[osg-users] Getting animations initial frame bones matrix
Hi, I'm working on a IK system to use in the transition between different animations. I have already implemented the IK CCD algorithm, but I need to know the bones position at animations initial frame. It is posible to get it from osgAnimation::TimelineAnimationManager animation list? or from osg osgAnimation::Animation channels??? I have been looking the osg class reference documentation, but I can't find how to get that information... Any help will be appreciated, Thank you!

Re: [osg-users] Trackballmanipulator and Cameraposition
Hi,
Thank you Nick!
it help a lot.
I found one more tip, so i introduce here.
(im in OSG 2.8.3)
When i put your code outside of while loop, then it didn't work.
Still trackball manipulator ignore assigned camera position.
(I don't know why)
So, i just put the code in while loop.
while(!viewer.done()){
cam-setViewMatrixAsLookAt(camPosition,osg::Vec3(0.0,0.0,0.0),osg::Vec3(0.0,0.0,1.0));
trackball-setByMatrix(osg::Matrix::inverse(cam-getViewMatrix()));
...
Then, it works :D:D
Cheers,
Soonchan

Does cross platform mean you are using Qt framework? In this case just assign a fixed size to the embedding window.

[osg-users] Shader lookup table method: does lookup texture have to be bound to a separate geometry?

Currently I am putting my lookup texture in texturecoordinate 1 of the object I am trying to apply my shader to. The reason I ask is that whenever I try to pull out a value from my lookup texture using a vec2 with values from 0.0-1.0 in my shader and perform any sort of operation using that value, the osg command line spits out: Warning: detected OpenGL error 'invalid operation' at After Renderer::compile -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=45515#45515 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Potential bug in mouse / window event handling
Hello all, I believe that I may have discovered a bug in the GUI abstraction library; although this may be a known issue. Here are the steps to reproduce it. I performed these steps on 64bit Windows 7, as well as 64bit Vista, both using version 3.0.0 built in 32 bit on Visual Studio 2008 sp1. 1. Run osgviewer.exe avatar.osg 2. Press f to switch to a window mode 3. Click and hold both your left and right mouse button and drag towards the edge of the window 4. Release the right button, then exit the window and release the left 5. Move the mouse back over the window WITHOUT clicking any buttons on the mouse 6. You will notice that the trackball is still moving as though the left button was held down 7. Click the left button, the behavior is as expected again To prove to myself that it was probably not the intended functionality, I then performed the following steps 1. Perform steps 1 and 2 above 2. Click the left mouse button and drag towards the edge of the window 3. Drag off of the window 4. Release the left mouse button 5. Move the mouse back over the window WITHOUT clicking any buttons 6. You will notice the trackball is as expected I attached a debugger and went into the event traversal part of the osgViewer::Viewer class and noticed that while the mouse was out of the window (so after step 5 of the first procedure), the event queue still had an event with a mouse button held down. I believe that perhaps, some boundary condition is being hit when there are two buttons and one is released, that is not being handled correctly. I don't have enough time to dig more into this, but I tried to diagnose it as completely as possible given my time constraints. This also impacts the osg mfc example, so it is not limited to the osgviewer application.

[osg-users] How to correct remove objects from scene graph and destruct they not in render thread?
Hi, To remove heavy in destruction objects (which will free large buffers and etc.) I use method like in DatabasePager - hold object references and pass they to another thread for destructing. But there is one case which cause crash. (root) | (some nodes) (...) || (nodeA) (nodeB) \/ \/ (nodeC) | (...) | (nodeD) So we have nodeC with two parents, and in some moment we want to delete subgraph with nodeA. We remove from graph parents of nodeA and hold it reference to be destructed later in another thread. Another thread decrease reference for parents of nodeA and initialize destruction, so nodeA have no more references and it want to be deleted, it inform children about that and request to remove it from parent list. But in render thread we still render main graph and it traverse nodeC, but someone like nodeD changed it's matrix, this process require to dirtyBound, and dirtyBound inform all parents about this and tries to walk backward for all parents and nodeA too. So one thread iterate _parent vector, second thread change this vector, and in result CRASH! Looks like DatabasePager affects this problem too. What you can advice in this case?
