The main control is the micropolygon length.

Image Removed

By default, it is expressed in pixels and a micropolygonlength of 1 (the default) means that every micropolygon will be approximately 1 pixel wide.
If you don't want the tesselation to change dynamically, you can set it in object or world space or define a dicing camera.

Tip
We recommend disabling "raster-oriented dicing", unless you see some artefacts.

This is a creased displaced catmull-clark subdivision surface.

Increasing the micropolygon length is equivalent to making the object's size smaller in the image.

When the object is large, it is finely tesselated into milions of micropolygons.
When the object becomes smaller than a pixel, only the control mesh remains.

This works a bit like an automatic level of detail.

Model detailing

Often, it is better to rely on displacement and bump mapping to add details.
