Hi,
I was trying to compile Collada-Dom on Ubuntu.For this i downloaded
collada-dom-2.2.zip and compiled the same as per the instructions given on

for linux.
But when i do make os=linux project=minizip the compiler

same picture in the colladaread example like in my environment. The distance
between the left and right eye images is wrong somehow

Hi Tom,
One wouldn't normally change the viewer's master Camera while the
viewer is running, if you do this you'll been to stop all threading,
assin an Renderer and the get the viewer to rewire the threading.
In you case I would just take the subgraph below your own Camera and
then attach this
Hi Siddhi,
I have never compile Collada-Dom with Cg. Perhaps something has
changed in a recent rev of Collada-Dom. Might I suggest you go visit
the Collada project website for most up to date details on compiling
the DOM and any dependencies.
Robert.

didn't work. They all notify me that:

Hello,
I would like rotate a image. Because I want to rotate the separate images from
my sky box. I think it is difficult to change the texture coordinates of my
sphere. I my idea is to rotate the images at the beginning.
Example
::osg::Image* image = osgDB::readImageFile(c_posX.Filename);
pDevice = alcOpenDevice(NULL);
pContext = alcCreateContext(pDevice, NULL);
alcMakeContextCurrent(pContext);
it work in windows and linux.

Ok, also I have create a sky box like the sky box in the vertexprogramm example

Is it understandable?

Hi Martin,
If you follow the vertexexample closely then then rotation can be simply
added (or removed because its already there) to TexMat in TexMatCallback.
Look at R matrix in TexMatCallback::operator(). Multiply this R matrix by
neccessary rotation. If you don't know what rotation exactly,
so yo have a skybox model (probably a dome). and you want to render
something in cube map and apply that to the skybox, correct?

Thank you for your reply.
How can I download the sources of VRMeer in your site?

Paul,
For HAT, you only need one point. LOS requires a start and end point. Both
require that the points be specified in the database coordinates (i.e.
geocentric Cartesian coordinates for round earth databases).

Robert,
You are right, although vectorbool is slow, it is apparently not the
bottleneck. In my case, the bottleneck was basically, a deep and complex
hierarchy of osg::Switch groups.
I did some frame rate testing, replace all the osg::Switch with osg::Group,
then frame rate tested again.
Hi Tat,
I have been able to run osgOcean by modifying the shaders, but the frame rate
was not acceptable (15 FPS). I have also applied the patch to Texture.cpp, but
it didn't resolve the FBO errors.
Given the framerate is too low, I stop trying to run the software on that
graphics card.

I'm using an osg::Camera to do a render to texture. My setup looks like this

Hello Florian,
Note the attached image. The first chair has no effect, the second chair has
the outline effect, and the third chair has the scribe effect. As you can see

I have a set of nodes in the scene. I implemented an UpdateCallback class and

implementation basically uses the current system time to get the values of

Now the problem. Since

Thanks Robert/Shayne, turns out I was computing HAT correctly but was
using wrong texture filtering ( I store the positions in a texture ).
thus the computed heights were displayed incorrectly in the vert shader.
Thanks again.
