Next, the cube is rotated ±45° about the vertical axis, followed by a rotation of approximately 35.264° (precisely arcsin 1⁄ √ 3 or arctan 1⁄ √ 2, which is related to the Magic angle) about the horizontal axis.
For example, with a cube, this is done by first looking straight towards one face. The term 'isometric' comes from the Greek for 'equal measure', reflecting that the scale along each axis of the projection is the same (unlike some other forms of graphical projection).Īn isometric view of an object can be obtained by choosing the viewing direction such that the angles between the projections of the x, y, and z axes are all the same, or 120°. Camera rotations needed to achieve this perspective Classification of Isometric projection and some 3D projections
