terribly sorry. There was scaling problem.
I just scaled up the model size to multi folds.
I could get it.
But tethering to model is not working fine for me.
Instead, if setTherNode (to the geotransform node) is set at node callback, it is happening.
Second thing, the model is appearing complete white. Setting of GL_LIGHTING to on/off, switches
only the model color to complete white/black. But model alone rendered complete texture is coming
fine with no issues.
