A Generic Algorithm For The Generation Of Physical Movements Of Solid Systems (2000)

Didier Gillard, Jean-michel Nourrit, Laurent Lucas, Yannick Remion

This paper presents an engine for dynamic animation of solid systems based upon Lagrangian equations. The goal is to animate in an automatic way any scene composed with rigid objects defined in...

3D Metamorphosis For Voxel-Based Modeling In Biomedical Imaging (2000)

Laurent Lucas, Didier Gillard, Yannick Remion, Nol Bonnet, Rue Clment Ader

To perform computer animation, it is often necessary to interpolate between existing data, i. e. to fill the gap between two stages of the evolving structure. The metamorphosis technique is one of...

A Generic Algorithm For The Generation Of Physical Movements Of Solid Systems (1999)

Didier Gillard, Jean-michel Nourrit, Laurent Lucas, Yannick Remion

This paper presents an engine for dynamic animation of solid systems based upon Lagrangian equations. The goal is to animate in an automatic way any scene composed with rigid objects defined in...

An Integrated And Efficient Voxel-Based Rendering System: From Discrete Skeleton Shape Descriptor To Implicit Surface Visualization (1999)

Stphanie Prvost, Laurent Lucas

This paper presents a new algorithm of volume rendering based on a dual representation of data in order to improve at the same time the image generation speed and its quality. Two shapes descriptors...

The Three-dimensional Study of Chromosomes and Upstream Binding Factor-immunolabeled Nucleolar Organizer Regions Demonstrates Their Nonrandom Spatial Arrangement during Mitosis

Klein, Christophe, Cheutin, Thierry, O’Donohue, Marie-Françoise, Rothblum, Lawrence, Kaplan, Hervé, Beorchia, Adrien, ...

The volumic rearrangement of both chromosomes and immunolabeled upstream binding factor in entire well-preserved mitotic cells was studied by confocal microscopy. By using high-quality...

Electron Tomography of Metaphase Nucleolar Organizer Regions: Evidence for a Twisted-Loop Organization

Heliot, Laurent, Kaplan, Hervé, Lucas, Laurent, Klein, Christophe, Beorchia, Adrien, Doco-Fenzy, Martine, ...

Metaphase nucleolar organizer regions (NORs), one of four types of chromosome bands, are located on human acrocentric chromosomes. They contain r-chromatin, i.e., ribosomal genes complexed with...
