Features and Enhancements
=========================

**Front face culling.** |HPSTHEN| 2022 now includes a front face culling mechanism which provides additional control to selectively expose internal geometric features.

**Metal-compliant driver.** Support for the Metal graphics driver is now provided to give customers an alternative to OpenGL on Apple platforms.

**OpenGL driver deprecated.** OpenGL on Apple platforms is planned to be deprecated in |HPSTHEN| 2022 SP2.

**ARKit support.** ARKit, Apple's augmented reality platform for iOS, is now supported.

**Initialization function.** A new static function, ``HPS::World::IsInitialized()``, is now available. The function is used to query whether the |HPSTHEN| system has been initialized.

**Text metrics.** A new set of functions related to text metrics has been added, which can be used to determine the overall size of text, including ascenders and descenders. See ``HPS::KeyPath::ComputeTextMetrics`` and ``HPS::TextMetrics::Options`` for details.


Functional Changes
==================

.. only:: not spatial

	**HOOPS Exchange.** |HPSTHEN| now works with HOOPS Exchange 2022.

	**HOOPS Publish.** |HPSTHEN| now works with HOOPS Publish 2022.
	
**Vulkan driver.** The Vulkan driver has been removed.

**Windows minimum version.** For developers targeting Windows, Windows 10 64-bit is now the minimum version. Support for Windows 7, Windows 8, Windows 8.1, Windows Server 2008, and all Windows 32-bit operating systems is deprecated.

**iOS minimum version.** For developers targeting iOS, iOS 11.0 is now the minimum version. The minimum required compiler is now Xcode 12.2 (LLVM).

**macOS minimum version.** For developers targeting macOS, macOS 11.0 is now the minimum version. The minimum required compiler is now Xcode 12.2 (LLVM).

**Apple sandbox.** The driver used in the sandbox is now selectable on Apple systems.

**Hardware accelerated text.** Hardware accelerated text is now on by default. Note: Known issue - when hardware acceleration is enabled in combination with text anti-aliasing of transformable text and the text background and window background are different color, then a fringe exists matching the background color around the text.
