Does it help with GPU performance issues?

Absolutely. It includes patterns for triple buffering to prevent CPU/GPU race conditions and emphasizes using the Metal Validation Layer to catch API misuse and bottlenecks early.

Can I use this for visionOS development?

While it supports iOS and macOS, it specifically warns that translation layers like MetalANGLE do not support visionOS, steering you toward native Metal implementations for that platform.

Does this skill help with shader conversion?

Yes, it provides patterns for translating GLSL/HLSL to Metal Shading Language (MSL) and advises on using tools like the Metal Shader Converter for DirectX projects.

How does it handle coordinate system differences?

The skill identifies common 'upside-down' rendering bugs caused by OpenGL's bottom-left origin vs. Metal's top-left origin, providing specific code fixes for vertex and fragment shaders.

Should I use MetalANGLE or a native Metal rewrite?

MetalANGLE is ideal for quick prototyping and demos with 10-30% overhead, while a native rewrite is recommended for production apps requiring maximum performance and long-term maintenance.

Mobile Development

Guides developers through migrating legacy OpenGL and DirectX codebases to Apple's Metal framework with production-grade strategies.

概要

This skill provides a comprehensive framework for porting graphics-intensive applications to Metal on iOS, macOS, and tvOS. It assists in making critical architectural decisions between using translation layers like MetalANGLE and performing native rewrites, while offering phased migration plans that minimize risk. By highlighting common pitfalls—such as coordinate system mismatches and improper synchronization—it ensures that ported applications achieve optimal performance and stability on modern Apple hardware.
