A high-level abstraction for graphics hardware programming

Currently available graphics hardware has become programmable. However, this programmability is still offered at a very low abstraction level, usually based on a specialized assembly language, and is difficult to use. To overcome this problem, we present a simple programmable pipeline abstraction. Our proposal is built over the Lua programming language. The application programmer writes a Lua code that, when executed, generates the equivalent assembly code to be loaded by the hardware. We compare our proposal to other recently published ones or still under consideration.
