The simple answer is that you have an extra "Graphics3D[] that is not
needed with the Plot[ ] command.
Try this:
plotpoints = Show[
Graphics3D[{ PointSize[0.05], Point[{0, 0, 0}] } ],
Graphics3D[{ PointSize[0.05], Point[{0, 0, 1}] } ],
Graphics3D[{ PointSize[0.05], Point[{0, 1, 0}] } ],
Graphics3D[{ PointSize[0.05], Point[{0, 1, 1}] } ] ]
plotplane =
Plot3D[2x + y, {x, 0, 1}, {y, 0, 1}, PlotRange -> {0, 1} , ClipFill
-> None,
PlotPoints -> 50]
Show[plotplane,plotpoints]
Note the ordering has an effect. Doing Show[plotpoints,plotplane]
also works but the axes are taken from the first entry and it looks
different
