| 2060 |  | ================================= | 
| 2061 | < | Version 5.1 | 
| 2061 | > | Version 5.1 (Released 8/17/2017) | 
| 2062 |  |  | 
| 2063 |  | Fixed issue with vchars.mta and symbols.mta not being installed in | 
| 2064 |  | the appropriate metafile library location, with help from Rob G. | 
| 2142 |  | Rewrote bsdf2rad from ground up and made it a standard part of build. | 
| 2143 |  |  | 
| 2144 |  | Fixed bug in orientation of Reinhart/Tregenza sample generator in rfluxmtx. | 
| 2145 | + |  | 
| 2146 | + | Added ability to perform shadow-testing through unproxied BSDFs with strong | 
| 2147 | + | through (direct-direct) component. | 
| 2148 | + |  | 
| 2149 | + | Added {+|-}a options to genBSDF and bsdf2ttree for switching off reciprocity | 
| 2150 | + | averaging. | 
| 2151 | + |  | 
| 2152 | + | Added bias to see through BTDFs with a strong "through" component | 
| 2153 | + | rather than scattering view rays.  This is in lieu of peak extraction, | 
| 2154 | + | which looked to be too difficult from an implementation standpoint. | 
| 2155 | + |  | 
| 2156 | + | Added bsdfview tool analogous to objview but for BSDF files (XML and SIR), | 
| 2157 | + | which calls bsdf2rad then rad with a few useful default views. | 
| 2158 | + |  | 
| 2159 | + | ========================= | 
| 2160 | + | Version 5.2 | 
| 2161 | + |  | 
| 2162 | + | Created psketch program to apply non-photorealistic rendering to selected | 
| 2163 | + | objects, identified by modifier name(s). |
