I have problems when I attempt to place text on a "canvas" in a 3D Tikz picture using the code from this answer: TiKZ: How to define new 2D canvas. First, when the text is placed within a scope environment, it is not typeset on the canvas at all (i.e., not with the intended 3D effect). Hence, I used the canvas option seperately for each text node. However, while that results in a 3D effect, the text is not placed where I would expect it. Please see the MWE below. For reference, I have included an x'-axis, a y'-axis, and a square that are placed correctly.
Can anyone please explain what goes wrong and how to fix it?
