This week Cameras

Camera basics Using cameras Camera parameters Viewing through a camera

3DS Max 7 Bible Chapter 26

Model A is due on Friday


Cameras Virtual cameras duplicate the

functions and controls of real-world cameras

What controls does a real-world camera have?

A. Focal lengthB. Field of View

3ds max v7


Camera parameters Type Focal length Depth of field Environment and clipping frames


Focal length The distance between the lens and

the light-sensitive surface Lens size

28mm wide angled lens 50mm normal lens 85mm long focus and more….


Field of view Field of View

the width of your view as an angle with its apex at your viewpoint and the ends at the sides of the view

Relates to the lens size 28mm wide angled lens

75o

50mm normal lens 40o

85mm long focus 24o

Creating cameras Target Free

3ds max v7


Create Camera From View Creates a Target camera whose field

of view matches an active, Perspective viewport.

3ds max v7


Activity Create an array of 9 cubes

Work in metres Note the sizes and distances

Add a camera Change a viewport to a camera Alter the lens size

Normal Wide angled Telephoto


Depth of Field Simulates the

natural blurring of foreground and background scene elements Related to the

aperture setting on a real camera

3ds max v7


Depth of Field Rendering Effect The values set in the

Depth of Field parameters can blur things

3ds max v7


Clipping frame Exclude some of

a scene’s geometry and view or render only certain portions of the scene

3ds max v7


Activity Working with your set of cubes:

Position of four cameras as follows: Bird’s eye Overhead Worm’s eye Normal

Export as VRML and view Alter the depth of field Alter the clipping planes


Questions You have been asked to model a race

track Describe the difference between Free and

Target cameras, giving an example of how you would use both

Give three different positions for static cameras and lens sizes to create different effects, discuss the effects and justify your choice


Portfolio 6 A word document with 4 jpegs, each

with a view from a different camera of a scene with 12 cubes : One to demonstrate a wide angle lens One to demonstrate a telephoto lens One to demonstrate clipping One to demonstrate depth of field
