node. This method has to be implemented in every concrete subclass.

Overrides:

newInstance in class Null

Returns:

new instance of class of this node

pick

public void pick(java.lang.Object object,
                 boolean asNode,
                 Point3d origin,
                 Vector3d direction,
                 Matrix4d transformation,
                 PickList list)

Description copied from interface: Pickable

Computes intersections of a given ray with this shape.

Specified by:

pick in interface Pickable

Parameters:

object - the object of which this shape is an attribute

asNode - true iff object is a node

origin - the origin of the ray, in local coordinates

direction - the direction of the ray, in local coordinates

transformation - the transformation from local coordinates to world coordinates

list - the list to which intersections have to be added

setPoints

public void setPoints(float[] points)

Make a copy of the points and store it. Points are given by a triple of floats for (x,y,z). The array thus stores points in the form [x0,y0,z0,x1,y1,z1,...].

Parameters:

points - the points to set

setPointSize

public void setPointSize(float value)
