SDL_gpu is a C code library for making hardware-accelerated 2D graphics easy.

SDL_gpu is licensed under the terms of the MIT License.
See LICENSE.txt for details of the usage license granted to you for this code.

A good way to use this documentation is to start on the Modules page.

FEATURES

High performance (it automatically collects and submits batches instead of separate draw commands for each sprite and redundant state changes) Shader API Arbitrary geometry rendering (triangles) Can be integrated with explicit OpenGL calls (mixed 2D and 3D) Full blend state control Built-in primitive shapes (points, lines, tris, rects, ellipses, polygons, even arcs) Uses a style familiar to SDL 1.2 users Compatible with either SDL 1.2 or 2.0 Loads BMP, TGA, and PNG files via stb-image Rotates and scales about the center of images, making reasoning about the resulting corner coordinates more obvious (adjustable via anchor settings)

LATEST SOURCE

SDL_gpu is hosted on Github (https://github.com/grimfang4/sdl-gpu). You can check out the latest version of the source code with Git:

git clone https://github.com/grimfang4/sdl-gpu.git sdl-gpu

DEPENDENCIES

SDL 1.2 or SDL 2.0 (www.libsdl.org)
A rendering backend
Currently implemented: OpenGL 1.1, OpenGL 2.0, OpenGL 3.0, OpenGL 4.0, OpenGL ES 1.1, OpenGL ES 2.0, OpenGL ES 3.0

BUILDING

You can see automated build status at the project page on Travis CI:

[Build Status]

Automated builds will soon be available on the Github.io page.

SDL_gpu uses CMake (www.cmake.org) to coordinate the library build process. CMake is available as a GUI program or on the command line.

For Linux/UNIX systems, run CMake in the base directory:

cmake -G "Unix Makefiles"
make
sudo make install

For Linux/UNIX systems, changing the default installation directory can be done like so:

cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/usr

For Windows systems, you can use cmake-gui and select appropriate options in there (warning: cmake-gui is messy!).

INCLUDING / LINKING

Add the include for SDL_gpu.h to your sources. Link to SDL2_gpu (libSDL2_gpu.a) or SDL_gpu (if you use the old SDL 1.2).
