This project allow users to use the android device (as a client) to connect with CalVR (as a server) by the TCP protocol, then they can move any object and interact with it in the virtual world by using the android device. It allow users to move objects on the CalVR by using any kind of mode such as Move World, Scale, Drive and Fly, and then see the object movement changes on the android device. Also, they can use the android device (client side) to move the camera around the object to see the object from all sides. Finally, they can use the android device (client side) for picking objects to receive pictures about this object. They can use all these techniques with Artifact Archeology project to interact with the historical objects in the real world. Also they can use this plug-in with other projects.

Usage Instructions

Server
- This is the path to find the server code /home/saseeri/CVRPlugins/calit2/MagicLens
- IP Address: Use this command line to find the IP address ifconfig
- Use this PORT 28888
- We can find objects on /home/saseeri/Development/OpenSceneGraph-Data folder

Client
- This is the path to find the client code /home/saseeri/CVRPlugins/calit2/MagicLens, the name of the folder OSGTest1-AndroidClient
- IP Address: Use the same IP address on the server side and put it on the code
- Use this PORT 28888
- Use the same object that is used in server side and put the object on the android memory card and wrtie this path on the code /mnt/sdcard/create_any_file name/object_name

To compile and run the code do the following:

Start with the server

Go to this path on the terminal /home/saseeri/CVRPlugins/calit2/MagicLens

Write on the terminal

  make
  ...  
  CalVR

After that, Copy the client code to the eclips workspase and do compile to the Android ndk (C++) by using the following:

Go to this path on the terminal /home/saseeri/workspace/OSGTest1-AndroidClient

Write on the terminal

  ndk-build

Then go to the eclipse right click on the project then run it after you connect the android device

Click on Start Client
Then Connect Server

Screen Shots

We can translate the object from the android device by touch screen

Also, we can rotate the object from the android device

What is done so far ...

load model into Android Device and CalVR with osg
Connect the Android Device and CalVR over wifi (by using TCP protocol)
Move objects on the CalVR by using any kind of mode such as Move World, Scale, Drive and Fly, and then see the object movement changes on the android device

Future Work

+===Developers===
-'''First: OpenSceneGraph'''
+'''Software Developer'''
+* Sahar Aseeri
-The resources that I used to learn OSG
+'''Project Advisor'''
+*Jurgen schulze
-"OpenSceneGraph 3.0 Beginner's Guide book" and the OpenSceneGraph website.
-I read the following chapters:
-'''Chapter 1:''' The Journey into OpenSceneGraph
-'''Chapter 3:''' Creating Your First OSG Program
-'''Chapter 4:''' Building Geometry Models
-'''Chapter 5:''' Managing Scene Graph
-'''Chapter 6:''' Creating Realistic Rendering Effects
-'''Chapter 9:''' Interacting with Outside Elements
-And some tutorial related to the following topics:
-* Geometry
-* 2D Text write function to set camera position in osg from head node: for
-testing, transfer 4x4 matrix of head pos
-* Transformation (Translation, Rotation, Scaling)
-* Shapes (Box, Cone, Sphere, Capsule, Cylinder)
-* Polygon mode
-* 2D Texture (load image from images file)
-* Interaction with outside element (keyboard and mouse)
-I read the previous topics and ran them on my PC and made some changes to the code to understand what each method does in the code.
-'''Second: CalVR
-'''
-I read the CalVR website, and I will focus on it more on Monday
-'''Third: Android'''
-I started with android: installed it on my laptop, done the "Hello World" program and ran it in my android devise. I also read about the following topics:
-* Camera
-* Kind of sensor
-* Activity
-* Create list, buttons
-'''roadblocks I have encountered:'''
-* Working with OSG installation
-* Write a makefile
-* Working with some linux commands.
-* Understanding CalVR (but I did not give CalVR much time to work on)
-* There were no simple Examples for OSG on the internet so I used the book "OpenSceneGraph 3.0 Beginner's Guide book" to practice some simple examples.
-* I couldn't understand some mathematical equations in your slides.
-'''Summery'''
-Look for tutorials on OSG and compile them on your PC in my lab	          '''Done'''
-Creating boxes and spheres					          '''Done'''
-Displaying images from JPEG files				          '''Done''' (I used the image as texture)
-Mouse control: move/rotate objects in 3D                     	          '''Done''' (move/rotate objects in 3D and Picking objects)
-Understand the concept of a scene graph				          '''Done'''
-Go through the slides on this web site 				          '''Done''' (Lecture 1, 2, 3, 4, 5, 6, 10) I read in general and will continue reading
-====Week 3====
-Reading and understanding the code (Done 60%)
-Read about socket programming (Done without any practical code)
-====Week 4====
-Install OSG on the Android device  (Motorola Xoom tablet)  '''Done'''    But it's doesn't work
-Load any Object and I apply rotation, translation, and scaling it by touch screen   '''Done'''
-====Week 5====
-Continu install OSG on the Android device but on the Galaxy mobile  ''Done'''
-Load any Object and I apply rotation, translation, and scaling it by touch screen   '''Done'''
-load excavation site model (osg file) into mobile with OSG       '''Done'''    But the output is a black screen
-====Week 6====
-osg::MatrixTransform * getObjectTransform () returns the position of the data set in room coordinates; send this to phone; on phone, put it in a MatrixTransform just above the node with the cow
-===TODO===
-* load excavation site model (VRML file) into tablet with osg:
-** osg::MatrixTransform * getObjectTransform () returns the position of the data set in room coordinates; send this to phone; on phone, put it in a MatrixTransform just above the node with the cow
-** Goal: when flying around data set in CalVR, the view on the phone should change accordingly
-** getHeadMat() returns the head position in room coordinates: this is constant at a desktop, but changes in the caves
-- write function to set camera position in osg from head node: for
-testing, transfer 4x4 matrix of head position over wifi to tablet:
-this will effectively copy the view on the Calvr system to the tablet
-- sense touch on artifact, then send touched artifact ID to Calvr
-computer, which will send associated photograph to tablet; display
-photograph on tablet. This will allow the user to view pictures
-associated with artifacts on the screen
-- connect tracking system to tablet to allow moving tablet around
-starcave and view excavation site model from arbitrary perspectives on
-tablet screen.
