Given several regular shapes from different categories (with regular structure), our system can iteratively generate sets of monsters with abnormal structure as revealed by the inset on the right bottom side of each model.
Some monster examples designed with our system.
For each session, we show the input shapes and randomly selected shapes
from three generations and background sets.
Abstract
Monsters and strange creatures are frequently
demanded in 3D games and movies. Modeling such kind of objects calls for
creativity and imagination. Especially in a scenario where a large
number of monsters with various shapes and styles are required, the
designing and modeling process becomes even more challenging. We present
a system to assist artists in the creative design of a large collection
of various 3D monsters. Starting with a small set of shapes manually
selected from different categories, our system
iteratively generates sets of monster models serving as the artist’s
reference and inspiration. The key component of our system is a
so-called creature grammar, which is a shape grammar tailored for the
generation of 3D monsters. Creature grammar governs the
evolution from creatures with regular structures gradually into monsters
with more and more abnormal structures through evolving the arrangement
and number of shape parts, while preserving the semantics prescribed as
prior knowledge. Experiments show
that even starting with a small set of shapes from a few categories of
common creatures (e.g., humanoids, bird-like creatures and quadrupeds),
our system can produce a large set of unexpected monsters with both
shape diversity and visual plausibility, thus providing great support
for the user’s creative design.
