SDL_gpu is a C library providing high-performance, hardware-accelerated 2D rendering on top of SDL, with automatic batching, a shader API, and OpenGL/OpenGL ES backends. It offers an SDL 1.2-style API for sprites, geometry, blend states, and built-in primitive shapes.

Use cases

• render 2D sprites with GPU acceleration in C
• build a 2D game with SDL and OpenGL batching
• draw primitive shapes like lines, rects, and polygons with hardware acceleration
• mix 2D rendering with explicit OpenGL 3D calls
• apply custom shaders to 2D rendering
• load and render PNG, BMP, and TGA images with rotation and scaling

When to choose

• you want fast 2D rendering in C/C++ without writing OpenGL boilerplate
• you need automatic draw-call batching for many sprites
• you want an SDL-familiar API with shader support and blend state control
• you need to target OpenGL and OpenGL ES across desktop and mobile

When to avoid

• you need 3D rendering as the primary focus
• you want a modern renderer built on SDL3's SDL_GPU API rather than this legacy project
• you need backends beyond OpenGL/OpenGL ES such as Vulkan, Metal, or Direct3D
• you prefer a higher-level game engine with scene management
