IBM Lotus Symphony


Setting 3D view properties

For a 3D chart you can set perspective, appearance and illumination.

To access this command...

Select Layout > 3D View

Perspective

Set all angles to 0 for a front view of the chart. Pie charts and donut charts are shown as circles.

With Right-angled axes enabled, you can rotate the chart contents only in X and Y direction, that is, parallel to the chart borders.

An x value of 90, with y and z set to 0, provides a view from top down to the chart. With x set to -90, you see the bottom of the chart.

The rotations are applied in the order first x, then y, last z.

When shading is enabled and you rotate a chart, the lights are rotated as if they are fixed to the chart.

Note Icon The rotation axes always relate to the page, not to the chart's axes. This is different from some other chart programs.

Select the Perspective check box to view the chart in central perspective as through a camera lens instead of using a parallel projection.

Set the focus length with the spin button. 100% gives a perspective view where a far edge in the chart looks approximately half as big as a near edge.

Note Icon Older versions of Lotus® Symphony™ cannot display the percentage of perspective the same way as the current version.

Appearance

By selecting a scheme, the check boxes and the light sources are set accordingly.

Illumination

Set the light sources for the 3D view.

  1. Click any of the eight buttons to switch a directed light source on or off.

    By default, the second light source is switched on. It is the first of seven "normal", uniform light sources. The light source number one projects a specular light with highlights.

  2. For the selected light source, you can then choose a color and intensity in the list box just below the eight buttons. The brightness values of all lights are added, so use dark colors when you enable multiple lights.

  3. The small preview inside this tab page has two sliders to set the vertical and horizontal position of the selected light source. The light source always aims to the middle of the object.

  4. The button in the corner of the small preview switches the internal illumination model between a sphere and a cube.

  5. Use the Ambient light list box to define the ambient light which shines with a uniform intensity from all directions.
