| 1971 |
|
Fixed bug in indirect hemisphere sampling for some corner cases. |
| 1972 |
|
|
| 1973 |
|
Added default specular lobe to BSDF interpolation. |
| 1974 |
+ |
|
| 1975 |
+ |
Set minimum number of shadow checks before direct optimization (4). |
| 1976 |
+ |
|
| 1977 |
+ |
(Above changes included in 4.2.1 patch release.) |
| 1978 |

****** COMPATIBILITY CHANGE ******** |
| 1980 |
+ |
Made header input and output the default behavior for dctimestep and |
| 1981 |
+ |
genskyvec. |
| 1982 |
+ |
|
| 1983 |
+ |
****** COMPATIBILITY CHANGE ******** |
| 1984 |
+ |
Changed pabopto2bsdf default behavior to add 90-degree rotation |
| 1985 |
+ |
to bring pgII's definition of "up" in line with Klems axis |
| 1986 |
+ |
conventions. Introduced a new header variable "upphi" to |
| 1987 |
+ |
control this added rotation. Using "#upphi 90" in each |
| 1988 |
+ |
BSDF input file gets back the original behavior, where it |
| 1989 |
+ |
assumes that the up direction is 90-degrees from the X-axis. |
| 1990 |
+ |
The default value of 0 corresponds to PAB's definition of |
| 1991 |
+ |
the X-axis as being "up". |
| 1992 |
+ |
|
| 1993 |
+ |
Fixed bug in rsensor related to having many rows (altitude) and |
| 1994 |
+ |
few columns (azimuth) in sensitivity file. |
| 1995 |
+ |
|
| 1996 |
+ |
Fixed floating point round-off error in new Hessian calculation |
| 1997 |
+ |
for some sytems (Windows, primarily). |
| 1998 |
+ |
|
| 1999 |
+ |
Fixed bug in tensor tree BSDF code that caused bus error on |
| 2000 |
+ |
some systems, and may have been source of other errors as well. |
| 2001 |
+ |
|
| 2002 |

=================== |
| 2005 |
+ |
Version 5.0 |
| 2006 |
+ |
|
| 2007 |
+ |
Improved ambient extrapolation to avoid zero values. Actual |
| 2008 |
+ |
threshold set to 5% of recorded value. |
| 2009 |
+ |
|
| 2010 |
+ |
Changed anisotropic Gaussian and Ashikhmin models so that |
| 2011 |
+ |
illegal orientation vectors are dealt with more gracefully. |
| 2012 |
+ |
|
| 2013 |
+ |
Created wrapBSDF tool and incorporated into genBSDF along |
| 2014 |
+ |
with new rfluxmtx computation. |
| 2015 |
+ |
|
| 2016 |
+ |
Initial check-in of Roland Schregle's photon map integration. |
| 2017 |
+ |
New 5.0a version designation as suggested by Andy McNeil. |
| 2018 |
+ |
|
| 2019 |
+ |
Added left-hand coordinate sytems to rfluxmtx to correct |
| 2020 |
+ |
problems with coordinate axis orientations pointed out by |
| 2021 |
+ |
David Geisler-Moroder. |
