naming the vertex attributes

[MichaelJPCT]

say i created a plane with ExtendedPrimitives.createPlane,
in the object3d there is a mesh, and the mesh has vertex positions, uv coords, etc.
they are like vertex attributes, but they are not in VertexAttribute objects.

if i want to use shader with this plane and i need to access vertex position, normal, uv coords... how can i access them?

Desktop GL provides some magic attributes for that, like gl_position and such. In the wiki, you can find some shader examples for desktop OpenGL that should illustrate that.
