SDL_GPU Library Released for High-Performance 2D Graphics Painting in SDL3

Introduction to SDL_GPU

SDL_GPU is a new minimal, single-header library designed for high-performance 2D graphics painting within SDL3 applications. It provides core functionalities for rendering graphics elements efficiently.

Port from sokol_gp

The library is a direct port of sokol_gp to SDL3. Unlike sokol_gp, which relies on sokol for internal resource management, SDL_GPU operates at a lower level and includes its own resource management system, similar to sokol's approach.

Core Functionalities

SDL_GPU supports drawing various graphical primitives, including rectangles, and handles sprites and blendmodes. It also provides APIs for error handling, image creation and management, and shader creation, allowing developers to integrate custom rendering effects.

Example Usage

Developers can acquire a command buffer, begin a frame, clear the screen, and draw shapes like filled rectangles using functions such as SDL_AcquireGPUCommandBuffer, SDL_GPBegin, SDL_GPClear, and SDL_GPDrawRectFilled. The library also allows rendering to a swapchain or a texture, with commands flushed via SDL_GPFlush and submitted using SDL_SubmitGPUCommandBuffer.
