Physical based Rigging

چکیده
Computer animation has been a popular research topic since 1970s, when the first parametric facial model is proposed[0]. In the recent few years, a lot of techniques are proposed to model and animate faces like physical modelling, motion capture, mesh deformation etc. However, most of them require burden work of artists and assistance of expensive model. Rigging is one kind of the most popular techniques used in facial animation, aims to generate expression models with more details. In order to simplify this process for users and yet generate satisfying results I propose a method with spring mesh and subspace constraints. I will introduce two methods, spring mesh and expression cloning. The first is used to deform face model, while the second one is used to restrain the deformed model from being weird.

متن کاملPractical Receipt-Free Sealed-Bid Auction in the Coercive Environment
Sealed-Bid auction is an efficient and rational method to establish the price in open market. However sealed-bid auctions are subject to bid-rigging attack. Receipt-free mechanisms were proposed to prevent bid-rigging. The prior receipt-free mechanisms are based on two assumptions; firstly, existence of untappable channel between bidders and auction authorities. Secondly, mechanisms assume the ...
متن کاملA Facial Rigging Survey
Rigging is the process of setting up a group of controls to operate a 3D model, analogous to the strings of a puppet. It plays a fundamental role in the animation process as it eases the manipulation and editing of expressions, but rigging can be very laborious and cumbersome for an artist. This difficulty arises from the lack of a standard definition of what is a rig and the multitude approach...

Character rigging is a process of endowing a character with a set of custom manipulators and controls making it easy to animate by the animators. These controls consist of simple joints, handles, or even separate character selection windows.This research paper present an automated rigging system for quadruped characters with custom controls and manipulators for animation.The full character rigg...

Nowadays, a large number of countries combine formal democratic institutions with authoritarian practices. Although in these countries the ruling elites may receive considerable voter support, they often use several manipulation tools to control election outcomes. A common practice of these regimes is the coercion and mobilization of large numbers of voters. This electoral irregularity is known...
