public class Line

extends Geometry

Line subclasses geometry and defines a collection of lines. For each two points, a line is created. The last point of the previous line is the first point of the next line. Therefore, for N points there are N-1 lines.

Constructor Detail

Line

public Line(java.lang.String name)

Constructs a new line with the given name. By default, the line has no information.

Parameters:

name - The name of the line.

Line

public Line(java.lang.String name,
            Vector3f[] vertex,
            Vector3f[] normal,
            ColorRGBA[] color,
            Vector2f[] texture)

Constructor instantiates a new Line object with a given set of data. Any data can be null except for the vertex list. If vertices are null an exception will be thrown.

Parameters:

name - the name of the scene element. This is required for identification and comparision purposes.

vertex - the vertices that make up the lines.

normal - the normals of the lines.

color - the color of each point of the lines.

texture - the texture coordinates of the lines.

Method Detail

draw

public void draw(Renderer r)

draw calls super to set the render state then calls the renderer to display the collection of lines.

Overrides:

draw in class Geometry

Parameters:

r - the renderer used to display the lines.

See Also:

Spatial.draw(com.jme.renderer.Renderer)

drawBounds

public void drawBounds(Renderer r)

drawBounds calls super to set the render state then passes itself to the renderer.

Overrides:

drawBounds in class Geometry

Parameters:

r - the renderer to display

findCollisions

public void findCollisions(Spatial scene,
                           CollisionResults results)

Description copied from class: Spatial

checks this spatial against a second spatial, any collisions are stored in the results object.

Specified by:

findCollisions in class Spatial

Parameters:

scene - the scene to test against.

results - the results of the collisions.

hasCollision

public boolean hasCollision(Spatial scene,
                            boolean checkTriangles)

Specified by:

hasCollision in class Spatial
