AMD announced that it published the complete 450-page programming guide for its Mantle 3D graphics API, and the reference API itself. The two can be accessed from here. In the run up to its GDC 2015 presentation, in a blog post written by the company's top technology exec Raja Koduri, the company said it will talk about the future of Mantle in its GDC presentation. The company intends to develop, maintain and support Mantle and its eco-system, while maintaining that it will participate in the development and support of industry-standard APIs such as DirectX 12 and GLnext (the next major version of OpenGL).
