Graphic Design

• Before Digital Media, all graphic design was done using pen, paper and ‘wet’ photography.

• What now takes an hour, used to take a day or more to prepare.

• How long ago – about 15 years.

Professional pens cost about $9.00 each.

You need a lot of pens to create realistic drawings!

Graphic Designers used to hand draw images using these pens to show their clients. The might produce something like these in about 2 hours.

Using designer textas is a skill they learned by attending art college for about 5 years.

Digital Graphic Design

• PAINT programs are used to create …• RASTER (BITMAP) graphics made up of

many pixels.• Photos from a digital camera are BITMAP• DRAW programs are used to create …• VECTOR graphics. Made mathemetically

by the computer• Computer Aided Design (CAD) is

VECTOR

Where do you see VECTORS?

• Flash and Shockwave games are VECTOR graphics. The computer works out how to draw and colour the lines.

• VECTORS are faster to animate, faster to colour and are smaller in file size than ‘bitmaps’.

• Computers are great at figuring out VECTORS, they love doing MATHS.

MODELLING & RENDERING

• Digital Media is used to MODEL and RENDER objects, buildings people and things.

• MODELLING is making a wire frame skeleton of an object in a computer.

• This is done by plotting points and shapes in three dimensions.

• Once this is done you can MANIPULATE the object, turn it, view it etc.,

RENDERING

• Rendering in the process that computers used to put TEXTURE and LIGHT onto a computer model to make it realistic.

• More realistic=more processing/time

• Models can also be animated, this means there are 15-24 renders to be done each second. BIG computers are needed.

• RENDERING creates light and shadows

Like the idea of Modelling?

• Its quite easy to do, once you start to see things how a computer does

• You can create simple shapes easily

• You can ‘render’ easily

• It’s fairly quick to learn the basics

• A free modeller is called BLENDER

• 3D STUDIO MAX is more professional – and expensive!

Class Task

• Using the Internet to research images and information …

• Create a logo for a coffee company called “Beach-Chic”

• Makes towls, beach wear, sunnies that are ‘up market’ and expensive.

• Upload your logo in a POWERPOINT document.
