I respond to myself: Removing the model skeleton, and therefore the animation
manager, I can see the morphing on the model...
Is there any way to combine skeletal osgAnimation and manual vertex edition to
do morphin myselft? I dont want to use osg morphing system...
Thank you!
Cheers,
Aitor
Hi Aitor,
The same issue you face, is there as well with the default morphing and
skinning of osgAnimation. You need to do this steps to make it work.
First Create your custom morph geometry, add it to a geode, add the
geode to a group ( groupMorph ) and attach this somwhere to the
scengraph,
Hi,
I'm facing the same problem...
Have you found a solution ?
Thank you!

dcmtk source code 3.6.0 from http://dicom.offis.de/dcmtk.
First i have compiled dcmtk ... all ok.
Then, i get no error from compiling of ReaderWriterDICOM.cpp in Plugins dicom.

Hi Andrea,
DCMTK changed after the release of OSG-2.8.x which caused the build break.
OSG-3.0.x and svn/trunk both with with the latest DCMTK so please
update to a recent version of the OSG.

I try to write information of other things rather than that of color

However, whatever value I set gl_color.a(the fourth element above)

Hi Shuiying,
You will need to use an RGBA colour buffer, so make sure your are
creating a graphics context with a alpha value of 8 set. See
osgcamera example for an example of manually setting up the graphics
context.

Hi All,
I would like to set a color to a node that comes from an obj file (attached).
Here is the code I tried. You can simply use it in whatever OSG example.
Code:
osg::ref_ptrosg::Group root = new osg::Group;
osg::ref_ptrosg::Node scene = osgDB::readNodeFile(wheel.obj);
if (scene.valid())
{
It seems the first obj file has not been added to the previous message ...

Hi Robert,
thank you for your reply.
I was hoping to build the plugin with osg 2.8.2 for compatibility with other
modules.
But, if there are no way to compile, i'm forced to do that.
Thank you again.

I will do a first test in this way. As soon as I can, I will move to the new

following strategy:
Create a drawable for the cylinder's back faces first by relying on
GL_CULL_FACE using a specific winding order
of the quads to only render the rear wall. Add this drawable to the Geode first.

You might want to look at the osgdepthpeeling and/or the osgoit examples.

I think I figured it out. When it links my program for some reason it uses the
names InstancePositions[0] and InstanceScales[0] when it builds its
_uniformInfoMap in the function linkeProgram(). It obtains the names of the

This has been discussed extensively recently, but I don't recall the

then you might try posting a new thread (as it has nothing to do with

It might already be fixed on trunk, so if
