Yes. We know that it after the fixes (
http://vtk.org/gitweb?p=VTK.git;a=commit;h=ffe79ee12dcdc7b32defa9523567075a73dccbe7),
it still does not work on certain mac/GPUs. We use the vtkSmartVolumeMapper
that defaults to software rendering when the GPU renderer says that it
cannot render. Its better for the GPU mapper to conservatively state that
it cannot render rather than state that it can and fail on certain
platforms/hardware combinations.
Rather than enable it on all Macs, I would recommend that you do is to
selectively enable it only on known combinations of Mac/ graphic cards.
Here's what I know :
1. On my iMac
- Snow Leopard 10.6, ATI Radeon HD 4670, OpenGL 2.1 ATI-1.6.18
- Results in a crash (of the worst kind). It freezes the machine,
necessitating a restart.
- Attached is the iMac output log of the text.
- Attached is the iMac glxinfo.
The error is
Validation Failed: Sampler error:
Samplers of different types use the same texture image unit.
- or -
A sampler's texture unit is out of range (greater than max allowed or
negative).
2. On my macbook
- NVidia GeForce
9400M<http://www.nvidia.com/object/product_geforce_9400m_g_us.html>
(integrated
video card, that uses 256MB of the main system memory)
- 10.5.8 (Leopard)
- All tests pass except all tests that use shading. They are
TestGPURayCastCompositeBinaryMask
TestGPURayCastCompositeShadeMask
TestGPURayCastCropping
3. A user has reported that it works on Lion, Nvidia card (
http://markmail.org/message/7mmcz5euptb56fw5). Not sure what card he is
referring to.
4. Bob O'Bara (Kitware) had once sent me an email reporting that it works
on his iMac and MacbookPro, both running ATI cards. (not sure if he tried
it with shading ON, and not sure about the OS (version) they run).
