Quantum Engine is an cross-language 32bit native code compiler with an advanced 2D game engine for PC’s running Microsoft Windows® and uses Direct3D® for hardware accelerated rendering. It’s robust, designed for easy of use and suitable for making all types of 2D games and other graphic simulations. Your code can compile to a stand-alone EXE and/or to dynamic loadable compiled units (runtime packages). The core game engine consists of a high-level object oriented game application framework with a plethora of classes and routines to allow you to rapidly and efficiently develop your graphics simulations. There is support for surfaces, textures, sprites, audio, streams, archives, configuration files, render targets, swap chains, databases and much more.

Quantum engine is free of charge for freeware projects but if you plan to sell them then you need to buy license for the game.

Cal3D

Cal3D is cross platform and skeletal based 3d character animation library. It is written in C++, and it is portable to multiple operating systems.

It supports combining animations and actions through a “mixer” interface, and work is currently underway to integrate morph targets (interpolating between one mesh and another, using the same vertex sequence) easily into the system.

For more information and download you can try official website of Cal3D here.
