Smart3Dcapture™ Viewer is a visualization software, which allows users to navigate 3D models generated
by the Smart3DCapture™ solution. 3D models are loaded and displayed using S3C level-of-detail ( LOD )
management system, and users can measure distances, pick GPS coordinates, generate animations…

Windows 7 with 4Gb RAM and a video card supporting OpenGL with at least 512 Mb of dedicated memory.
Please download the installation file from the Acute3D website or copy it from the storage unit on which it
was provided to you by Acute3D or one of its authorized resellers.
Select and launch the right file depending on your OS:
 64-bit: S3CViewer-…-x64.msi
 32-bit: S3CViewer-...-x86.msi
Once the Smart3DCapture Viewer module is installed, you can load any file with the
S3C extension by double-clicking it in the Windows Explorer.
The 3D model loads in different tiles and is displayed with a dynamic adaptation of
the level-of-detail depending on the viewing point.

Open the Measurements window ( menu Tools >
Measurements ) to measure distances and positions.
If the model is georeferenced, then GPS coordinates
are shown, as well as altitude, and distances are indicated in meters; otherwise distances and positions will
be relative to the default referential.
Several rendering modes are proposed for a photorealistic model or to highlight the model geometry.
Rendering modes are available in the menu Display > Rendering mode.
Textured mode
Wireframe overlay
Shaded mode

If you encounter any problem installing or using the Smart3DCapture Viewer, please check our FAQ below
or on our website ( updated on a regular basis ) . If you do not find the answer to your question, we invite
you to contact our support team by email at support@acute3D.com.
Question
Answer
How accurate are the 3D measurements?
It depends on the georeferencing accuracy, as well as on the 3D model
accuracy which is linked to the images resolution.
There are artefacts in my model.
Why?
This is most probably due to a lack of data/images when generating the
model. Moving objects, thin parts, reflective or peripheral areas are
known to generate artefacts.
I can ’ t get close enough to the
ground. Why?
A minimum height constraint may be activated in the project to avoid
viewing close ( if the model is not accurate enought for street level
navigation for instance ) .
Under ViewerPro license, Minimum height constraint can be disabled
from the Camera menu.
How to set up the Smart3DCaptu- Stereo display is setup from the Stereo page of the Preferences winre Viewer for my 3D screen?
dow ( Menu Edit > Preferences ) . Select the proper parameters for
your 3D screen and click Ok to go back to the 3D view. Activate Full
screen mode with F12 to hide the user interface.
