Re: [osg-users] Smooth shading

Hi Geoffroy. If you want smooth shading, why are you setting it to FLAT? sm-setMode( osg::ShadeModel::FLAT ); should read: sm-setMode( osg::ShadeModel::SMOOTH); Hi, I try to add smooth shading to my geometry but for the moment I do not have real success. I use this

Re: [osg-users] how to change project matrix temporarily?;

Hi Shawl, Could you explain for what purpose you need to temporarily modify the projection matrix, this has a huge baring on how you will want to go about it. The OSG has an osg::Projection node that allows you to override the project matrix for the subgraph that you attach below the Projection

Re: [osg-users] Just more 3D primitives

HI Andrey, The OSG's Shape objects original purpose was to provide mathematically defined shapes in support of physics engines. So there isn't an attempt to provide an exhaustive range of different types of shapes, only the ones useful for physics engines. For going beyond this set there is

[osg-users] Streaming world and integer limitations

Hi, I'm thinking about how to do a streaming world in OSG and I have noticed one problem at first. We have scene graph node position - 32 bit integer. We walk through terrain meeting some trees, houses while sectors ahead are loading on a background and then the position of a player and 3d

Re: [osg-users] Smooth shading

Hi, you are right. In the code it is set to flat but I have also tried to set to SMOOTH but I never see difference between results. With the smooth setting I still see the face edges ... Thank you! Cheers, Geoffroy -- Read this topic online here:

Re: [osg-users] Smooth shading

In order to get correct shading results, you have to create correct normals. There is also a smoothing visitor which you could try: osgUtil::SmoothingVisitor sm; model-accept(sm); cheers Sebastian Hi, you are right. In the code it is set to flat but I have also tried

Re: [osg-users] screen capture with Qt

Hi Gianni, I know nothing about your specific implementation, the only thing I can suggest is the general comment is that OpenGL has the concept of current draw and read buffers, when you do a glReadPixels() you should make sure that the read buffer is the same as the scene was rendered to i.e.
