About us

AB4D is a limited liability company that develops software libraries that can be used to add advanced 3D visualisation to .Net applications.


The development of the products started in 2006 when the first beta version of WPF (Windows Presentation Foundation - technology to develop advanced user interfaces in Windows-based applications) became available. For me, the most amazing feature of WPF was that it could show 3D objects in an application. My passion for 3D graphics led to the development of the first product, the Reader3ds library. It can import 3D objects from 3ds files into WPF 3D objects.

In 2009 the first official version of Ab3d.PowerToys library was released. It provided many helper tools for 3D graphics in a WPF application.

Later, products for 2D graphics for WPF and Silverlight were developed (ReaderSvg, ReaderWmf and ZoomPanel). Those products for 2D graphics can still be purchased, but after 2021 they have only limited support because the company is now fully dedicated to 3D graphics.

In 2015 the first version of Ab3d.DXEngine library was released. This library significantly enhanced the capabilities of WPF 3D graphics and Ab3d.PowerToys library. The introduction of DirectX 11 rendering brought a huge improvement in speed and visual quality, inspiring us to continue pushing the boundaries of what our products could achieve.

In 2023 the support for 3D graphics became cross-platform by the introduction of Ab4d.SharpEngine. Unlike the previous products, which were limited to Windows OS, the new Ab4d.SharpEngine can now run on Windows, Linux, macOS, Android, and iOS.

This exciting journey brings us to the time when it is possible to easily show 3D graphics on almost all possible form factors, from tiny embedded Linux devices to high-end PC and Macs.
