Usage

From source file:ExSpotLight.java

public AnnotationLine(float x, float y, float z, float x2, float y2, float z2) {
    float[] coord = new float[3];
    float[] texcoord = new float[2];

    // Build a shape
    shape = new Shape3D();
    shape.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);

    // Create geometry for a 2-vertex straight line
    line = new LineArray(2, GeometryArray.COORDINATES | GeometryArray.TEXTURE_COORDINATE_2);
    line.setCapability(GeometryArray.ALLOW_COLOR_WRITE);

    // Starting point
    coord[0] = x;//from w ww. j  av a2  s .c  o  m
    coord[1] = y;
    coord[2] = z;
    texcoord[0] = 0.0f;
    texcoord[1] = 0.0f;
    line.setCoordinate(0, coord);
    line.setTextureCoordinate(0, texcoord);

    // Ending point
    coord[0] = x2;
    coord[1] = y2;
    coord[2] = z2;
    texcoord[0] = 1.0f;
    texcoord[1] = 0.0f;
    line.setCoordinate(1, coord);
    line.setTextureCoordinate(1, texcoord);

    shape.setGeometry(line);

    // Create an appearance
    mainAppearance = new Appearance();
    mainAppearance.setCapability(Appearance.ALLOW_LINE_ATTRIBUTES_WRITE);
    mainAppearance.setCapability(Appearance.ALLOW_COLORING_ATTRIBUTES_WRITE);

    lineAttributes = new LineAttributes();
    lineAttributes.setLineWidth(lineWidth);
    mainAppearance.setLineAttributes(lineAttributes);

    coloringAttributes = new ColoringAttributes();
    coloringAttributes.setColor(lineColor);
    coloringAttributes.setShadeModel(ColoringAttributes.SHADE_FLAT);
    mainAppearance.setColoringAttributes(coloringAttributes);

    addChild(shape);
}
