Zig‑SDL3‑GPU‑Programming

A cross-platform Zig demo showcasing GPU rendering with SDL3, SIMD math, and SPIR‑V shaders.

Features

• Cross‑Platform Window & GPU Context: Uses SDL3 (via zig-sdl3) to create windows and GPU devices.
• SIMD‑Optimized Math: Uses zmath for fast vector and matrix operations.
• Texture Loading: Uses zstbi to decode textures (PNG, JPEG, HDR).
• Shader Pipeline: Compiles GLSL to SPIR‑V at build time using glslc.
• Frame Rate Control: FpsManager.zig for accurate timing.
• Single‑Command Build & Run: zig build run.

Requirements

• Zig ≥ 0.14.0
• Vulkan SDK (provides glslc)
• C Compiler Toolchain
• Git

Installation & Usage

git clone https://github.com/stark26583/Zig-SDL3-GPU-Programming.git
cd Zig-SDL3-GPU-Programming
zig build <name>
