GWT Augmented Reality - HOWTO - step 2

Welcome to the third (and fortunately last) step of using NyARToolkit in a GWT project.

In the previous steps (step 0 and step 1) we got NyARToolkit ready for our GWT project and we
used  the toolkit to detect a marker on a static image; now we are going use the stream from the webcam to populate the sensor.

First of all we should now really switch to GWT 2.5 and Elemental; quoting form the first post of the series:

Using Elemental in a GWT project is quite straightforward:

1. donwload the latest GWT (well, we used for this project RC1 but all seems safe to be done with 2.5.0 final) and setup a new project;
2. add to the build path gwt-elemental.jar (is in the unpacked gwt 2.5 archive);
3. add to the gwt.xml file the line  <inherits name='elemental.Elemental'/>
   ....

and we are ready.

GWT Augmented Reality - HOWTO - step 1

Welcome to the second step of using NyARToolkit in a GWT project.

NOTE:
At the end of the previous step we used the super-source tag; someone may have noticed that when you use super-source you end up with an eclipse project with errors: the project compiles with GWT and works without problems but eclipse signals errors in all the super-source'd classes (actually because package names are not correct).
To find the best solution for this annoying situation, last week I asked on the  google-web-toolkit google group. Actually the full solution is harder than we can afford in this post but you can find here the thread; in our demo-project without serverside component and without tests the first response in the thread is enough, but for a bigger application some care is needed.

GWT Augmented Reality - HOWTO - step 0

This post is the first of a short (we hope) series describing the steps required to use NyARToolkit in a GWT/Elemental project.

The sample is at http://www.jooink.com/experiments/ARtest1/ (use chrome !!)

Augmented Reality using WebRTC, NyARToolkit, GWT, Elemental, WebGL --- Test 0

What an intense coding day today but finally we had the first working-test :)

               

[Demo HERE, use latest chrome]

Only GWT 2.5/Elemental, no plugins are required. 

Based on NyArToolkit, using WebGL for 3D rendering and WebRTC to access the camera this shows why GWT is a booster :). 
Thanks Google !!
