Usage

From source file:MixedTest.java

public void renderField(int fieldDesc) {
    super.renderField(fieldDesc);

    GraphicsContext3D g = getGraphicsContext3D();

    // first time initialization
    if (m_nRender == 0) {
        // set the start time
        m_StartTime = System.currentTimeMillis();

        // add a light to the graphics context
        DirectionalLight light = new DirectionalLight();
        light.setEnable(true);/*from ww w  . ja  v a2  s  .  c o  m*/
        g.addLight((Light) light);

        // create the material for the points
        Appearance a = new Appearance();
        Material mat = new Material();
        mat.setLightingEnable(true);
        mat.setAmbientColor(0.5f, 1.0f, 1.0f);
        a.setMaterial(mat);
        a.setColoringAttributes(new ColoringAttributes(1.0f, 0.5f, 0.5f, ColoringAttributes.NICEST));

        // enlarge the points
        a.setPointAttributes(new PointAttributes(4, true));

        // make the appearance current in the graphics context
        g.setAppearance(a);
    }

    // set the current transformation for the graphics context
    g.setModelTransform(m_t3d);

    // finally render the PointArray
    g.draw(m_PointArray);

    // calculate and display the Frames Per Second for the
    // Immediate Mode rendering of the PointArray
    m_nRender++;

    if ((m_nRender % m_kReportInterval) == 0) {
        float fps = (float) 1000.0f / ((System.currentTimeMillis() - m_StartTime) / (float) m_kReportInterval);
        System.out.println("FPS:\t" + fps);

        m_StartTime = System.currentTimeMillis();
    }
}
