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.
# Line 2145 | Line 2145 | Fixed bug in orientation of Reinhart/Tregenza sample g
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).
2164 +
2165 + Added '*' and '/' operations to rmtxop for element-wise multiplication and
2166 + division of same-sized matrices.
2167 +
2168 + Changed falsecolor so "-s" option is adjusted to match legend if one.
2169 +
2170 + Legend changes and improvements by David G-M and Stephen W.
2171 +
2172 + Fixed bug in peak extraction code that generated
2173 + "Bad call to SDqueryTreProjSA" error, reported by Lars Grobe.
2174 +
2175 + Increased maximum luminance to 10^7 in pcond to fix issue noticed
2176 + by Axel Jacobs where veiling glare not added for the sun under
2177 + some conditions.
2178 +
2179 + Increased maximum number of open files in rcontrib to the system upper
2180 + limit of 2048 rather than the default 512.
