[osg-users] VirtualPlanetBuilder database and rotations for view matrix
Hi everyone, I am working on a little toy flight sim type program using the blue marble data with virtual planet builder, built with --geocentric in wgs84. I have managed to integrate some basic physics, and I set up an eye-point above the vehicle facing down with north always up in my view. I want to have a mode where the view is actually at the eyepoint of the aircraft and matches its rotations. This is where I am having problems... The data I have are the euler angles and position (xyx). I've tried a number of approachesto manually set the viewmatrix, but so far, I haven't had much luck. I'll outline what i have tried below. At first I tried using a make look at, but I couldn't figure out what the parameters other than eye should be, so I moved on to setting up the matrix myself. First I tried building the rotation matrix by setting it like you would the model matrix, but I realized that it should actually be the inverse of that. I then tried taking the rotation matrix of the aircraft and the translation of the aircraft, and applying them like they do in flightgear, which is : double phi, theta, psi; // given in radians osg::Vec3d position ( x, y, z ); // gcc meters osg::Quat Qeul = makeEulerQuat( phi, theta, psi ); // same function used for drawing the model which works... osg::Matrixd viewMatrix ( osg::Matrixd::translate( -position ) * osg::Matrixd::rotate( Qeul.inverse() ) ); getCamera()-setViewMatrix(viewMatrix); I'm stuck on this one, I haven't been able to get the camera to look correct in any orientation other than top down (because I know how to set up makelookat for that ;)). This must be a fairly common problem, perhaps there is an FAQ or an example I missed that spells it out. Anyone have any idea what I am doing wrong?

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
I can say that I am 100% sure that you do not need a Geforce card, or actually any video card at all, to write and use programs that are built on the PhysX SDK. You would only need a Geforce card if you decided to use hardware acceleration, which currently only works for fluids and cloths. So basically, for what you are doing you cant even utilize a Geforce card with the current version 2.8.x of PhysX. Regards, ~Mike B.

Anyway, if you wish an engine and don't know which one to choose, you can always try PAL (Physics Abstraction Layer), which works with ODE, Bullet, PhysX, and more ( http://www.adrianboeing.com/pal/ and http://sourceforge.net/projects/pal ).

I guess no) And if you wish to have something that doesn't hide OSG, and that is much simpler than Delta3D, then you may look at what I did in PVLE ( http://pvle.sourceforge.net ). For the moment, I must admit ODE is a bit hidden in PVLE, but I'm currently modifying it so it also shows ODE as it does for OSG. There are many other implementations that can bind physics and OSG (see osgPhysics too... but it's not finished yet), but if you wish something simple, then PVLE may suit your needs.

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
Ümit Uzun, Modeling dynamic entities in physics is quite different from the visual model that you are accustomed to. Personally, I would create your physical model of your jeep and your world in physics, and allow physics to determine the intersects. Your visual world will, probably, contain much more detail than will be required in your physics world. For instance, plants on the ground will need to be drawn in the visual, but will not appear in the physics database unless required. In short, let physics do the collision detection for physics, keep your physics entities and databases as sparse as possible and you will get the best performance. Also, just because I am curious, did you look at bullet physics or nVidia PhysX?

Re: [osg-users] Any suggestion about OSG-ODE integration and collision detection.
One more thing, if you do your collision detection in OSG, you will need to handle the physical response yourself. The physics engine is already set up to handle that correctly. For starters, i'd just stick with physics.

The FLTK developers are working more on their 1.3.x branch, which adds UTF8 and (at least until recently) a tree browser widget. I would love to have the browser widget for my application because I'm using an unsupported one from a third party at present, so eventually I may move to 1.3.x, but even that is not yet API -stable. Originally I was also using FLTK 2 because of the built-in tree browser widget and the fltk namespace, but it did not ever work well with my application on the Mac, so I started over with FLTK 1.1.x.

Re: [osg-users] Attaching Nodes (Characters Objects)
You could use a callback on the transform from the hand to update the transform on the other node. The other way is to position the other node under the hand in the hierarchy. The transforms of the other node then become relative to the hand. You'd need to convert local to world in order to do updates in the world frame but your goal of co-movement would be achieved.

Re: [osg-users] SDL osgViewer
You can do along the lines of what Delta3D has done, by using http://plib.sourceforge.net/ as a source of your data and interfacing it into OSGGA.

There is an osgviewerSDL in the examples (v2.3.4) but this is for an embedded OSG viewer inside an SDL window... would those work with a joystick ? You can subclass from osgGA::GUIEventAdapter and add your joistick-data to it and feed it to the current event queue. In your eventhandler you can dynamic_cast to your subclassed Event-Adapter and read the joystick-data and handle it accordingly. I am using this technique to feed the events from a SpaceNavigaor to a custom event-handler. Or you encapsulate you joystick-data into a custom class and attach via setUserData to a GuiEventAdapter and push it with type USER to the eventqueue, and handling it in your event-handler. You can even mimick a mouse by feeding the event-queue with fake mouse-events from your joystick-data.

Re: [osg-users] How to work with Delta3d in MFC SDI ?
What version of Delta3d are you using? Also, this question may be better
suited for the Delta3d forums http://www.delta3d.org/forum/index.php

Hi, all,
In OSGViewerMFC MDI or SDI, it begin a thread in OnInitialUpdate() of
MFC_View:
* mThreadHandle = (HANDLE)_beginthread(COSG::Render, 0, mOSG) ,*
and in *Render(void* ptr)* function, it likes this:
* while(!viewer-done())
{
osg-PreFrameUpdate();
viewer-frame();
osg-PostFrameUpdate();
}*
**
Well, if i do it with Delta3d in MFC SDI, how to put the Delta3d's
function corresponding to make it work like that ?
I had a try with dtABC::Widget refered to the example testWidget, then i
made it like this :
1. class MyWidget : public dtABC::Widget
2. void MyWidget::InitWinData(HWND hwnd, int x, int y, int w, int h)
{
dtABC::WinData windata( hwnd, x, y, w, h );
SendMessage( dtABC::Widget::msgWindowData, windata );
SendMessage( setpath, path );
SendMessage( loadfile, m_ModelFile );
}
3. void MyWidget::Render(void* ptr)
{
// I don't konw witch function i should put here!
}
4.void CD3DMFCView::OnInitialUpdate()
{
CView::OnInitialUpdate();
m_MyViewWidget-InitWinData();
// Here, should i begin a thread like OSGViewerMFC does in its
OnInitialUpdate() ?
// m_ThreadHandle = (HANDLE)_beginthread(MyWidget::Render, 0,
m_MyViewWidget);
}
Thank you indeed for your patient
Best regardes !!!
