begins. Creating simplified models of multiple 360 degree scans will take several hours and, in
general, the computer will be fully occupied with this task and too slow for other work.
After creating simplified models, you can use the functions described in the previous two
sections to combine them into a single model. The next section describes how to edit these
combined models.

Editing
SceneVision provides a number of functions for simple editing of data sets. For example, with
SceneVision you can delete parts of a scan that overlap another scan. This can result in a
simpler 3D model. You can also fill in planar regions where data was not collected because the
surface was too shiny or too dark to scan with the laser. SceneVision is not a modeling package.
For extensive data editing there are many different packages compatible with DeltaSphere data.
Please contact 3rdTech for additional information.
12.1
Model Editing
As described in Section 11, models are typically created from multiple scans. These scans will
always have overlapping regions – necessary for aligning scans and combining them into a
single model. It is often desirable to keep the overlapping region from one scan – one with a
better view, perhaps – and delete the region from another scan. You can accomplish this by
selecting parts of different aligned models which do not overlap and combine\ing them, or you
can combine the complete models and then delete some of the overlapping parts. SceneVision
has a simple Model Editor function that helps with the second approach.
Begin with a model created from more than one scan (clue.wrl in the sample data). With the
model displayed, right click on the model file in the scene tree and select
Edit Model
. The
Model Editor window shown in Figure 57 will appear.
