Hi, I would like to include several attributes of openflight face records, namely Surface Material Code, and Feature ID into the scene graph. Essentialy I am looking at modifying the openflight plugin and the ive plugin to read/write these attributes. I want to use this information as a "cost" of movement for entities, so that a vehicle moves slower over dirt than over tarmac. Basically I need to be able to get access to the data using intersectors under the wheels.
I am using OSG release 2.8.3 and I have noticed that in the source code of the openflight plugin src\osgPlugins\OpenFlight\GeometryRecords.cpp the data is skipped/discarded (lines 259,260 and lines 826,827) Code: /*int16 surface =*/ in.readInt16(); /*int16 feature =*/ in.readInt16(); My question is: where is the most logical place to store this data in the scene graph. Should I just store it as user data for the stateset or the geode or should I define a new class derived from osg::StateAttribute and add an instance of this object to the stateset of the face? What would be the caveats of these aproaches? P.S. I am fairly new to OpenSceneGraph and my knowledge of OpenGL is basic. Thank you!
