Hi Frie,
osg::ShapeDrawable was never intended with this type of usage, it's just a
convenience for the occasional visualization the shape primitives.
osg::Geometry is the class intended for general usage in the scene graph
and is designed around OpenGL fast paths so you can achieve the better

Hi Sonya,
I'm not sure, but I guess the result simply contains all vertices
contained. So you will have to filter the results yourself or check the
interface for options to configure the results filtering.

Hi,
osg can read S3TC images. I think you have to do osgviewer --image
myfile.dds. Do osgviewer --help you will see the correct option

Hi, Trajce,
I am on vacations. Quick answer is impossible in my opinion. I would bet
that projection software uses some matrix tricks and it would be hard to
figure it out without seeing the code and solution. There is a chance
though, that matrix obtained there is not a right projection matrix
strange. I did osgviewer --image sample.dds and it works just fine.
Attached is a screenshot. is there any message on the console? Can you
locate osgdb_dds.dll (you on windows??? or linux)? is your osg bin folder
in your PATH?

Hi Wojtek,
thanks for the fast reply. I am going to investigate this but there is no
source code (black box) so it is hard to say. I took very naive approach
for the moment since I am not familiar with the code of the
MinimalShadowMap that much and will try to force the conditions in the

Thank you for the entrypoint,
What you mean by rescaling the geomtry directly? Directly modify the vertices
and dirty the displaylist, rather than using transformation matrices? I'll try
that workaround, it sounds quite coherent for the reason of discrepancy.

Hello Robert,
Yes, you are right. The reason is that I didn't set up the texture coordinates.
I did the following change, and I could texturing the model in the shader. I
think the problem is that gl_MultiTexCoord0 actually didn't give out any
texture coordinates in my first code.

Hi Ying,
The cow.osg model uses osg::TexGen (wrapper for glTexGen) to generate the
texture coordinates so the ones assigned to actual geometry are ignored.
glTexGen is part of the fixed function pipeline in OpenGL so you don't get
this functionality when using shaders. You'll have to implement

I read the code of MinimalShadowMap and tried to understand it (at least

some result. The best results I have got is that the shadows are now still
