Whether for artistic or industrial purposes, 3D modelling is now a computer graphics technique widely adopted by graphic artists, designers and concept artists. It is used in a wide range of fields, from the creation of marketing images to the video games and film industries, via virtual reality, and even in more specialised sectors such as scientific and medical imaging.
What is 3D modeling?
3D modeling is the act of creating three-dimensional objects or environments that you wish to visualise on a computer. The main aim of this technique is to obtain a realistic virtual representation of these elements.
Three types of 3D modeling can be distinguished, characterised by different objectives and the use of specific software:
Surface modeling
Volume modeling
Polygonal modeling
Surface modeling
Requirement: Creation of models to accurately represent the surface of objects.
Representation method: Use of Bezier curves, NURBS patches and other mathematical surfaces to define smooth, continuous surfaces.
Who can use it? Industrialists, automotive designers, consumer product designers.
What for? The modeling of so-called « hard » models, i.e. inorganic, man-made objects (cars, household appliances, electronics).
3D surface modelling software: ALIAS, RHINOCEROS, CATIA.
Polygonal modeling
Besoin : Creation of models based on polygons, mainly for video games, animation and virtual reality.
Representation method: Use of polygons (triangles, quadrilaterals) to form 3D meshes.
Who can use it? Video game developers, 3D artists.
What is it used for? The modeling of so-called ‘soft’ models, i.e. organic objects with no rigid geometry (trees, characters, fabrics, etc.) or 3D models optimised in terms of meshing.
3D polygonal modeling software: 3DS MAX, MAYA, BLENDER.
Volume modeling
Requirement: Creation of functional mechanical parts and solid structures.
Representation method: Construction of solid three-dimensional volumes using Boolean operations (union, subtraction, intersection).
Who should use it? Industrialists, architects, engineers.
What is it used for? The modeling of models for objects requiring high precision and low flexibility, such as metal or plastic parts.
3D volume modeling software: CATIA, SOLIDWORKS, AutoCAD.
