A pure Go wrapper for Microsoft's Direct3D9 API, enabling Windows game development in Go.
d3d9 is a pure Go wrapper for Microsoft's Direct3D9 graphics API that enables Windows game development using Go. It provides a complete interface to Direct3D9 functionality without requiring CGo, allowing developers to create graphics applications and games with Go's tooling and simplicity.
Go developers who want to create Windows games or graphics applications using Direct3D9, particularly those participating in game jams or building 2D/3D rendering projects.
Developers choose d3d9 because it provides a complete, CGo-free Direct3D9 implementation with Go-friendly APIs, making Windows game development more accessible in Go while maintaining compatibility with existing Direct3D9 knowledge.
Direct3D9 wrapper for Go.

No CGo dependency simplifies compilation and cross-compilation to Windows, as noted in the README's installation section, making distribution easier.
Wraps the entire Direct3D9 API with Go-friendly naming conventions, allowing developers to leverage existing Direct3D knowledge without C++ overhead.
Provides idiomatic Go methods like GetFloat32s and SetFloat32s for buffer and texture data, reducing the need for unsafe pointer manipulation as described in the Usage section.
Returns standard Go errors instead of HRESULT codes, simplifying integration with Go's error patterns and making debugging more straightforward.
The README admits missing functions for reading texture data or updating sub-rectangles, requiring manual workarounds for advanced texture operations.
All Direct3D9 calls must be made from a locked OS thread, complicating application architecture and limiting concurrency, as enforced in the init() code example.
Direct3D9 is an outdated graphics API; developers needing modern features like shader model 5.0 or better performance optimizations will find it inadequate.
Inherently tied to Windows via d3d9.dll, making it unsuitable for any cross-platform development, which is a significant constraint for broader adoption.
