    Space3d

    Space3d

    C# graphics library used for 3D modeling, built with OpenGL/OpenTK

    The Graphics Library is built on top of OpenTK, the C# library that wraps OpenGL. The intended clients are technical and engineering graphics applications that require three-dimensional visualization tool. The implementation draws a scene on separate working thread, optionally, the thread-updater may be invoked. The Space3d Library uses Recursive Composition design pattern. The hierarchy by reference, built into the component, plays a dual role in modeling three-dimensional space: first, it provides a control over a lifetime of the object cluster; second, it mirrors a subordination of the object coordinate systems. The project libraries are built with Visual Studio, using .NET Framework 4.7.1. To test the graphics capabilities, compile and run the GraphicsTest solution. To test the Space3d Library, compile and run the Space3dTest solution.

    SqlClientDAC for Delphi

    A feature-rich and high-performance data access components for MS SQL

    SqlClient Data Access Components (SqlClientDAC) is a feature-rich and high-performance library of components that provides native connectivity to SQL Server from Delphi. SqlClientDAC-based applications connect to SQL Server directly through the ADO.Net SqlClient, which is a .NET Framework Data Provider for SQL Server. SqlClientDAC is designed to help programmers develop faster and cleaner SQL Server database applications. SqlClientDAC uses its own protocol to communicate with SQL Server. SqlClientDAC is lightweight and performs well because it is optimized to access a SQL Server directly without adding an OLE DB or Open Database Connectivity (ODBC) layer. SqlClientDAC, a high-performance and feature-rich SQL Server connectivity solution, is a complete replacement for standard SQL Server connectivity solutions and presents an efficient native alternative to the Borland Database Engine (BDE) and standard dbExpress driver for access to SQL Server.
