Mesh-Based Inverse Kinematics

Example-Driven Deformations Based on Discrete Shells

Despite the huge progress made in interactive physics-based mesh deformation, manipulating a geometrically complex mesh or posing a detailed character is still a tedious and time-consuming task. Example-driven methods significantly simplify the modeling process by incorporating structural or anatomical knowledge learned from example poses. However, these approaches yield counter-intuitive, non-...

Mesh pose-editing using examples

An easy-to-use mesh pose-editing system is presented. We take advantage of both skeleton-based and example-based approaches in order to provide an intuitive way for artists to edit mesh poses. Our system automatically extracts the skeletons of the remaining examplemodels once the skeleton of a reference mesh is constructed. In our editing system the desired skeleton can be easily and naturally ...

GMDH Type Neural Networks and Their Application to the Identification of the Inverse Kinematics Equations of Robotic Manipulators (RESEARCH NOTE)

Mesh modification using deformation gradients

Computer-generated character animation, where human or anthropomorphic characters are animated to tell a story, holds tremendous potential to enrich education, human communication, perception, and entertainment. However, current animation procedures rely on a time consuming and difficult process that requires both artistic talent and technical expertise. Despite the tremendous amount of artistr...

Surgical Planning in Deformity Correction Osteotomies using Forward Kinematics and Inverse Kinematics

Patients with cerebral palsy or arthritis have deformities in lower limb which cause unstable gait or posture and pains. Surgeons perform a deformity correction osteotomy with surgical plan. But sometimes they find the unexpected angular or rotational deformation after surgery. The problems are that there is no method to predict the result of a surgical plan and also there are so many factors t...
