Release Notes

icedcoffee v0.6.8

New Features:

  • Z-sorting: ICNode does now allow for z-sorted rendering based on the zIndex property. ICNode's order, orderFront, orderBack, orderForward, and orderBackward have been reworked to affect z-indexes rather than the node's physical order.
  • Node metrics: ICNode does now provide an origin property allowing you to define the node's local origin w.r.t. to the space occupied by its contents. What is more, ICNode provides a couple of new methods for centering, e.g. center, setCenter:, localCenter, and setLocalCenter:.
  • Vastly improved picking performance on iOS devices using CoreVideo texture caches (no more stalling framebuffer readbacks).

New Test Projects:

  • Added ShaderTest (Mac) demonstrating the implementation of a simple animated fragment shader sourced from http://glsl.heroku.com/.

Important Changes:

  • The ICNode::order method has been renamed to ICNode::index.
  • The ICLine class has been renamed to ICLine2D.

icedcoffee v0.6.7

New Features:

  • GPUImage integration: OpenGL ES based video filtering, camera and movie file access
  • Default framework shaders are now embedded in the icedcoffee binary and do no longer need file-based build phase integration
  • Added support for loading texture images from URLs in ICTextureCache and ICTextureLoader

Deprecations:

  • ICTexture2D::size and ICTexture2D::sizeInPixels are no longer deprecated, as we've decided to allow for differing texture surface/content sizes in ICTexture2D.

Important Changes:

  • The semantics of ICTexture2D::size have changed; developers should replace occurrences of ICTexture2D::size with ICTexture2D::displayContentSize in their application code.
  • The keys used by ICTextureCache have changed: the class does now use [NSURL absoluteString] as the key for textures loaded from files or URLs. File paths are converted to file urls internally.

icedcoffee v0.6.6

New Features:

  • Support for integration with Interface Builder (on both iOS and Mac OS X)
  • Support for high resolution fonts on retina displays on iOS

Deprecations:

  • ICCamera::setupScreen is deprecated due to misspelling. Use ICCamera::setUpScreen from now on.
  • ICHostViewController::setupScene is deprecated due to misspelling. Use ICHostViewController::setUpScene from now on.
  • ICTexture2D::initWithData:pixelFormat:pixelsWide:pixelsHigh:size: is deprecated as it does not support differen resolution types and is kind of misleading. Use initWithData:pixelFormat:textureSize:contentSize:resolutionType: from now on.
  • ICTexture2D::size is deprecated. Use ICTexture2D::contentSize or ICTexture2D::displayContentSize instead. The semantics of ICTexture2D::size were incorrect. See the changelog for details.
  • ICTexture2D::sizeInPixels is deprecated. Use ICTexture2D::contentSizeInPixels instead.

Replaced methods (possible backwards incompatibility):

  • ICScene::setupSceneForPickingWithVisitor: has been removed and was replaced with ICScene::setUpSceneForPickingWithVisitor:. The semantics of the method were not changed.
