3D MODELING BASICS
3D Modelling describes about any product or items in a particular form that appears to be physically present with the designated structure. Generally it appears to be flat to human eye which can be represented in its three dimensions width, length and height. They are represented in different sectors right from engineering to manufacturing to digital animation. Initially computer graphic are used in 1960 for scientific and emerging purpose then comes CGI artistic expression in the same year. 3D modelling helps in creating 3d objects whereas CAD models are visually presented as two dimensional objects using 3d rendering and visualising techniques. 3D modelling methods are represented through these 3 general methods.
DIGITAL SCULPTING METHOD: In this method artist uses computer and create virtual image and in this there is use of software that offers tools to push, pull, smooth, grab, pinch or otherwise manipulate a digital object as if it were made of a real-life substance such as clay.
CURVE MODELING: Another type of modeling that depends on curves to generate surface geometry. Curve modeling can be both parametric (based on geometric and functional relationships) or free form, and it count on NURBS (no uniform rational B-spines) to describe surface forms.
Code-driven modeling: This is a rising area of modeling where geometry is generated separately based on conditions set in place by the designer. This type of modeling is exceptionally for 3D printing as it can be used to generate 3D structures that can’t be mass-produced through any other means.
Three-dimensional model that shows a picture or item in a method that seems to be physically present with a nominated structure. Essentially, it permits items that seemed to be flat to the human eye to be display in a system that allows for various dimensions to be represented. These dimensions include width, depth, and height.
