I'm attempting to anti alias by rendering to a larger texture then scaling down the texture. My code looks like this
glViewPort(0,0,GraphicsWidth()*2,GraphicsHeight()*2)
glFrustum(0,Graphicswidth()*2,0,GraphicsHeight()*2,1,1000)
glDrawElements()
glViewPort(0,0,GraphicsWidth(),GraphicsHeight())
glFrustum(0,GraphicsWidth(),0,GraphicsHeight(),1,1000)
For some reason it's only rendering the bottom left corner of the FBO.
