| 1576 |  | Changed -u+ to be the default setting in rtrace (only). | 
| 1577 |  |  | 
| 1578 |  | Fixed binary i/o for rlam and vwrays under Windows. | 
| 1579 | + |  | 
| 1580 | + | Added tmCvLums() to tone-mapping routines using a 16-bit lookup table | 
| 1581 | + | on IEEE floats, which is also used to improve speed of COLOR conversions, | 
| 1582 | + | especially on machines with slow log() calls.  The first call to | 
| 1583 | + | tmCvLums(), tmCvGrays(), or tmCvColors() initializes the table. | 
| 1584 | + |  | 
| 1585 | + | Created optics2rad.csh script to convert from Optics 5 material output | 
| 1586 | + | to something correct for Radiance.  Built on old glazing.cal function, | 
| 1587 | + | which is actually incorrect so removed from the distribution. |
