Detailed Description

SLDisk creates a disk mesh based on SLRevolver.

Remarks
It is important that during instantiation NO OpenGL functions (gl*) get called because this constructor will be most probably called in a parallel thread from within an SLScene::registerAssetsToLoad or SLScene::assemble function. All objects that get rendered have to do their OpenGL initialization when they are used the first time during rendering in the main thread. For this mesh it means that the objects for OpenGL drawing (_vao, _vaoP, _vaoN, _vaoT and _vaoS) remain unused until the first frame is rendered.
