[osg-users] Request for assistance to embark into PhD
Hello, Being a software engineer, I did my final project study in 3D animation and virtual reality visualization using OpenSceneGraph. Today I want to prepare my thesis in augmented reality. I'm looking for a good topic to prepare in 3 years. What are the themes of current research linking OpenSceneGraph and augmented reality? can you suggest me some possible topics ... for my future thesis? Thank you in advance !

Re: [osg-users] Request for assistance to embark into PhD
Hi, Very good point, you are right. OSG is a technology , I have to see it as a tool in my research. Where can I find an open AR problem ? where am I supposed to look ? How to do that ? ps: I found a thesis director, I will speak to him later today. Thank you!

[osg-users] “Include can't be =?UTF-8?Q?found=E2=80=9D?=, how to fix it?
Hi, I am developing using OpenSceneGraph. I installed it from a user-runnable installer (http://www.artoolworks.com/dist/openscenegraph/3.1.x/). When I try to compile an application using OpenSceneGraph, I have this Include can't be found for all osg/* includes, like osg/AnimationPath. The file is available here /Library/Frameworks/osg.framework/Versions/92/Headers/ So following this solution on how to add existing frameworks to the new Xcode (http://stackoverflow.com/questions/3352664/how-to-add-existing-frameworks-in-xcode-4). I added osg.framework to the project : [Image: http://i.stack.imgur.com/EUl3V.png ] any idea is a welcome.

Re: [osg-users] Is it safe/ok to use only PositionAttitudeTransforms instead of MatrixTransforms
Hi, If you are articulating some objects, like Robot arm, you rather use MT. for instance a rotation of a joint imply rotation of the rest of the arm, rather then computing the Position of each part , you construct a hierarchy of MTs and Multiplying one MT by another apply the change on the rest of the part ... I advice you to make a look at OpenSceneGraph Example osgRobot.

Re: [osg-users] Is it safe/ok to use only PositionAttitudeTransforms instead of MatrixTransforms
Hi nerazzuri,
[quote=nerazzuri]But isn't this the same behavior as having a chain of PATs
where modifying one transform node's position/attitude affects all the nodes
downstream? [/quote]
the same functionnality but you will have to specify a value rather then
multiplying.
[quote=nerazzuri]Are you implying that it is easier to apply rotations to a
series of MT than it is to a similar PAT hierarchy?
[/quote]It is not question of easier or not. First, it depends on the context,
both PositionAttitudeTransform MatrixTransform can do the same stuffs. Except
that, when you use a PAT, you are, kind of setting, values {_position,
_attitude, _scale, _pivotPoint}. On the other hand, MT encapsulates a Matrix
and using preMult or postMult will implicitly do the job for you.
It is by practice and intuition, you figure out the right Transform to use.
Maybe I can help more if you tell me more details on how you want to use them.
Cheers
Mohamed ALJI
