An Algorithm for Voxel Apparel Synthesis for the Visible Female
Our Contribution
We present a novel 3D volumetric apparel modeling approach that is suitable for the visible
female.
Voxel Apparel Modeling
Method
This section describes the voxel apparel modeling algorithm for the visible human data. The
steps involved are:
- Load the visible human as a volume.
- Select control slices.
- Determine boundary points on control slices.
- Solve for control points to define the NURBS surface of the apparel.
- Transform control points to obtain deformation of apparel.
- Voxelize NURBS to obtain voxel representation of apparel.
- Integrate apparel for the visible female.
The input data available is the visible female and it is
loaded to the
system as a single volume buffer. An interactive discretization of the model is done to obtain
the control slices
which represent a slice through the female body. Since it is logical to transform the apparel to
provide a natural
appearance, the control points have been transformed to facilitate the physical motion of the
apparel. The critical
part is to interpolate the control points for the NURBS surface. An efficient NURBS
voxelization algorithm is used
to obtain the volumetric apparel.
Two issues that
complicate the apparel modeling are:
- A digitization of the human is required to generate the patches.
- A common problem noticed with existing methods, where the collision test with
arbitrary bounding surfaces is time consuming and not accurate.
However a voxel
modeling scheme solves the above two
problem as follows:
- Since the visible human is available in digitized form, it is quite easy to get the digital
data for the cloth patches.
- Collision detection since every voxel is available, it is simple to compute the collision
of the apparel on the human.
Hence we propose a voxel based apparel modeling system
that overcomes the drawbacks of traditional apparel modeling.
Results and Discussion
The algorithm has been successfully tested with the visible female dataset to design complex
apparel designs. The
apparel design has been found suitable for designing dress that fits both the upper and lower
parts of the body. The
initial control slice specification of the visible female was obtained interactively from the
original visible female
data set.
