Added -rf and -rb options to rmtxop to load front or back reflectance |
2402 |
|
matrix data from XML file rather than transmission. (Lars Grobe suggested.) |

Improved behavior for coincident surfaces with different materials. |
2405 |
+ |
Rather than returning one surface or the other based on floating-point |
2406 |
+ |
vagaries, opaque materials are now preferred over transparent ones. |
2407 |
+ |
If the materials are both transparent or both opaque, then whichever |
2408 |
+ |
surface appeared later in the scene description will be selected. |
2409 |
+ |
This came of a request for consistent behavior with legal CAD output |
2410 |
+ |
from Peter Apian-Bennewitz. |
2411 |
+ |
|
2412 |
+ |
Added explicit tests for on-edge intersections with polygons. This should |
2413 |
+ |
eliminate stray rays and tiny light leaks that often appear even in |
2414 |
+ |
well-constructed geometry. |
2415 |
+ |
|
2416 |
+ |
Added "-s up" option to pabopto2bsdf to allow for 180 degree symmetry, |
2417 |
+ |
meaning that data repeats after 180 degree rotation (as distinguished |
2418 |
+ |
from "-s bilateral" whose data is mirrored about a vertical plane). |
2419 |

Thanks to Helen Rose Wilson for the suggestion and informing me that |
2420 |
+ |
such a thing exists. |
