Earlier this week I mentioned an example and nice simple tutorial demonstrating how to recreate Stonehenge in 3D with Scene Kit.
Here’s another nice tutorial for learning Scene Kit by Ricardo Rendon Cepeda.
The tutorial goes through an in-depth explanation of Scene Kit, setting up a project, setting up a scene’s camera, lighting and background, and goes through the creation of a simple atom visualization app drawing the carbon atoms for several different substances complete with coloring and material.
Last month I mentioned some nice iOS 8 source code examples including basic examples on setting up 2D and 3D scenes within SceneKit.
Here’s a nice step-by-step tutorial from Ryan Shelby showing how to re-create Stonehenge in SceneKit.
The tutorial provides a nice explanation of 3D coordinate systems, and goes through setting up the scene background, sky, and camera, laying out the stones, and adding material to the stones.
Earlier this year I mentioned a collection of iOS 8 source code covering many new features within the iOS 8 SDK including a basic example of notifications with custom actions.
Here’s a nice step by step tutorial submitted by Yari D’areglia showing how to use the new notification actions in iOS 8 to create interactive notifications.
The tutorial covers how to set up your notifications with custom action buttons, schedule your notifications, and handling the action chosen by the user.
Here’s a nice tutorial from Ryan on creating blurs, and utilizing the new visual effects classes found in iOS 8.
The topics covered in the tutorial include:
- How the typical Gaussian blur algorithm works
- How to use blurs to improve your app’s design
- Taking a screen snapshot and applying a blur
- Adding vibrancy to a blur (with UIVibrancyEffect)
- Creating different blur effect styles (with UIBlurEffect)
Here’s a nice step-by-step guide demonstrating how to use the Local Authentication framework to easily create an authentication prompt that can be bypassed using Touch ID.
The tutorial provides a nice overview of the Touch ID feature and security considerations then goes through the process of creating a simple app with a prompt that can be bypassed by using the fingerprint sensor.
