Osx opengl 4.3

Having OpenGL 3.3, I assumed I’d at least be able to get an ES 3.0 context up and running. That User Guide says ES 3.0 emulation requires OpenGL 3.3, but doesn’t mention requirements for ES 3.1 emulation.
#Osx opengl 4.3 driver#
It does describe the platform differences, but says that “libGLESv2.dylib” is the “PVRVFrame driver file for OpenGL ES 2.0 and higher”. That only lists the OpenGL requirements for emulating the various GL ES versions.
#Osx opengl 4.3 manual#
The other document I looked at was the PVRFrame User Manual in the SDK. I’d also hope to see something in the release notes: It says SDK v3.3 supports GL ES 3.1 emulation, and the only mention of Windows / OS X / Linux say that the SDK supports all of them. The SDK announcement page seems like a good place to start: (If you know of one I’d be very grateful to hear).Ī heads up in the docs would have saved me some time and energy, though. I don’t know of another emulator that even claims to support ES 3.1 (and for free). I can’t complain about the lack of support. I don’t think VMWare or Parallels support a high enough OpenGL version, so my only option is to boot natively into Windows or Linux, but that can be a bit of a break in the workflow Given the number of iOS & Android studios there must be, I’d expect iOS would be a primary development platform for a lot of people. I dunno why Apple won't keep up to date with the latest versions of OpenGL, but I can only see it as a limiting factor, especially if Apple is any way. TBH, I’m kind of surprised more people haven’t raised it. I'm looking into Regal for OSX since it may be the only possible way to move beyond Apple's implementation of OpenGL 4.1 on Mavericks. While ‘std140’ is very clearly defined, ‘shared’ and ‘packed’ can be implementation dependent (giving room for optimizations but sacrificing predictability).It would really be helpful to have OS X supported, but it sounds like it won’t happen any time soon.

There are three layout qualifiers: ‘std140’, ‘shared’ and ‘packed’. Uniform block layout qualifier ‘packed’ results in GLSL compile errors I did this in my original program but forgot it in the test app, shame on me. Update: As arekkusu noted in the OpenGL Forums, you have to (re)link the program after changing the fragment data location with glBindFragDataLocation.

And it works fine on all systems (Win/Linux, NVidia/AMD) but not on MacOS X. glClear works in this setup and occlusion queries tell me the correct number of fragments being created, but nothing from rendering happens to go into the attached texture.Īgain, here’s a test app that shows the issue on 10.7.4. This should give the same results as not messing with glDrawBuffers and setting the fragment out location to 0 (in case of only one output, 0 is also the default). Struct Defective ) (in case of one attachment). The problem is this: Imagine you have struct in your shader where you mix integer and float types: I originally found this in December 2011 and filed a report (#10518401). Oh, and let others know (blogpost, a comment here, the OpenGL forums, Apples forums, wherever, just make it simpler for the next guy to google the problem). In case you find a bug, report it at Apples Bug Reporter even if you know it’s already reported – the more reports Apple gets, the higher the bug priority will be set – sad, but true. So here I want to quickly describe the still open bugs I had to deal with in case you have the same problem (In this case, I guess you googled it, came here and will see that this is in fact a bug). Bugs in Apples software can sadly be present for month and even year.
#Osx opengl 4.3 update#
Sadly, Apple happens to be not as good as these companies at doing this job.īut hey, you find a bug, report it and the next update will provide you with a fix, right? I wish it would be this quick.
#Osx opengl 4.3 drivers#
Providing an up-to-date and performant OpenGL implementation is not an easy task, and you have to wonder why Apple tries to do this on there own and not letting Intel, NVidia and AMD provide the drivers as they do on Windows and Linux. Once in a while I run across a bug in Apples OpenGL implementation.
