Detailed Description

SLSphere creates a sphere mesh based on SLSpheric w. 180 deg polar angle.

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.
