[Bf-cycles] Micropolygon Displacement in Cycles

[Paul Geraskin]

Hi.

Houdini Mantra engine has Micropoligon rendering.
Also, Pixar's RenderMan has Micropoligon rendering too.

Micropoligon rendering has big performance against Raytrace.
I use Micropoligon rendering for fur and smoke mostly as it makes smooth
quality and it's faster about 5-7 times.

Here is simple example of rendered smoke with raytrace and micropoligon:

Micropoligon is super fast and good quality.

Also, Micropoligon renders super fast non reflected surfaces.
Here some info of houdini micropoligon:

Also, you can check Pixar's micropoligon info.
