I released the Alice app and this issue *was* previously fixed by un-commenting</p> <p><code>[[CCDirector sharedDirector] setDepthBufferFormat:kDepthBuffer16];</code></p> <p>in the application delegate and then using the solution in <a href="http://code.google.com/p/cocos2d-iphone/issues/detail?id=751" rel="nofollow">http://code.google.com/p/cocos2d-iphone/issues/detail?id=751</a> </p> <p>looks like the new iPad OS somehow broke the fix though - I'm now seeing glitches on the left edge. Issue has already been re-opened, just heads-up for anyone else struggling with this. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-42974 Wed, 23 Jun 2010 03:05:43 +0000 cjkeeme 42974@http://www.cocos2d-iphone.org/forum/ <p>Yeah, I just learned the book 'Alice' has released an update with the page curl effect solved. Anyone with any thoughts on what to do to beat this problem? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-42960 Wed, 23 Jun 2010 01:21:11 +0000 brendang 42960@http://www.cocos2d-iphone.org/forum/ <p>Wow, I was literally just here to type the same question. I tried the hack mentioned in the issue list, but no help. Really looks crappy when all those triangles flicker on the left.</p> <p>IS there any option or alternative to this particular page-turn transition? Telomere uses a page-turn, and they seem to have beat the problem. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-42958 Wed, 23 Jun 2010 01:08:54 +0000 cjkeeme 42958@http://www.cocos2d-iphone.org/forum/ <p>Is there any update on this? We are also having issues with the page curl transition artifacts. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-26037 Tue, 09 Feb 2010 01:56:19 +0000 riq 26037@http://www.cocos2d-iphone.org/forum/ <p><a href="http://code.google.com/p/cocos2d-iphone/issues/list" rel="nofollow">http://code.google.com/p/cocos2d-iphone/issues/list</a> </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-26035 Tue, 09 Feb 2010 01:01:48 +0000 cublah 26035@http://www.cocos2d-iphone.org/forum/ <p>What's the link for posting a bug I haven't posted one in a while </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-26034 Tue, 09 Feb 2010 00:56:35 +0000 riq 26034@http://www.cocos2d-iphone.org/forum/ <p>@<a href='http://www.cocos2d-iphone.org/forum/profile/53'>cublah</a>: could you open a bug ?

It only seems to happen on the left hand side when the animation starts, it looks possibly like a z buffer problem. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25993 Mon, 08 Feb 2010 19:11:25 +0000 riq 25993@http://www.cocos2d-iphone.org/forum/ <p>@<a href='http://www.cocos2d-iphone.org/forum/profile/53'>cublah</a>: seems to be a bug. Can you reproduce it in v0.8.2 ? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25992 Mon, 08 Feb 2010 19:03:02 +0000 cublah 25992@http://www.cocos2d-iphone.org/forum/ <p>Ok...I enabled depth buffer and I still get some artifacts on the left hand side of the screen at the start of the animation, you do get them in the test transition as well but I think because it's landscape you don't see them that clearly (probably because of the type of images too).</p> <p>I did a test project and made a movie. <a href="http://www.purplezoo.com/pageturn2.mov" rel="nofollow">http://www.purplezoo.com/pageturn2.mov</a> </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25975 Mon, 08 Feb 2010 16:46:18 +0000 cublah 25975@http://www.cocos2d-iphone.org/forum/ <p>Also is there a way so it doesn't show the back of the of the page as it's tearing of? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25973 Mon, 08 Feb 2010 16:09:11 +0000 cublah 25973@http://www.cocos2d-iphone.org/forum/ <p>ah..ok I thought I had turned on the depth buffer but I was running from a test project and missed it. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25972 Mon, 08 Feb 2010 15:58:13 +0000 crmagicxxx 25972@http://www.cocos2d-iphone.org/forum/ <p>Ok, I'll try doing what you suggested</p> <p>Regards </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25971 Mon, 08 Feb 2010 15:44:42 +0000 riq 25971@http://www.cocos2d-iphone.org/forum/ <p>@<a href='http://www.cocos2d-iphone.org/forum/profile/34'>crmagicxxx</a>:<br /> I think that the depth buffer will affect the rendering, so the test that I would do is:</p> <p>- Use the sprite performance test as a template, but I would create a new test (eg: DepthBufferPerformanceTest). I would use only the tests that do not trigger that "fill rate" limit, for example, tests 10-11-12, and I would include only the A tests.<br /> - So, I would add 3 options: 0-bit, 16-bit and 24-bit depth buffer.</p> <p>And another thing that I would do is to place the sprites at different Z values (OpenGL Z, not cocos2d Z).<br /> Example:<br /> sprite.vertexZ = random(-1000,1000);</p> <p>the 0-bit depth buffer should not perform worse than the 16-bit or 24-bit buffers. If so, something really strange is happening.<br /> Instead, it should perform a little bit better, but I'm not sure if it should perform better in all tests. </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25969 Mon, 08 Feb 2010 15:15:19 +0000 crmagicxxx 25969@http://www.cocos2d-iphone.org/forum/ <p>Ok Riq, I can do it, just tell me how? :)<br /> Should I open your standard performance test and compare results or what? For particles, sprites and touches? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25966 Mon, 08 Feb 2010 14:56:57 +0000 riq 25966@http://www.cocos2d-iphone.org/forum/ <p>@<a href='http://www.cocos2d-iphone.org/forum/profile/34'>crmagicxxx</a>: It will consume more memory, and probably it might be a little bit slower when rendering some scenes... but I didn't do any performance test, so I'm not sure.<br /> Are you interested in doing them ? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25964 Mon, 08 Feb 2010 14:32:12 +0000 crmagicxxx 25964@http://www.cocos2d-iphone.org/forum/ <p>@Riq</p> <p>I saw that default depth buffer is kDepthBufferNone. But if we change it to 16 or 24, so transitions like page turn can work, are there any performance issues that can emerge from a change? For example I know that changing pixel format from 16bit to 32bit greatly reduce FPS, but I don't know anything about depth buffer and its impact on FPS...</p> <p>Thanks </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25962 Mon, 08 Feb 2010 14:19:38 +0000 riq 25962@http://www.cocos2d-iphone.org/forum/ <p>you are using a depth buffer, right ? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25952 Mon, 08 Feb 2010 12:06:03 +0000 cublah 25952@http://www.cocos2d-iphone.org/forum/ <p>anyone? </p> http://www.cocos2d-iphone.org/forum/topic/4324#post-25868 Sun, 07 Feb 2010 17:56:58 +0000 cublah 25868@http://www.cocos2d-iphone.org/forum/ <p>What happened to the page turn transition? It's all spiky as it goes off screen.</p> <p>I would really like to use this transition can anyone provide any insight? </p>
