Official feedback on OpenGL 4.5 thread

[michaelheilmann]

https://www.opengl.org/sdk/docs/man/...Separate.xhtml states that the parameter "srcRGB" "Specifies how the red, green, and blue blending factors are computed.". However, I do think the correct wording should be "Specifies how the red, green, and blue source blending factors are computed."

Hi I'm new to the forum but have been coding for over thirty years, started on basics and moving through MSDOS and VGA etc then onto windows.

I have a couple of questions:

1) With the 'new name' thread will 4.5 be the last version of OpenGL?

2) I currently code using C++ and I'm wading through OpenGL 1.X which I understand is deprecated, will support for the earlier OpenGL APIs ever be dropped in OpenGL?

The Core profile of OpenGL drops support for all the deprecated 1.x and 2.x features. Some vendors support the Compatibility profile, which allows you to use the deprecated features. If you don't want any of the deprecated features, you need to request a core profile using glX or wgl CreateContextAttribs(), using CONTEXT_PROFILE_MASK_ARB set to CONTEXT_CORE_PROFILE_BIT_ARB.

So basically we also got to move to OpenGL 4+?

My laptop only supports 2.1 at present.

Then use that. Nobody's forcing you to use OpenGL 4.x, nor is anyone forcing you to use the core profile.

Remember: OpenGL is just a document, a specification. It's not a library. Your implementation is a library. Whether it is being supported is up to whomever it is that writes your implementation.

Ah OK it's the 'its deprecated by some vendors' section sort of rings that some graphics drivers may have trouble running the software written in old gl versions. If it works fine and won't be killed off in the future all the better

Maybe it's time to buy a new laptop? Technology improves over time.
