| 2157 |  | which calls bsdf2rad then rad with a few useful default views. |

| 2160 | > | Version 5.2 (Release October 8, 2018) | 
| 2161 |  |  | 
| 2162 |  | Created psketch program to apply non-photorealistic rendering to selected | 
| 2163 |  | objects, identified by modifier name(s). | 
| 2196 |  |  | 
| 2197 |  | Modified pcomb so the first view seen in the inputs is written into header. | 
| 2198 |  |  | 
| 2199 | < | Wrote rtpict script to run rtrace in parallel mode and simulate rpict with -n option. |

| 2205 |  |  | 
| 2206 | + | Reduced bias in ambient super-sampling method. | 
| 2207 | + |  | 
| 2208 | + | Fixed bugs associated with zero transmission in chromatic tensor trees. | 
| 2209 | + | Thanks to Lars Grobe for pointing out issues. | 
| 2210 | + |  | 
| 2211 | + | Added RAYPATH searching for -f options to genrev, gensurf, genworm, | 
| 2212 | + | bsdf2klems, bsdf2ttree, and pcomb.  This makes behavior consistent | 
| 2213 | + | with rcalc, calc, and rendering tools. | 
| 2214 | + |  | 
| 2215 | + | Worked with Randolph Fritz to fix some issues with ies2rad and newer | 
| 2216 | + | IESNA63 standards. | 
| 2217 | + |  | 
| 2218 | + | Resurrected original bsdf2rad test program, renaming it bsdf2rado. Still an | 
| 2219 | + | optional build in src/cv/. | 
| 2220 | + |  | 
| 2221 | + | Fixed bug in rcontrib with virtual sources, where pretest was adding | 
| 2222 | + | to modifier accumulation buffers.  Reported by Mostapha. | 
| 2223 | + |  | 
| 2224 | + | Added an "aBSDF" material type that explicitly checks for peak extraction. | 
| 2225 | + | Its arguments are the same as the original "BSDF" type, but without the | 
| 2226 | + | thickness parameter, as proxy geometry is not supported by this new type. | 
| 2227 | + | The old "BSDF" type no longer does peak extraction under any circumstances, | 
| 2228 | + | since this behavior is superfluous for proxied geometry. | 
| 2229 | + |  | 
| 2230 | + | Added -r option to bsdf2rad (and bsdfview) to fix BSDF min and max range | 
| 2231 | + | for comparing BSDFs. | 
| 2232 | + |  | 
| 2233 | + | Fixed issue with pfilt -m option and uneven image size changes pointed | 
| 2234 | + | out by Rob Shakespeare. | 
| 2235 | + |  | 
| 2236 | + | Updates to evalglare and gendaylit from Jan Wienold, including new | 
| 2237 | + | colored sky option. | 
| 2238 | + |  | 
| 2239 | + | ========================= | 
| 2240 | + | Version 5.3 | 
| 2241 | + |  | 
| 2242 | + | Created radcompare program to compare Radiance tool output to reference outputs | 
| 2243 | + | during unit-testing. | 
| 2244 | + |  | 
| 2245 | + | Fixed issue reading very large files (> 2 GBytes) in rcollate. | 
| 2246 | + |  | 
| 2247 | + | Made picking function in rvu ignore transparent and void surfaces. | 
| 2248 | + |  | 
| 2249 | + | Added -orRxX options to rtrace to enable output of mirrored and unmirrored | 
| 2250 | + | contributions and distances to enable new types of reprojections.  This also | 
| 2251 | + | cleaned up and unified handling of effective ray lengths throughout code. | 
| 2252 | + |  | 
| 2253 | + | Bug fixes from Jan Wienold for evalglare. | 
| 2254 | + |  | 
| 2255 | + | Changed indexed (numbered) output from dctimestep to start from 0 rather | 
| 2256 | + | than 1, to make it more consistent with expected input naming. | 
| 2257 | + |  | 
| 2258 | + | Increased default sampling in bsdf2klems (-n option) to 1024. | 
| 2259 | + |  | 
| 2260 | + | Fixed an issue noticed by David G-M that was causing genBSDF to bias | 
| 2261 | + | isotropic tensor tree samples resulting in subsequent failure of | 
| 2262 | + | peak extraction with "aBSDF" type. | 
| 2263 | + |  | 
| 2264 | + | Introduced max() and min() functions to .cal library. | 
| 2265 | + |  | 
| 2266 | + | Added random incident patch sampling to bsdf2klems to improve accuracy | 
| 2267 | + | with scattering interpolation representation input (e.g., from | 
| 2268 | + | pabopto2bsdf).  The other input types already sampled incident patch area. |
