It's my first time to trace Vincent library.
Recently,I have searched for the "depth test" for a long time.
During my searching, I found two functions, RBDepthTestLess and FragmentDepthStencil.
I used "cout" to print something out for testing if these two functions were called.
The answer is no.
Does anyone know where is the "depth test"?
Thanks.
