New Features
============

**Animation API beta release.** Simple keyframe animation is now available in beta form. The animation API provides control of visibility, location, orientation, and visual attributes in a scene over time. Animations are composed of separate channels for each parameter type to be interpolated between keyframe states in the scene. An additional player object provides the controls for playing the animation. The details can be found in the Programming Guide page about :doc:`animation </prog_guide/0306_animation>`, and in the Reference Manual.

**OpenGL2_Mesa driver.** A new driver is available, based on OpenGL Mesa. This is a software driver meant for systems without GPU hardware. See the :ref:`Device Guide <prog_guide/appendix_device_guide:OpenGL2Mesa>` for more details.

**Hardware accelerated text.** Hardware accelerated rendering of transformable text is now available for a wide variety of use cases, improving performance when significant amount of text is present in scenes. Accelerated rendering is currently supported on text attribute shape changes (not position), text with backgrounds, and text using driver fonts. Using this feature is optional, off by default, and can be enabled using ``HPS::PerformanceControl::SetTextHardwareAcceleration(bool in_state)``. The text must be transformable and segment display lists must be enabled for this option to take effect. Note currently there is not support for greeking, under/overlined text, strikethrough, per-character attributes and visible text leader lines.

	**Physically Based Rendering.** Physically Based Rendering is now supported on mobile platforms, enabling application developers to provide enhanced rendering realism on those platforms. Note that glTF data is not currently supported on mobile platforms when the data is loaded by HOOPS Exchange. PBR material data will have to be loaded through other mechanisms such as the HSF format.

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

.. only:: not spatial

	**HOOPS Exchange.** |HPSTHEN| now works with HOOPS Exchange 2021 SP1.

	**HOOPS Publish.** |HPSTHEN| now works with HOOPS Publish 2021 SP1.

**SketchUp.** |HPSTHEN| now includes support for SketchUp 2021. The SketchUp Sprocket requires Visual Studio 2019 Redistributable.
