libgdx-shaders

Tools to simplify shader and framebuffer usage with libGDX

libgdx-shaders is greatly inspired by an existing project and improves that project by adding gradle support and proper asset loading via the AssetLoader.

A quick example:

// loading shaders
ShaderManager shaderManager = new ShaderManager(assetManager);
shaderManager.loadShader("black_and_white", "default.vert", "blackwhite.frag");
shaderManager.loadShader("default", "default.vert", "default.frag");

// setup a framebuffer
shaderManager.createFrameBuffer("frameBuffer01");

// render the image into the framebuffer using the black and white shader
shaderManager.beginFrameBuffer("frameBuffer01");
{
    shaderManager.begin("black_and_white");
    shaderManager.setUniformf("u_blackWhite", 0.75f);
    shaderManager.setUniformMatrix("u_projTrans", batch.getProjectionMatrix());

    batch.setShader(shaderManager.getCurrentShader());
    batch.begin();
    batch.draw(region, 0f, 0f);
    batch.end();

    shaderManager.end();
}
shaderManager.endFrameBuffer();

// render the framebuffer onto a rectangle on screen
shaderManager.begin("default");
shaderManager.renderFrameBuffer("frameBuffer01", rectangle);
shaderManager.end();
