3D Output
Options
These menu options
are used to select the output (file) resolution
for the 3D scanned image
data. The finer the resolution the larger the output file will be. The
method used is by sampling every n-number of pixels where n is the option of full
(1 or every pixel), fine (every 5 pixels), medium (every 10 pixels) and user selectable
from 1 to 255.
Resolution:
Choices are 1, 2, 4, 8 - This determines the sample size or the number of steps
between digitizing. Eg. 4 (the default) will read every 4th pixel, 1 will
read every pixel (maximum resolution). If the image is small, resolution
of 1-2 would be reasonable, if the image is large then 4 or 8 may be best. The
higher the resolution the larger the data set that will be created, especially
if saving the full color data.
Output type:
Grey
- this option will generate
a file with 3 columns of data, x, y, z(intensity)
RGB(color)
- this option will generate a file with 5 columns of data, x, y, r(ed), g(reen),
b(lue). As you can see using fine resolution with RGB selected can produce
a file of many megabytes. For most purposes a sample of every 2 or more
is sufficient resolution.

Balance
:
These apply to color images only in that to create an intensity (grey) level (for
x, y, z only output) it is necessary to combine the 3 primary colors (RGB) in
one of two ways.
Weighted
- this applies a weight
to each of the three colors based on the eye's sensitivity
to each specific color based
on standard algorithms.
Averaged
- the three levels from
red, green and blue are averaged together (sum/3) to generate an intensity for
the z axis.
