==Rotation angles== From the two angles needed for an isometric projection, the value of the second may seem counterintuitive and deserves some further explanation. Let's first imagine a cube with sides of length 2, and its center at the axis origin, which means all its faces intersect the axes at a distance of 1 from the origin. We can calculate the length of the line from its center to the middle of any edge as {{sqrt|2}} using [[Pythagorean theorem|Pythagoras' theorem]] . By rotating the cube by 45Β° on the ''x''-axis, the point (1, 1, 1) will therefore become (1, 0, {{sqrt|2}}) as depicted in the diagram. The second rotation aims to bring the same point on the positive ''z''-axis and so needs to perform a rotation of value equal to the [[arctangent]] of {{frac|{{sqrt|2}}}} which is approximately 35.264Β°.
