Stereo 3D Improvements

Stereo 3D

• AppOculus plugin (Oculus Rift VR googles integration) has been improved a lot: correct splashes, screenshots, distortion, aspect ratio, chromatic aberrations.
• Stereo separation parameter has been replaced with Stereo radius (1/2 of the separation value).
• Added stereo offset parameter (an offset after perspective projection, 0 by default).
• App3DVision and App3DSurround plugins create stereo-compatible screenshots (side-by-side).

Here is the video from Valley benchmark working in Oculus Rift mode:

...and Heaven benchmark:

Public release of updated benchmarks with Oculus Rift support is planned in July.

Render

• Better Clutter objects orientation based on normals to the surface.
• Additional render shader defines can be tweaked from UnigineScript and C++ API.
• Fixed a problem with water jittering on mobile platforms.
• Material bindings can be used in any materials, so ObjectDynamic can use any existing shaders by emulating the corresponding vertex format.
• Added a sample with orthographic rendering:data/samples/render/ortho_00.
• Added a sample with fake ObjectMesh viaObjectDynamic:data/samples/objects/dynamic_03.

GUI

• Performance optimization for complex widget hierarchies.
• Gui::clearTexture() function clears Gui texture file cache as well.
• Flash GUI uses simple FFP rendering mode to improve performance on mobile devices.
• Fixed a bug on deletion of the Widget instance with multiple registered callbacks.
• Added possibility to modify the global transfomation matrix for Gui and WidgetWindow (so you can tilt/rotate/move... the 2D GUI in 3D space).
• Added a sample with rendering Widget toImage:data/samples/widgets/render_00.
• User interface files (.ui) can include data from different files with multiple string substitutions (e.g.<include name="file.ui" foo="bar" foo2="bar2"/>).
• Perspective distortion for data/samples/widgets/canvas_00|01 samples.
• Added samples with Gui and Window transformations:data/samples/widgets/transform_00|01.

C++ API

• AddedString::substr(), String::utf8strlen() and String::utf8substr() functions.
• Added accessors for Vector and Matrix data types in the Xml class.
• Added functions for taking screenshots:Unigine::Render::ScreenshotFunc().
• Added functions for splash screen rendering:Unigine::Render::SplashFunc().

UnigineScript

• Reflection class can get type of function return value.
• Added classid() statement (can receive class signature or a variable), is_base_class() can receive its result as the first argument for faster result querying.
• typeid() can also receive type signature.
• Added bounds.h with simple bounding volume logic.
• USE_DOUBLE macros is available inWorldExpression.

Tools

• Added -n argument for ImageDDS (creates an empty image).
• Fixed a crash in 3D editor plugins on exporting files without surfaces.
• Added support for different object alignments and animation range exporting into Maya plugins.

Documentation

• Added documentation on new ObjectDynamic class.
• Updated UnigineEditor articles.
• Updated documentation on UnigineScript classes:Gui,Image, ObjectMeshDynamic,ObjectTerrain.
• Updated articles on UnigineScript function sets:engine.render,engine.editor, engine.physics,engine.system,engine.world.

Other

• NOSIGPIPE flag for Mac OS X and iOS version of Socket has been added.
• Added two samples of WinRT applications:source/samples/WinRT.
• Fixed linking problem with Clang / Mac OS X.

As promised, we have also published the video from ITEC 2013 demo (unfortunately it's a bit problematic to provide access to the build itself since the dataset is 60 GB in size already):

PS: It was only two weeks since the last SDK update, but we decided to roll out a new one before going into even more improvements and new features.
