CAD Modelling and the Video Game Industry.
Before CAD modelling, pre-1995, "3D" games consisted of 2-dimensional bitmap based sprites as characters or objects animated in a 3D map-based background. The 2D sprite was disguised as 3D by having it always facing the camera. This technique is used in old games such as Duke Nukem 3D, Doom and Quake I. Having a sprite based on bitmap, however, produced poor quality images when you got the camera too close to the object. This is because bitmaps are 256 limited colours, pixelated (dotted or blocky) images used for computer painting. They become blocky and hard to see when zoomed in or resized. CAD and CAD modelling use technical drawing techniques. The difference between computer painting and drawing is: .
Painting involves changing the colours of pixels using a painting tool or program, like Microsoft Paint. You can apply colours gradually, with soft edges and transitions, and manipulate individual pixels using filter effects. However, once you apply a brush stroke, there is no easy way to select the entire brush stroke and move it to a new area in the image.
Drawing, on the other hand, involves creating shapes that are defined as geometric objects (also called vector objects). Like, if you draw a circle using a circular tool, the circle is defined by a specific radius, location, and colour. You can quickly select the entire circle and move it to a new location, or you can edit the outline of the circle to distort its shape. .
Working with shapes or 3D models provides two advantages:.
o Shapes or models are object-oriented--you can quickly select, resize, and move a shape, and you can edit a shape's outline (called a path) and attributes, such as line weight, fill colour, and fill style. .
o Shapes are resolution-independent--they maintain crisp edges when resized, printed to a PostScript printer, saved in a PDF file, or imported into a vector-based graphics application, like a video game.
This reference guide describes the general principles of working with AutoCAD and how they can be applied to all the leading CAD programs. ... Because this manual will only cover the general design program functions, readers should not expect complete knowledge of CAD software. Most of the information in this manual was pulled from several CAD text as well as questionnaires from current graphics majors....
Project Scope & Current Evaluation Goals Supported by CAD Initiative: In converting to a completely independent CAD system, there are a few aspects of operation which would be greatly improved. ... Using a CAD system, part designs could be received in an electronic format such as a math model. ... CAD Vendors & Hardware Suppliers: Upon observing the various systems used by several customers and suppliers, the major CAD vendors worth consideration have been identified. ... Using a CAD system to perform a volume calculation, the answer would be definitive. ... Solution Evaluation & R...
Computer Aided Design An overview of Computer Aided Design (CAD). INTRODUCTION The aim of CAD is to apply computers to both the modeling and communication of designs. ... In principle, CAD could be applied throughout the design process, but in practice its impact on the early stages, where very imprecise representations such as sketches are used extensively, has been limited. ... So far, CAD systems have been described in very general terms. ... CAD systems are no more than computer programs (although often large and complex), perhaps using specialized computing hardware. ...
Entering this semester I had currently only used any CAD software for one semester. ... Being a beginner when it comes to CAD, there were also a few things I did not know or did not like about the IDEAS software. ... It teaches the 2D and the 3D aspects of CAD systems. ...
One computer serves as the telephone system, called Vesta, and the other computer is the data input system, which is called CAD (computer aided dispatch). The CAD system is used to enter request for police service from the public. Depending on the type of phone (land-line or cell) used to place the call for police service, information such as address and name can be automatically input on the CAD screen. ... On the radio side of the room each position has four computers; Vesta, CAD, CAD1 and the radio. The Vesta and CAD are the same as the 911 equipment. ...
Computer-aided design (CAD) is used frequently in engineering. ... At first CAD programs only performed less complicated automated drafting projects. ... As microelectronics devices have become smaller and more complex, CAD has become an especially important technology. The introduction of CAD's have lowered costs and shortened the design cycle in many industries. The understanding of CAD's and similar programs are a vital component to any engineering career. ...
