Ok, I've done a quick test on my machine. The results are quite
surprising. Here the list for a remap from 4000x2000 equirect to 6
cubefaces with 1200x1200 each. I've used a modified version of my
cubefaces batch file with fast transform turned off.
filter number and execution time (mm:ss,0)
0 00:41,9
1 00:40,1
2 00:43,6
3 02:28,9
4 00:46,7
5 00:37,8
6 00:37,2
7 05:32,6
8 00:41,8
9 00:41,8
10 00:41,9
11 00:41,6
12 00:42,0
13 00:41,6
14 00:41,6
15 00:41,6
16 00:41,6
17 00:41,7
18 00:42,1
19 00:44,9
20 00:43,8
21 00:42,9
Filter 8 to 21 are the new anti-aliasing filters. Interesting that
only the older low quality interpolators poly3, bilinear and nearest
neighbor are slightly faster. The sinc filters are significantly
slower...
If anyone wants the batch files for own tests please mail.
best regards
