Enhancements

• CATDrawings can now be imported via hio_exchange.

• Our ambient occlusion algorithm has been enhanced to provide better visual results. The new algorithm is only supported on Windows with the dx11 or opengl2 drivers at this time; otherwise, Visualize defaults back to its previous ambient occlusion algorithm. As part of this upgrade, the Set_Driver_Options() function has a new option called Set_Driver_Options_post_world_scale, and the Set_Driver_Options_ambient_occlusion option has a new suboption called Set_Driver_Options_ambient_occlusion.

• Visualize’s importers now offer a choice on whether to import attributes using double or single precision. This feature is implemented with a new member variable in the HInputHandlerOptions class, m_attributePrecisionMode. In addition, a flag has been added to HInputHandlerOptions called m_generatedDouble as well as a function in HBaseModel called getContainsDouble(). These indicate whether double-precision attributes were added to the scene during import (as a reminder, precision can be converted with Convert_Precision). If you choose to import a file using the FLOAT_IF_SAFE, RETAIN_AS_IS or FORCE_DOUBLE option, it is possible that the resulting scene will contain double precision information. Please note that no part of MVO is guaranteed to work on a scene which contains double precision geometry or attributes.

• Significant improvements have been made to the algorithm that assembles capping geometry for cutting planes.

• Functions have been added for adding shape backgrounds for text annotations and anchored leader lines. Please see Define_Shape and Insert_Text_Leader. In addition, new options have been added to the Set_Text_Font() function for setting background shapes and defining line options (see the “background” and “decoration style” options).

• Visualize has upgraded to the ICU font layout version 57.1.

Functional changes

• Support for 32-bit CentOS and Ubuntu has been discontinued.

• Support for Visual Studio 2012 has been discontinued.

• A debug Set_Driver_Options_debug is now required for D3DImage usage with the dx11 driver in the wpf_image sample project. Please note that it will affect dpi-sensitive elements (like text and markers) because Visualize will treat such driver instances more like a physical window rather than a virtual off-screen window with a hard-coded dpi. See Set_Driver_Options() for more details on debug bit masks.
