Page "Duke Nukem 3D" Paragraph 49

On April 1, 2009, an OpenGL Shader Model 3. 0 renderer was revealed to have been developed for EDuke32, named Polymer to distinguish from Ken Silverman's Polymost.

It allows for much more modern effects such as dynamic lighting and normal mapping.

Although Polymer is fully functional, it is technically incomplete and unoptimized, and is still in development.

As of the fifth installment of the High Resolution Pack ( released in 2011 ), the Polymer renderer is mandatory.

Another significant development of EDuke32 in 2011 is true room over room ( TROR ), where sectors can be placed over other sectors, and can be seen at the same time.

In practice, this allows for true 3-dimensional level design that was previously impossible, although the engine is still 2D.
