I am going to develope the 2D game in Iphone using Quartz. what is the main Difference between Quartz and QuartzCore? I have searched a lot over the internet, but only able to find out the MAC OS with Quartz Examples. If any body has any Link/URL for Examples of Quartz(2D) using Iphone Developement,which would be run in the Real Iphone Device? Also if possible than give the Link for Bunch of examples/repository for Quartz Iphone. Thanks, Mishal Shah There are a number of very nice Quartz2D and CoreAnimation animation examples in this project, from the 360iDev conference session on Core

I'd like to have a water effect on a background layer in my app. The effect doesn't need to react to touch or anything - it just needs to wave an image a little bit. CCWaves3D seem ok, but leave have nasty black artifacts around the edges when I run it. Similarly CCShaky3D. CCLiquid brings my app down from 20fps to 5fps.. Is there any other effect I might want to try out? Or perhaps I'm using the current effects in a wrong way? id shaky = [CCShaky3D actionWithRange:4 shakeZ:NO grid:ccg(15,10) duration:4]; id liquid = [CCLiquid actionWithSize:ccg(15,10) duration:1]; id wave = [CCWaves3D

I was pretty excited when I found out just how easy it is to add shadows to my UIViews on the iPhone/iPad. Just add the framework in Xcode, add the import to the top of the file: #import <QuartzCore/QuartzCore.h> Then later: self.contentView.layer.shadowRadius = 3.0; self.contentView.layer.shadowOffset = CGSizeMake(-2.0, -3.0); self.contentView.layer.shadowOpacity = 0.5; self.contentView.layer.shadowColor = [UIColor blackColor].CGColor; While this does create a beautiful shadow in my app, it also lags it to death now when the view is shown... even when launched outside of the debugger.

Greetings! I'm currently porting a web browser plugin from Win32 to MacOSX. One of the features of the plugin is that when the plugin is loaded, it spawns a separate process that serves as the "engine" of the plugin and executes drawing operations into the window of the plugin (specifically, by attaching an OpenGL context to the parent process's window and executing OpenGL rendering commands into that context). We do this because the plugin is typically loaded as a thread within the browser process, so crashes in the plugin would take down the whole browser. By partitioning the 'heavy lifting'

I'm trying to create an image mask that from a composite of two existing images. First I start with creating the composite which consists of a small image that is the masking image, and a larger image which is the same size as the background: UIImage * BaseTextureImage = [UIImage imageNamed:@"background.png"]; UIImage * MaskImage = [UIImage imageNamed:@"my_mask.jpg"]; UIImage * ShapesBase = [UIImage imageNamed:@"largerimage.jpg"]; UIImage * MaskImageFull; CGSize finalSize = CGSizeMake(480.0, 320.0); UIGraphicsBeginImageContext(finalSize); [ShapesBase drawInRect:CGRectMake(0, 0, 480, 320)];

Something I don't understand about transformations. I want to zoom in to say the top right corner of a UIView (the main view). I use CGAffineTransformScale and have tried both setting the center/anchorPoint as well as CGAffineTransformMakeTranslation to no avail. I can't figure out how to set the translation properly so that it will zoom in on this point. CGAffineTransform tr = CGAffineTransformScale(self.view.transform, 2, 2); [UIView animateWithDuration:2.5 delay:0 options:0 animations:^{ self.view.transform = tr; self.view.center = CGPointMake(480,0); } completion:^(BOOL finished) {}]; mvds
