Molten is a suite of graphics development frameworks that give you the power to transform your graphics applications and games on iOS and OS X platforms. Whether you want to move to the next-generation Vulkan API on iOS and OS X, or simply want to run your OpenGL ES 2.0 application or game faster on iOS or OS X, Molten has a graphics framework that will help you get what you want!

Molten contains the following development frameworks in a single download package:



MoltenVK is an implementation of Vulkan that runs on Apple’s Metal graphics framework. With MoltenVK, you get the performance benefits and added debugging and performance tuning capabilities of the Metal framework on iOS and OS X, while maintaining compliance with Vulkan, the new standard for open, industry-standard, next-generation, high-performance graphics API.

By building your application or game using the Vulkan API, you can run your modern graphics application or game unchanged across an entire industry of platforms and development tools.



MoltenGL is an implementation of the OpenGL ES 2.0 API that runs on Apple’s Metal graphics framework. MoltenGL provides many of the performance benefits of the Metal framework, while maintaining compliance with the proven OpenGL ES 2.0 API.

Applications built on OpenGL ES 2.0, can use MoltenGL to provide additional graphic performance, without having to abandon the familiar OpenGL ES 2.0 API, or rewrite rendering logic and shaders for different platforms.




Cocos3D is a sophisticated open-source framework for building cross-platform 3D games with Xcode and Objective-C.
