چکیده

We present a new approach to the modeling and deformation of a human or virtual character’s arms and legs. Each limb is represented as a set of ellipsoids of varying size interpolated along a skeleton curve. A base surface is generated by approximating these ellipsoids with a swept ellipse, and the difference between that and the detailed shape of the arm or leg is represented as a displacement map. We demonstrate that the natural bending of arms and legs can be emulated using this approach, and show its effectiveness by articulating the limbs of a scanned human body and those of a virtual character.

Sweep-based Approach to Three-Dimensional Shape Deformation

We present a sweep-based approach to modeling and deformation of three-dimensional objects. We approximate the deformable parts of an object using sweep surfaces. The vertices on the object boundary are bound to the sweep surfaces and then follow their deformation. For practical applications, we apply this approach to 3D human body modeling and deformation, and then extend it to the freeform de...

Modeling the Vertical Falling Life Chute

Stretchable woven chute is a safe device for falling humans from multi-story buildings in emergencies. During the fall, the elastomeric property of the fabric, in the weft direction, causes radial forces towards the human body inside .These radial forces lead to frictional forces between the chute and the body. The falling man can reduce the falling speed by exerting outward forces via stretchi...

A comparative study on constitutive modeling of hot deformation flow curves in AZ91 magnesium alloy

Modeling the flow curves of materials at elevated temperatures is the first step in mathematical simulation of the hot deformation processes of them. In this work a comparative study was provided to examine the capability of three different constitutive equations in modeling the hot deformation flow curves of AZ91 magnesium alloy. For this, the Arrhenius equation with strain dependent constants...
