A System for View-Dependent Animation |
|
| |
Abstract |
|
In this paper, we present a novel system for facilitating the creation
of stylized view-dependent 3D animation. Our system harnesses the
skill and intuition of a traditionally trained animator by providing a
convivial sketch based 2D to 3D interface. A base mesh model of the
character can be modified to match closely to an input sketch, with
minimal user interaction. To do this, we recover the best camera from
the intended view direction in the sketch using robust computer vision
techniques. This aligns the mesh model with the sketch. We then deform
the 3D character in two stages - first we reconstruct the best
matching skeletal pose from the sketch and then we deform the mesh
geometry. We introduce techniques to incorporate deformations in the
view-dependent setting. This allows us to set up view-dependent models
for animation.
