Vaisala IRIS - Volume Rendering; Figure 108 Example of Surface Rendering

IRIS 3DView allows up to 4 of these iso-surfaces to be drawn in the same 3D visualization.
The threshold value, color and opacity of each surface is user configurable. This allows a
flexible representation of the radar data.
Proper opacity control of the surfaces is important for good visualization. The more opaque
a surface is (higher opacity value), the more dicult it is to see through. The less opaque,
the more transparent the surface becomes and it is easier to see through it.

Volume Rendering
In volume rendering mode, IRIS 3DView renders a 3D visualization of the data that is
between the minimum and maximum values. All other data outside this range is filtered out
and not displayed. Instead of using distinct surfaces, the area is rendered so that it gradually
changes from the color and opacity at the minimum value to the color and opacity at the
maximum value.
The minimum and maximum values, as well as the color and opacity at the ends of this
range, are user configurable.
