Garment creation continues to be the most tedious part of the virtual clothing process. In this paper, we present an easy to use sketch-based cloth modeling approach. Contours can be easily sketched on a mannequin to generate quad meshes to represent pieces of cloth already fit and draped. Typically, the clothing process depends highly on the meshing scheme that has to infer its geometry from t...

We present a method to calibrate perspective cameras from views of a deforming textured object. We proceed by finding an orthographic calibration, then enriching the camera model to include perspective effects and distortion terms. In the process, we establish the utility of using surface normals to calibrate cameras in the orthographic setting, with a proof that a metric reconstruction can be ...

this paper extends the scope of algebraic computation based on a non standard × to the more basic case of a non standard +, where standard means associative and commutative. two physically meaningful examples of a non standard + are provided by the observation of motion in special relativity, from either outside (3d) or inside (2d or more), we revisit the “gyro”-theory of ungar to present the m...

Computer-aided cloth design is one of the quite popular research themes in recent years, and the authenticity of it’s simulated result and the efficiency of simulation are two main research questions. The cloth behavior not only determines the authenticity of simulation, but also influences the efficiency of simulation. So 3D virtual clothing is simulated and rendered by the way of 2D patternin...

We present an interactive system for intuitive manipulation of dynamic cloth using multi-touch technology. The system consists of two main modes that can be toggled anytime, namely cloth creation mode and cloth manipulation mode. In cloth creation mode, the user creates pieces of cloth by drawing each desired shape directly onto the scene using simple swipe gestures. The system automatically ge...

We present a new collision resolution scheme for cloth collisions. Our main concern is to find dynamically convincing resolutions, i.e. positions and velocities of cloth elements, for any kinds of collisions occuring in cloth simulation (cloth-cloth, cloth-rigid, and cloth-cloth-rigid). We define our cloth surface as connected faces of mass particles where each particle is controlled by its int...

Cloth modeling and simulation has gained significant momentum in recent years due to advances in computational hardware and software. Cloth plays an important role not only in daily life, but also in special scenarios such as firefighter’s cloth and space suits. There are special requirements such as protection capability of the human body and mobility after the firefighters or astronauts wear ...

This paper implements efficient techniques for cloth simulation in the area of cloth model, numerical integration, collision detection and response. The whole procedure combines the accurate bending model with implicit integration and collision response. Collision response remains a serious difficulty in cloth simulation, especially with implicit integration. We propose a general scheme that in...
