That's a long time to be without a computer !
Something I forgot to mention - the trig functions were down using valueOpKey lookup tables which I calculated in a spreadsheet.
For the sine and cosine I found 5 degree steps from 0 to 180 were enough (interpolation is linear).
For the arcsine and arctangent I arranged the key/value pairs so that the keys would give values of 1, 2, 3, 4, etc through to 87, 88, and 89 (and 90 for arcsine) - I stopped at 89 for arctangent because tangent(a) tends to infinity as a tends to 90.
For other projects different ranges and/or step sizes may be required.
The 3Dcheapskate (also available in DAZ and HiveWire3D flavours) occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
