Genesis Engine is an open source graphics engine made from scratch with OpenGL and C++, by 5 Multimedia Engineers for our final year project, Inspire.

This engine was designed and programmed for low-end devices (it has proven good performance in a Intel Celeron 3000 series processor with 2 GB for RAM, where 700MB are reserved for video memory, no graphics dedicated card) . It's main features are:

• Simplicity.
• Flexibility.
• Support for efficient resource handling.
• Support for post-processing effects.
• Cel-shading.
• 2D graphics and Billboards.
• Optimization techniques such as Frustrum Culling and dynamic Level of Detail (for static meshes and even animations).
