3.3.2 Viewing Data

SceneVision can be used as a simple but powerful tool for viewing the types of data described
earlier. It efficiently displays range data, photo data and model data with a consistent user
interface and a wide variety of analysis tools. SceneVision provides a variety of display options
to get different insights from the same data. These tools are available immediately after
scanning, or can be used later to review data when necessary. Section 7 describes SceneVision's
view functions.

3.3.3 Processing Scan Data

SceneVision can be used to process the initial scanned data in a number of ways, making the
data more useful.
Range Alignment
Capturing a complete scene often will require scans from more than one location, for example,
to capture all sides of a piece of furniture or some other 'hidden' part of a room. SceneVision
provides tools for combining these scans to create a complete model by aligning them to each
other. (See section 9.) This is called range alignment.
Once scans are aligned you can measure the distance from a point in one scan to a point in
another. You can also produce a complete 3D model from all or part of the aligned scans.
Color Alignment
Color alignment is used to 'map' digital photos to range data – producing color range data. This
color range data can then be used to create color 3D models. SceneVision provides the tools for
color alignment. (See section 10.)
Model Creation and Editing
SceneVision provides the tools for producing 3D VRML models from a single scan, or from
multiple aligned scans, with or without color. (See section 11.) A new feature in SceneVision
version 3.1 is model simplification. This enables reduction in the size of a model (the number of
triangles in the model) while maintaining high visual quality and accuracy. There are additional
tools with which you can edit these models, to eliminate overlapping sections, and you can
integrate close-up photos enhancing the realism of parts of a scene. (See section 12.)

3.3.4 Data Analysis and Annotation

SceneVision provides a variety of tools for annotation and analysis of range, photo and 3D
model data including:
DeltaSphere-3000 3D Scene Digitizer
Measurement
Drawing
Adding labels, captions, and text annotations
Attaching close-up photos
