Open Scene Graph: Render scene to image


OSG ships with many examples including several applications that renders the scene to image, for instance OsgAutoCapture, and OsgScreenCapture.

Whilst these applications are information rich, yet they lack sufficient conciseness and are not right to the point sometimes. It took me hours to get what I need, and for my specific task, I just need such a simple class OsgSnapshotHelper:

void Capture(osgViewer::Viewer* pViewer, std::string outputImagePath)
{
OsgSnapshotHelper* osh = new OsgSnapshotHelper(pViewer);
osh>Capture(outputImagePath);
delete osh;
osh = NULL;
std::cout << Ending Capture: << outputImagePath  << std::endl;
}

And here is my implementation, based on OsgAutoCapture example. I wrapped it to what I need and removed all unnecessary stuff into one single class, which would be very portable then.

OpenSceneGraph: texture missing – The Solutions


After developing a program using OSG, you might sooner or later package all needed executable (*.exe, *.dll) and copy/deploy them to the target machines.

It is not uncommon that when you open a model, e.g. OBJ, 3DS, FLT files, all works right, except for the textures, missing!
