* We expect slight differences in rendering between the OpenGL and |
|
51 |
* software pipelines due to algorithmic and rounding differences. |
|
52 |
* The purpose of this test is just to make sure that the OGL pipeline |
|
53 |
* is producing results that are "reasonably" consistent with those |
|
54 |
* produced in software, so we will allow +/-TOLERANCE differences |
|
55 |
* in each component. When comparing the test and reference images, |
|
56 |
* we add up the number of pixels that fall outside this tolerance |
|
57 |
* range and if the sum is larger than some percentage of the total |
|
58 |
* number of pixels. |
|
59 |
* |
|
60 |
* REMIND: Note that we have separate thresholds for linear and radial |
|
61 |
* gradients because the visible differences between OGL and software |
|
62 |
* are more apparent in the radial cases. In the future we should try |
|
63 |
* to reduce the number of mismatches between the two approaches, but |
|
64 |
* for now the visible differences are slight enough to not cause worry. |
