Mismatch between documentations
There is a mismatch between the old Win SDK (2.0), new Win SDK, and Mac SDK about the sign of axes of translation and rotation.
All documents state: "The home position for the device is with the negative Z-axis pointing towards the screen."
In bold are the cases that match the above sentense (mostly old Windows SDK).
oldWin newWin Mac
Translations:
| Device illustration | old | new | Mac |
|---|---|---|---|
| arrow pointing away from the screen | Translate Z-axis 0 to -MAX | Translate Z-axis 0 to MAX | Translate Z-axis 0 to -MAX |
| arrow pointing towards the screen | Translate Z-axis 0 to MAX | Translate Z-axis 0 to -MAX | Translate Z-axis 0 to MAX |
| arrow pointing up | Translate Y-axis 0 to MAX | Translate Y-axis 0 to MAX | Translate Y-axis 0 to -MAX |
| arrow pointing down | Translate Y-axis 0 to -MAX | Translate Y-axis 0 to -MAX | Translate Y-axis 0 to MAX |
| arrow pointing right | Translate X-axis 0 to MAX | Translate X-axis 0 to MAX | Translate X-axis 0 to MAX |
| arrow pointing left | Translate X-axis 0 to -MAX | Translate X-axis 0 to -MAX | Translate X-axis 0 to -MAX |
Rotations:
| Device illustration | old | new | Mac |
|---|---|---|---|
| arrow turning left | Rotate Z-axis 0 to -MAX | Rotate Z-axis 0 to MAX | Rotate Z-axis 0 to -MAX |
| arrow turning right | Rotate Z-axis 0 to MAX | Rotate Z-axis 0 to -MAX | Rotate Z-axis 0 to MAX |
| arrow turning clockwise when the user looks at the table | Rotate Y-axis 0 to -MAX | Rotate Y-axis 0 to -MAX | Rotate Y-axis 0 to MAX |
| arrow turning counter clockwise when the user looks at the table | Rotate Y-axis 0 to MAX | Rotate Y-axis 0 to MAX | Rotate Y-axis 0 to -MAX |
| arrow turning down towards the user | Rotate X-axis 0 to MAX | Rotate X-axis 0 to MAX | Rotate X-axis 0 to MAX |
| arrow turning up towards the screen | Rotate X-axis 0 to -MAX | Rotate X-axis 0 to -MAX | Rotate X-axis 0 to -MAX |
