Hi,
I'm a new guy to OSG. I use OSG version 3.0.1.
When I wanted to view a terrain with switch image layers, I found that the
optional image layer was not displayed right.
So, I looked into the source code of osgTerrain/GeometryTechnique.cpp.
I found that from line 482 ("osgTerrain::ImageLayer*
imageLayer(dynamic_cast<osgTerrain::ImageLayer*>(itr->first));
") in the function "void
VertexNormalGenerator::populateCenter(osgTerrain::Layer* elevationLayer,
LayerToTexCoordMap& layerToTexCoordMap)
", if "itr->first" can't be converted into imageLayer, then it will be tried
to converted into ContourLayer. However, itr->first can be swithLayer with an
active image layer. How about patching this part of code with the dealing of
switchLayer?
...
Thank you!
Cheers,
Yashuai
