so. It seems that apple guys are getting the LION next month so is houdini tested with that and at which build?

It would be very bad to discover after installing LION houdini don't work anymore.

Errr the developers version of lion was released last Monday > I think your expecting a bit much > just wait.

Talking about this, it is supposed Lion will support opengl 3.2, if this is truth then most of houdini opengl capabilities should work in Lion.
Seems drivers are not yet ready in the latest lion releases to support it, but it is in the feature list, I don't know if SESI knows more about this, or have received some news from Apple about the upgrade to opengl 3.2.

Talking about this, it is supposed Lion will support opengl 3.2, if this is truth then most of houdini opengl capabilities should work in Lion.

From what I've seen, the last remaining issue with Nvidia hardware & OSX has been cleared up on Lion, which was the sole remaining OpenGL difference between OSX and an up-to-date Linux or Windows platform. This will allow High Quality lighting to work in all its glory, which was previously disabled on OSX and Nvidia.

High Quality Lighting has always been working on AMD cards on OSX, however.

This are excellent news twod.
I understand new drivers in Lion enable the needed features to get high quality lighting?
I am wondering if they resolved all the refreshing problems with nvidia cards as well.
I cant believe they are jumping to 3.2 …
Probably one just one day. Mac will have docents drivers.

There are actually two OpenGL drivers in OSX 10.7 - the legacy OpenGL 2.1 driver (with some GL 3.x extensions) which Houdini 11 will use, and the new core OpenGL 3.2 driver. The only unfortunate part about the new driver is that it does not support any features that were deprecated in OpenGL 3.1. The net result is that if you want to use the GL 3.2 driver, you need to remove *all* older OpenGL features and code specifically for OpenGL 3.2. On the other hand, if you use the older driver, you don't gain access to many of the newer features. So it really draws a line in the sand. Luckily there isn't much hardware that is OpenGL 2.1-only in Macs.

In contrast, in recent drivers, Nvidia and AMD support OpenGL 4.1 down to OpenGL 1.0, making it a bit easier to migrate to newer GL features. Apple is choosing the “all or nothing” approach, it seems.

As usual Apple making life easier for OpenGL developers.
Well, for me is much more important that Houdini runs smoothly, without refreshing problems, with popup menues that draw correctly, etc … rather than getting all the bells and whistles of opengl high quality lighting.
Are they updating drivers for both nvidia and amd/ati cards?
Will the nvidia series 8000 cards affected by this update (I think this will be too much for Apple)
And finally any performance test compared with previous drivers version?
Thanks twod, these info is really appreciated.

I don't understand why Apple don't choose directly open GL 4.x ??

Unlike Nvidia and AMD, Apple's GL implementation must support Intel, AMD and Nvidia hardware for all the hardware they have shipped in their Macs. I suspect this makes for a lot of work. A lot of features in OpenGL 4.x look like they wouldn't be trivial to implement (Nvidia and AMD are still working on getting it all right). Implementing the core OpenGL 3.2 profile allows them to get DirectX 10 equivalence, and they can avoid implementing the older fixed-function pipeline as well.

Personally, I'm all for the old fixed-function pipeline being retired. It's limited and very error-prone. However, it did have a few features that allowed simple things to be coded very quickly (like drawing simple shapes). Redoing those using a new API isn't much fun

Like always, thanks twod for these usefuls informations

I'm an Apple fan from the beginning (my first Apple was an Apple IIe).
But, since a few years, Apple look at most iOS and iDevices, so be ready, in few years, you will need coding Houdini for iOS !!

As a Mac developer I migrated to Lion with the release of the GoldMaster. Everything works fine (even Vue6), except my Houdini 10 - It crashes directly after the Logo… Really disappointing 8(

Did you try to reinstall it ?

Just FYI, i had the problem with 11.0.775, Houdini was crashing just after launched.
Just to be sure, i downloaded the last 11.0.799 and I don't know if it is the new build or the reinstallation. But now, all works like a charm.

I did a clean install of my system on a new hd. I tried 10.0.953

Argggg. So it is definitely the release.
Lion ‘seems to be’ official after tomorrow (14th July). It would be great to know if some news releases for H10 & H11 would be available at the same time than Lion.

H11.0.799 on Lion don't use the new OpenGL 3.x capabilities on my MacBook Air. I don't try it on my workstation because it is a production computer.

Edit: MacBook Air with have a 320M nvidia card and it is an OpenGL 2.1, so i can't have openGL 3.x on it

A fix for Lion was made in H11.0.797. It seems that we forgot to add a journal log for it and I've now remedied that. As far as I know, there are currently no plans to support H10 on OSX Lion.

Thanks Edward for this fast reply

Perhaps can you too add ‘Mac OSX 10.6 (64-bit Leopard/Snow Leopard) - Mac OS 10.7 (64-Bit Lion)’ in definition of last compatible releases ?
Perhaps it's too early
