A ybrid is basically this: a human mixed with an animal (in the ancient times they were called centaurs, fauns, chimaeras, harpys, sirens, etc.)
An "Ybrid" is not to be confused with a "Hybrid", in truth these are very different concepts, even if they share some similarities.
The word "Hybrid" has a general meaning, and denotes everything (usually plants or animals) that stems from parents that don’t belong to the same type or species.
For example a mule is the result of the cross-breeding of a horse with a donkey, or a mongrel dog is perhaps derived from a Shepeherd Dog and a Poodle.
In the offspring the features of the parents are mixed together: the hybrid inherits (for example) the eye-color from the mother, and the coat-color from the father. Other features are blended: for example the overall body shape can be an intermediate form of those of the parents.
Instead, the word “Ybrids” refers to a particular kind of creatures that are partially human and partially animal, but these features are not blended: they are rather "stitched together".
Also, Ybrids don't have "parents" (they are not generated from an animal mating with a human).
The above classification is the correct/scientific way to distinguish between Ybrids.
Another way to quickly denote a Ybrid is to put a y- before the name of the animal.
For example: a y-dog is a ybrid whose body is partially canine, a y-horse has some features of a horse etc.
This nomenclature is imprecise (because it doesn't take into account the degree of ybridization), but handy and easy to use, and therefore quite widespread.
My main problem with the 3d is to get rid of that nasty sketchupped feeling..
However Photoshop filters have the same problem: if they are used heavily (like in the above below) the result has an ever nastier "photoshopped" feeling...
