3DF 28.20

WARNING. We are planning to remove support for Android x86 (32-bit) and v7 by the end of the year. If you are still supporting these platforms and need advice about how to proceed, please contact TS3D Support to discuss your options.

Library Compatibility Information

Library Name	Version	Notes
DGN Direct	4.2
HOOPS Communicator	2022 SP1
HOOPS Exchange	2023 SP2 U1
HOOPS Publish	2023 SP2 U1	Requires support for SSSE3 instruction set.
.NET Framework	4.5	Required for VS 2017 libraries and samples.
.NET Standard	2.0	Required for VS 2019 libraries.
.NET Core	5.0	Required for VS 2019 samples.
Parasolid	32.0.x
Qt	5.12.7	Visualize is compatible with Qt 5.4 on OSX
RealDWG	2019	RealDWG 2019 is compatible with Visual Studio 2015 Update 3 and Visual Studio 2017 Update 2
SketchUp	2023	64-bit Windows only. Requires Visual Studio 2019 Redistributable.

Enhancements

Codegen debugging. Codegen debugging utility is more reliable at producing output for “large” and “very large” execution paths.

Transparency rendering option. A new rendering option for transparency bias definition has been added. Two options are available: “normal” and “msaa”.

Custom vertex shaders. Specific behaviors such as custom colors and interpolation can be applied to lines and markers using custom vertex shaders.

Functional Changes

.NET changes. Visual Studio 2019 libraries are now shipped in .NET Standard 2.0, allowing customers to run their applications from .NET 4.5 to .NET 6. Sample applications as delivered are set up to run using .NET 5.

Marker color. Marker custom glyph color is inherited from segment when using SetNormalColor on the glyph and SetExplicitColor on other glyphs.

Hardware accelerated text. Highlighted text now uses the hardware acceleration path for all types of text, resulting in improved rendering performance.

Postscript export. Memory usage reduced when saving PostScript files.

Include paths. Memory usage reduced when using include paths in the segment tree.

Text spacing. Text aspect ratio and spacing is now slightly different due to a correction in the way FreeType fonts are handled.
