Analyzing Lighting Statistics
You can obtain statistical data such as averages,
minimum and maximum values, and criteria ratings
to evaluate luminance or illuminance for a specific
surface or a point on a surface.
Displaying Light Energy Statistics
Display light energy statistics based on either lumi-
nance or illuminance values.
To show light energy values for a surface:
1.
Choose Light | Analysis.
The Lighting Analysis dialog appears.
2.
Click the Display tab.
3.
Select an item from the Quantity list.
4.
Click the Statistics tab.
5. Click a point on a surface in the model.
The selected point appears on the surface and the
surface is highlighted.
Information related to that point and the surface is
displayed on the Statistics panel.
6.
To view information for a different point on a
surface, click that point on the surface of the model.
Analyzing Light Energy Statistics
Each time you select a point on a surface of your
model, statistical information about the point and
the surface is displayed on the Statistics panel. The
following information is available:
• Point
• Average
• Max and Min
• Avg Min, Max and Min, and Max Avg.
Point
Displays the luminance or illuminance value at a
selected point on a surface. The X, Y, and Z coordi-
nates of the point also appear in parenthesis.
Average
Displays the average value of the target quantity over
the selected surface.
The average value is a simple way of characterizing
the performance of a lighting system when the shape
of the distribution of light over the surface is fairly
simple.
