.net texture channel merge (SpecularGlossiness) test.
Test are realized using two differents approach:
- One using a simple Get/Set Pixel scheme
- The other using direct access to image memory in unsafe mode and task parallel lib support
result is straightforward
| Method | Mean | Error | StdDev |
|---|---|---|---|
| MergeGetSetPixel | 694,101.7 us | 5,032.83 us | 4,461.47 us |
| MergeLockbits | 957.3 us | 12.07 us | 11.29 us |
with:
- Mean : Arithmetic mean of all measurements
- Error : Half of 99.9% confidence interval
- StdDev : Standard deviation of all measurements
- 1 us : 1 Microsecond (0.000001 sec)
