How to : Use Screen Capture

Using screen capture in Present3D to save images and make movies.


This is a test volume render in Present3D using a Colour Look Up Table to hide and colour selected parts of the CT data. The movie was created using Present3D's save to image sequence feature and then opened in Quicktime Pro 7 to convert to a movie. Three sequences were saved then combined in Motion. The final zoom sequence used a path in Present3D to create the zoom.

Single Image :

To capture a single image press the "m" key and an image will be saved to the same directory/folder where your presentation xml file is located. If you want to change the location where files will be saved you can do this by starting your presentation using the following additional command  : 

--screenshot folder_name/filename.jpg

Installing Present3D on OSX

Page still in process of being written.. still..

Installing from Binary :

At this time (Dec 2010), there isn't an up to date binary available, but as soon as there is, it will be available for download from here.

Building from Source :

Present3D is now part of the OpenSceneGraph source so a download of the code from the SVN repository will get the most up to date code, but before you do that you need to make sure you already have the following :

1)  Developer Tools :

If installed you will have a folder called Developer which has Xcode 3.x.x application, if not then you can either install from your system disk or download from the Apple site.

2) Cmake :

The OSG currently uses Cmake to generate either make  files or an Xcode project depending on your preference.

Cmake can be downloaded from here : http://www.cmake.org/cmake/resources/software.html

You want the Mac OSX Unversal .dmg

Present3D now supports CLUT with DICOM Volumes!

As part of the ongoing Joint Medical Visualisation Project with Aberdeen University, Present3D has now been updated to use Hounsfield Units and allow Colour Look Up Tables (CLUT) to be used. A full version of the above clip in side x side stereo can be downloaded from here:

More information about this project can be found here:

Stereo Movies available to download :

This is a short clip from a side x side stereo movie created with Present3D from a dicom series of CT slices.

A number of full screen stereo movies are available to be downloaded here :


Low Cost Stereo Visualisation

 Low Cost Stereo Visualisation for Higher Education:

Over the last few years Phil Lavery has been doing a series of events and seminars to introduce low cost, easy to use, but very powerful Real time Interactive 3D Stereoscopic Visualisation to Higher Education and Research Institutions.
