| 2289 |  | depth image encoding that uses a mix of linear and reciprocal distance | 
| 2290 |  | with explicit representations of 0 and infinity.  Code for loading these | 
| 2291 |  | depth maps is in src/util/depthcodec.{h,c}. | 
| 2292 | + |  | 
| 2293 | + | Created rcode_norm tool to convert to and from 32-bit/pixel portable | 
| 2294 | + | surface normal representation, matching the one in src/common/dircode.c. | 
| 2295 | + | Code for loading normal maps is in src/util/normcodec.{h,c}. | 
| 2296 | + |  | 
| 2297 | + | Created rcode_ident tool to create indexed identifier files. | 
| 2298 | + | Code for loading these files is in src/util/idmap.{h,c}. | 
| 2299 | + |  | 
| 2300 | + | Added -o* option to rtpict to produce layered images that handle most | 
| 2301 | + | output types from rtrace (colors, surface normals, distances, IDs). |
