Test Image for test TestTextureRGBA
Hello,
6 VTK tests that rely on non-power-of-two texture support fails on some
versions
of Mesa:
Mesa 7.0.4: OK
Mesa 7.4.2: broken
Mesa git: broken
The 6 tests passed with proprietary nVidia drivers 180.44 with GeForce 6 and
Quadro FX 3600M.
The following 2 tests use a 100x19 RGBA texture:
TestTextureRGBA
TestTextureRGBADepthPeeling
The following 4 tests use a 200x200 RGB texture:
TestTStripsColorsTCoords
TestTStripsNormalsColorsTCoords
TestTStripsNormalsTCoords
TestTStripsTCoords
Here is a build using Mesa GIT, with the failing tests listed:
http://www.cdash.org/CDash/viewTest.php?onlyfailed&buildid=338063
You can click on the failed button to get a detail report of the test, notably
a comparison between the test image and the valid image
For example, if you click on TestTextureRGBA, you get:
http://www.cdash.org/CDash/testDetails.php?test=23560070&build=338063
For example, for test TestTextureRGBA, GL_TEXTURE_MIN_FILTER and
GL_TEXTURE_MAG_FILTER are set to GL_LINEAR, GL_TEXTURE_WRAP_S and
GL_TEXTURE_WRAP_T to GL_REPEAT.
