Pose Space Surface Manipulation

International Journal of Computer Games Technology, 2012
Example-based mesh deformation techniques produce natural and realistic shapes by learning the space of deformations from examples. However, skeleton-based methods cannot manipulate a global mesh structure naturally, whereas the mesh-based approaches ...

Three-Dimensional Wheat Modelling Based on Leaf Morphological Features and Mesh Deformation

Agronomy, 2022
The three-dimensional (3D) morphological structure of wheat directly reflects the interrelationship among genetics, environments, and cropping systems. However, the morphological complexity of wheat limits its rapid and accurate 3D modelling.

Tetrisation of triangular meshes and its application in shape blending

, 2016
The As-Rigid-As-Possible (ARAP) shape deformation framework is a versatile technique for morphing, surface modelling, and mesh editing. We discuss an improvement of the ARAP framework in a few aspects: 1. Given a triangular mesh in 3D space, we introduce
