basically, this is just a small article
on what is subdivision. for more details, the user is directed to caltech's
graphics web site.
Below is a series of screen shots, showing a model at different levels of tesselation.
mid level
high level
i purposely tilted the camera in the high level shot, because the jump from mid to high is not that impressive in this model.
Usually when you have a model go
from 250,000 faces to 450,000 faces, the difference is only in the "Details".
The basic shape of the model has
already been created and tesselating it further, increases detail and gives
the model a smoother look.
On the other hand, taking the jump from the low-level to mid-level is much more apparent on the topology of the surface.
Here is another example of surface
subdivision in action.
peace.
