| | Version : 0.26 |
|
| |
|
| Date Format: year/month/day
| | * Fixed a long standing unit test issue where convolve unit test would some times on some systems erratically fail |
| | | ** Appears that sometimes the random numbers caused a buffer overflow for U8 images |
| ---------------------------------------------
| | ** Now why it didn't have the exact same numbers every time when it has a fixed seed is disturbing... |
| Date : 2012/04/22
| | * Renamed EquirectangularTo* to *ToEquirectangular |
| | | ** Those classes convert pixels in * coordinates into their location in the equirectangular image |
| Version : Alpha 0.7
| | ** They are used to generate a * image from equirectangular |
