OpenGL Extensions Viewer provides info about your OpenGL accelerator. Many OpenGL extensions, as well as extensions to related APIs, have been defined by vendors. The extension registry is maintained by SGI.
Contains specifications for all known extensions, written as modifications to the appropriate specification documents
Defines naming conventions, guidelines for creating new extensions, and writing suitable documentation
Displays the vendor name, the version implemented, the renderer name, and the extensions of the current OpenGL 3D accelerator
With internet connection, retrieves the specifications that explain the available extensions
What's new in OpenGL Extensions Viewer
Fix rendering tests in Core Profile. Fix the OpenGL 3.2 rendering test on some devices.
While this may be academically interesting of what practical use is it, given that all Mac's, other for Mac Pro's have non-swapable graphics cards? Even with MacPro's the 3rd party graphic card, options are limited.
The time that knowing such parameters is actually useful is when making a purchase decision on a new Mac, or when replacing a graphics card in a Mac Pro. In either case you have to rely mostly on the vendors published specifications.
Something strange I noticed is how in the previous version my OpenGL 2.1 scores were incredibly low but with the latest release (3.32) I'm getting close to 400fps - I am wondering whether the GLviewer has been optimised thus when it is properly optimised for the Apple OpenGL implementation the performance improves. My 2.1 score for the record went from 122 to 391 - something definitely must have changed - I've yet to test it on my iMac but I'm pretty certain that I'll see the same sorts of results.
great but I wish there was more demanding geometry/normal/parallax/Cg shader stuff in it for the benchmark. It's hard to see the benefits of my Quadro FX 5600 with a cube. Throw a few models in - a million-poly spec and normal mapped ZBrush model or something.
I had hoped to use this to bench Leopard vs Tiger on a less than supported machine. G4 450mhz, Radeon 7000, 512MB of RAM. Leopard was surprisingly responsive on it, and OpenGL Extensions Viewer ran fine, benching up to 1.4 and pegging it around 73-74fps on each. In 10.4.10...it crashed. Every time. So there's something buggy in this release, because I could not bench it on the old, supported OS, but I could on the new, unsupported (on that machine) OS. Strange.
Hi guys, its Ray again, I've read the replies that were posted below. All have good points, what I was saying was that 2.15, only worked with my last build of 10.2.8 Jaguar.
I now have the last build of 10.3.9 Panther, I also plan to upgrade my ATI card.
I have a G3B&W, 500 mghz, and 1024 of RAM
I also plan to upgrade the Processor too.
After the upgrades I'm sure that 2.27 will work fine.
Great Tool - no other shows that Informations.
Interesting informations about what OpenGL funct. are implemented and which are not (NV, Apple(ATI) has to work).
MAC OS X OpenGL is a bit behind other OpenGL Systems.
Definitely a pretty hot app! Appreciated intuitiveness despite the amount of information that can be culled from this app... and a built-in OpenGL benchmark and compatibility tester (well, more compatibility than a benchmarker- an old Rage128 could handle those tests)!
