Subject field(s)
  • Computer Graphics
  • Industrial Design
  • Industrial Techniques and Processes
  • Mathematical Geography
DEF

[A] mathematical or digital representation of an object as a set of planar or curved surfaces, or both, that may or may not represent a closed volume.

OBS

Surface models may consist of Bezier B-spline or NURBS [nonuniform rational B-spline] surfaces. A surface model may also consist of a mesh of polygons, such as triangles, although this approach approximates the exact shape of the model.

  • Computer Graphics
DEF

A standardized file format, called a metafile, suitable for the storage and transfer of descriptive data for creating a display image.

OBS

CGM files can contain both vector graphics information(e. g., polygons, circles, ellipses, NURBS) and raster graphics information(e. g., tile array).

OBS

NOTE - ISO/IEC 8632-1 is the International Standard for Computer Graphics Metafile.

OBS

Term, abbreviation and definition standardized by ISO.

French

Domaine(s)

English

Subject field(s)
  • Titles of Programs and Courses
  • Computer Graphics
  • Artificial Intelligence
  • Applications of Automation
OBS

Approximation of NURBS(Non-Uniform Rational B-Spline) surfaces by piecewise linear triangle meshes has important applications in manufacture, graphics, and scientific computing. In this project, we study geometric data structures and algorithms for the efficient generations of high quality meshes.

Key term(s)
  • Tessellation of Trimmed Non-Uniform Rational B-Spline Surfaces

French

Domaine(s)
  • Titres de programmes et de cours
  • Infographie
  • Intelligence artificielle
  • Automatisation et applications
OBS

L'approximation de surfaces NURBS (B-spline rationnelle non uniforme) au moyen de réseaux de triangles linéaires par morceaux a d'importantes applications dans les domaines de la fabrication, des graphiques et du calcul scientifique. Le présent projet étudie les structures de données géométriques et les algorithmes permettant la génération efficace de réseaux de grande qualité.

Key term(s)
  • Tessellation de surfaces B-spline rationnelle non uniforme
