FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package pam-native-gpu
Why PAM Native GPU
Host native GPU surfaces and compiled shaders while command submission stays outside the PHP event loop. The public API is strictly typed for PHP 8.5; expensive or frame-sensitive work stays in Rust or the platform SDK instead of crossing the application boundary every frame.
| Best for | A focused capability you can add to any PAM Native application |
| Native path | OpenGL ES · Metal |
| Application model | Composer package + generated native integration |
| Design rule | Independent module; no feed, vertical, or application template bundled |
What you can build
- Realtime visual effects and shader-driven UI
- Scientific and high-volume data visualization
- Custom renderers and GPU-accelerated creative tools
Quick start
Already have a PAM Native project? Add only this capability:
New to PAM? Follow the five-minute PAM Native setup once, then return here. Your application stays a normal Composer project with a committed lockfile.
See it in action
This package provides a horizontal GPU surface, not a canvas, 3D engine, game framework, or app template. OpenGL ES 3 executes on Android and Metal executes on iOS. PHP supplies immutable shader programs and scalar uniforms; the native render loop never crosses the PHP boundary per frame.
Shader sources are capped at 64 KiB and uniforms at 64 finite scalars. Uniforms on Metal are packed in lexicographically sorted name order. Platform support: Android API 26+, iOS 15+, PHP 8.5+, and PAM Native 0.8.x.
The render path is allocation-stable after a program revision: Android parses
uniform JSON and resolves every OpenGL location during configuration, while iOS
sorts/ packs uniforms once and reuses one Metal command queue. Neither platform
parses JSON, sorts maps, looks up shader locations, creates a command queue, or
re-enters PHP inside draw. Shader/program resources are released after both
successful and failed compilation, and diagnostic payloads are bounded.
This package depends only on PAM Native's public module and binary-wire capabilities. PAM Native UI, 3D, media, sync, and backend packages remain fully optional and independent.
