This doesn't work under OS 3.0

mrgando

I just wanted to report, as an avid iPhone developer and Space Time user, that this App doesn't work AT ALL on iPhone OS 3.0 Beta 5. The screen flickers a lot and it's unusable, please fix this, all apps in the iTunes Store should already be migrating or making their efforts to be compatible with OS 3.

Cheers , and hope I helped you somehow.

NG.

Thanks for letting me know. It's just a standard OpenGL ES template so I'm not sure why it wouldn't work on the new SDK but the new update will be out before than. Have you noticed any other problems with other OpenGL ES based apps?

First of all this app is just amazing!!! I've used it quite a bit (along with Mathematica) in the development of my own app Jasuto. The reason I'm writing this is that Jasuto exhibits the same flickering when running under the 3.0 beta OS.

The problem in my app was that I have a separate thread for rendering (instead of using timers) and the thread was trying to swap the frame buffer in the middle of a draw.

The fix is a simple mutex around the bind/render/swap OpenGL code:


&quot;lock mutex here&quot;

&#91;EAGLContext setCurrentContext&#58;context&#93;;
glBindFramebufferOES(GL_FRAMEBUFFER_OES, viewFramebuffer);

&quot;your rendering code&quot;

glBindRenderbufferOES(GL_RENDERBUFFER_OES, viewRenderbuffer);
&#91;context presentRenderbuffer&#58;GL_RENDERBUFFER_OES&#93;;

&quot;unlock mutex here&quot;

I suspect that even if you weren't using threads to render that you would encounter this. It seems that in 2.2 this was done for us, and in 3.0 it has been removed perhaps to aid in optimization?? I bet if you did the same it would fix Spacetime and I could use it again without reverting back to 2.2.1.

Again, I can't express how much I love your app and how much I actually use it. You should consider adding audio out so us DSP guys could listen to our plots

Hi Chris!

Thanks for your kind comments and advice to fix the problem. I'm going to check out the new SDK next week so I'll see if the fix you suggest works for me.

Thanks!

I was wondering if there was progress on this. It seems likely that OS 3.0 is very close to arriving. I'd really like to upgrade as soon as it comes out, but it currently looks like I'll have to choose between spacetime and OS 3.0.

Do you have an update schedule planned? Is it far off?

Thanks

Yes. There is a new update and depending on how long Apple's review process takes it should be up before June 17. I will post some screenshots soon.

Looking forward for those screenshots

me, too !!! Can't wait cause currently I can not use spacetime on my iphone...

You can see some screenshots on my iPhone apps website.

I'm going to make an official announcement here once it's live on iTunes which I was hoping would have already happened. Apple is taking forever to approve updates lately.

Also, this is being released early for iPhone OS 3.0 compatibility so file transfer will be in the next update when this is released for all platforms.

That page mentions Spacetime 4.0... How does that play with free updates?

It has been mentioned for almost a year that a new _update_ is coming, nothing about a new release, and I bought Spacetime about three months ago based on the assumption that I'd get that update when it is released...

Just curious,
Zen

Hi Zen,

There will be an official announcement made soon. The new iPhone OS update is free.

Awesome,

Looks like there were big interface revisions. Very nice. Will look forward to it's approval in the app store.

I'm a bit confused regarding upgrade to 4.0. I only have the Spacetime 3.0 version for the iphone. What do I require for the iphone OS 3.0? Does it necessitate a migration to Spacetime 4.0? If I wanted the all platform version of Spacetime 4.0; but only have the iphone version of Spacetime 3.0. Is this considered a new purchase or an upgrade? You mentioned before that you have no way of tracking previous iphone Spacetime purchases, so I'm curious how this would really work.

Hi Jon,

The iTunes purchase is completely separate from the website.

iPhone OS 3.0 is a new update from Apple. The current version of SpaceTime on iTunes does not display correctly on the new OS. The new update should be approved soon. I just want to make this notice for those who upgrade to iPhone OS 3.0 today.

Really strange that an update-approval from Apple takes so very long. When did you sent the update to the app-store, Desa?

Desa

June 10 but I received a response from them and it should be approved soon. They are taking forever for everyone. Approval time for me used to be around 5 days for me but now it seems the standard is 2-3 weeks from the iPhone developers forums. It's really absurd.

Howdy, Stranger!
