LFB

The layered fragment buffer (LFB) demo framework. An updated library from the original we introduced in the OpenGL Insights: Efficient Layered Fragment Buffer Techniques book chapter.

Includes factory style deep image construction, storage and access implementations, and attempts to abstract the LFB implementation in both C++ and GLSL. These include:

• LFB_TYPE_B basic (3D array)
• LFB_TYPE_LL linked lists
• LFB_TYPE_PLL paged linked lists (Crassin spinlock)
• LFB_TYPE_L linearized (prefix sum scan)

This project uses pyarlib for shader and GL buffer management.

The most straight forward application is order independent transparency, for which a demo application is also provided. The techniques included there are from Fast Sorting for Exact OIT of Complex Scenes.
