Assignment 6

2D and 3D CAD

Introduction

Computer graphics are pictures and films created using computers. Usually, the term refers to computer-generated image data created with the help of specialized graphical hardware and software.

2D CAD :- 2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies such as typography. In those applications, the two-dimensional image is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred because they give more direct control of the image than 3D computer graphics, whose approach is more akin to photography than to typography.

3D CAD:- 3D graphics, compared to 2D graphics, are graphics that use a three-dimensional representation of geometric data. For the purpose of performance, this is stored in the computer. This includes images that may be for later display or for real-time viewing.

RASTER AND VECTOR IMAGES
There are two main type of image files: Raster and Vector. Raster images are created with pixel-based programs or captured with a camera or scanner. They are more common in general such as jpg, gif, png, and are widely used on the web. Vector graphics are created with vector software and are common for images that will be applied onto a physical product. Also used in CAD, engineering, and 3D graphics which we do not provide information nor services for.

2D CAD


In this assignment I used Adobe Photoshop for raster and Adobe illustrator for vector CAD.I made the logo and postage stamp for the 50th Convocation of IIT Delhi.


I used the pen tool,paintbrush tool,shapebuilder,gradient tool,ellipse tool,etc to arrive at the final model.













3D CAD


In this assignment I used Fusion 360 to model a wrench.


Step1: Open Fusion 360 and get familiar with the interface and get to know the various tools and their functions.




Step2: Make the 2D sketch of the model.




Step2: Complete the 2D model.




Step2: EXtrude the 2d sketch to make it 3d.




Step2: Render the 3d model in rendering softwares to get a realistic view.
