Harlinn.Windows

This is the repository for Harlinn.Windows, a Visual Studio 2026 Solution with a wide range of useful C and C++ libraries for 64-bit Windows software development.

The code was originally published on CodeProject.com in 2021, and has a history that goes back to 2012.

    The main demo, pbrto, is a modified version of the pbrt-v4 ray-tracer that speeds up the rendering machinery. This image rendered in 1004 seconds:

    While this image rendered in 1397 seconds using the original pbrt rendering machinery:

    pbrto includes both the original rendering machinery and my modified version of the machinery, making it easy spot differences in functionality and performance.

  • Single Instruction Multiple Data (SIMD)

  • Optimized basic math functions

• Harlinn.OCI library.
  • Introduction to Harlinn.OCI
• Harlinn.ODBC library.
• Harlinn.Windows library.
• 3^rd Party Libraries
• Build instructions

.Net and C# libraries and tools:

• Harlinn.Common.Core.Net:

  • Classes for working with the Microsoft.Data.SqlClient library, providing a strongly typed interface for accessing SQL Server metadata. Used to implement Harlinn.MSSql.Tool.
  • Classes used by the C# code generated by dbxgen tool.
  • Classes used by the Harlinn.Hydrology.Net

• Harlinn.MSSql.Tool a command line tool for generating C# code for working with Microsoft SQL Server databases using the Microsoft.Data.SqlClient library.

• Harlinn.Hydrology.Net which will be, when it grows up, a .NET library for hydrology applications. This is also an LLM code generation experiment where I am using AI tools to help me write scientific code for a domain with little existing code compared to common line of business applications.
