Research direction

The issue names no files, tests, or entry points. Start by reviewing the existing SIMD architecture support and project guidance for platform additions, then determine whether WebAssembly v128 support and Rust bindings are separate scopes. Done would require an agreed scope and acceptance criteria for both requests.

Description

conformance

DirectXMath supports SIMD on architectures such as SSE2 but does not support WebAssembly SIMD intrinsics using the v128 type.
As a header-only library that compiles with any standard C++20 compiler, I successfully compiled it with Clang targeting WebAssembly but found no intrinsic support for WebAssembly SIMD.

I prefer DirectXMath over other libraries (such as GLM) because it is released under the MIT License, supports major SIMD instruction sets, and offers useful functions for software rendering.

My main use case for DirectXMath is software-based rendering (rasterization and ray tracing) targeting outputs such as:

Win32 (GDI)

Direct2D

HTML Canvas via WebAssembly

BMP files

Could you consider adding support for WebAssembly SIMD intrinsics using the v128 type?
Also, with Microsoft’s recent focus on Rust, are there any plans for official Rust support or bindings in DirectXMath?

Thank you for your consideration.
