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.
