Started implementing the triangle rendering based on geometry shader
Triangle rendering ported
Started to port A-Buffer pass. Non-functional code.
Added randomwrite targets to the abuffer pass. still non-functional.
A-Buffer pass is working now, currently working on K-Buffer pass.
Stencil bug fixxed, KBuffer implementation started.
Inspecting A-Buffer pass. Coverage computing is not working.
Patched simulation bug. only the first vertex in a strand was marked as immovable, which resulted in randomly moving hairs in the pony tail. Still inspecting a-buffer pass why coverage computing is not working
More A-Buffer inspecting. Still no idea whats going on :/
A-Buffer pass working. Only K-Buffer Sort and Draw pass is missing now.
