Designing (extremely large topic – all what you see around you is designed via computers graphics CAD CAM)

Entertainment (movies, games, virtual environments)

Science, scientific visualization Advertising and commerce Education

What is modeling?

Adding 3D objects to the 3D scene, what is controlled by modeling application and you. The 3D environment/object is modified by changing the objects/environment parameters

“The spatial description and placement of imaginary three-dimensional objects, environments, and scenes with a computer system is called modeling. “

3D models can be done in many ways (temple based, program guides, laser measurements…), in this course we use 3D modeling tool (3D Studio Max)

14

Before you start modeling, please read this list!

Sit down and think! Think more! Select measurement units and draw a draft sketch

about your object with main dimensions Select coordinate axels direction Select Origon location (world coordinate) Models and objects, objects parts naming rules If there are more than one person to work on same

modeling project, DOUBLE CHECK that same rules are used

Modeling; working space, scene

You can setup cube, where all modeling will happened, can be eliminate outside geometry = you can see it saves memory and helps to see objects

You can modify the scene many ways = more effective way to work (hide objects, using cutting planes, display only part of model hierachy)
