The new Murl Engine Build 1.00.5880Beta is available for download. This is an regular update release with several improvements and fixes.

API Changes

• Added IAppStoreProduct::GetPurchaseSignature(), see the method documentation for platform specific data content.
• Added Resource::IDictionary, together with Resource::XmlDictionary and Resource::NativeDictionary for grouping together multiple key/value string pairs.
• Added Resource::NativeImage.

Improvements

• Built with Android NDK r10e
• Updated 3rd party libpng to libpng-1.6.18
• Updated 3rd party libwebp to libwebp-0.4.3
• Updated 3rd party lua to Lua 5.3.1
• Added Math::MinMax template class.
• Added ILoader::RemovePackage() and ILoader::RemoveProcessor() methods.
• Added Util::PrintToString() method (equivalent to System::CLib::PrintToString()).
• Added Graph::ITransformable methods to read Euler angles: GetRotationX(), GetRotationY() and GetRotationZ()
• Added Graph::IAnchor::GetWorldPosition() method
• Added Graph::IInstance GetReplicationNode() method
• Added Color::StringFormat enumeration for better control of how to convert a color to a string via Util::StringToColor().
• Perform rounding to the nearest integer instead of implicit floor() when querying integer values from Murl::Color.
• Added missing value getters/setters in Graph::IGenericParameter.
• Allow to query number of mip levels present in Resource::IImage.
• Added "srgb" boolean attribute in scene converter <Texture> element.
• Added IEnums::IsPixelFormatStoringLinearColorValues() function.
• Added IEnums::DEPTH_SORT_MODE_VIEW_Z enumeration value.
• Catch empty shader output after GLSL optimizer, to prevent a crash in OSX'OpenGL driver shader compiler.
• Updated GLSL optimizer.
• Misc improvements in shader translator and Util::ShaderBuilder.
• Misc improvements in shader resources.
• Added Util::IndentString() function.
• Added "includeForCondition"/"excludeForCondition" attributes in Graph::Node.
• Added Graph::ITexture::SetAutoScaleFactor() method for automatically resizing a texture to a multiple of the current output surface resolution.
• Allow frame buffers to globally share renderbuffers to save GPU memory.
• Allow attaching the same frame buffer texture(s) to multiple frame buffers.
• Added "useMipMapGeneration" attribute in Graph::FrameBuffer to automatically create a full MIP chain after rendering (texture must have "useMipMapping" set to true).
• Added "targetMipLevel" attribute in Graph::FrameBuffer to select the target texture MIP level to render to (texture must have "useMipMapping" set to true).
• Added some missing pixel format converters & scalers
• Improved quality of filtered surface scaling.
• Added possibility for gamma-correct surface scaling.
• Improved Resource::XmlShader parameterization.
• IFeatureSet: Allow to force features enabled/disabled, for debugging purposes.
• Added Graph::IListener::SetMaxDistance().
• Added length to Math::Cone.

Fixes

• Fixed Graph::Instance now creates Graph::Container nodes for replications.
• Fixed Logic::ITimeframe::WasStarted() is reported the tick after Start() instead of the same tick (which matches the behaviour of Logic::ITimeline::WasStarted()).
• Fixed a potential crash in Graph::GenericGeometry when updating vertices and/or indices
• Fixed Util::ColorToString() for hex strings.
• Fixed Graph::NinePatchPlaneGeometry problem when output size is smaller than the sum of the corner sizes.
• Fixed incorrectly added zero byte as XML entity in Util::EncodeXml().
• Fixed incorrect parsing of "timelineUnits" attribute in Graph::TimeController.
• Fixed static graph instance creation from a package when conditional sub-packages are present.
• Fixed a problem when re-initializing any of Graph::GenericParameters and related nodes.
• Fixed misc issues with Graph::GenericParameters, Graph::GenericParameter and Graph::GenericParameterGroup.
• Fixed treating an SInt32 uniform as a float in GLES2.0 renderer when setting a custom uniform variable.
• Added missing GenericResourceArrayTarget::Update() method.
• Added missing "UNDEFINED" strings for various enumerations in Murl::IEnums.
• Fixed Graph::TextGeometry line offset for multi-line strings.
• Fixed Graph::Template attribute evaluation.
• Fixed a crash in scene converter when importing an fbx scene without material.
• Fixed FBX animation import when multiple animation stacks are present.
• Fixed a crash in Graph::AudioSequence when audio source has no stream.
