3DS Max 7 Bible Chapter 29


Concepts What is animation? Modification of any

kind of object Light Material Camera

What can you change? Parameters

Position Rotation Scale

What parameters have been changed?

3ds max v7


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


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….

3ds max v7


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


Free v. target A Free camera has a single icon to

animate The Target camera has two

the target the camera

You can switch between camera types, changing a Free camera to a Target and back again


Camera view Make the viewport

active then press C key The Viewport

navigation controls change

Different controls for cameras than for the Perspective viewport Dolly, pan, orbit


Free camera? Try positioning a fre

camera……. Use a Target first

and then modify it to a Free

3ds max v7


Moving cameras 1 Pan

Rotates the target about the camera

Tilt or orbit Rotates a camera

about the target

3ds max v7


Moving cameras 2 Dolly

Moves the camera and/or its target along the camera's main axis

Truck Moves the camera

parallel to the view plane

3ds max v7


Animating a camera Following a moving object Moving a camera along a track Panning Orbiting Zooming Creating Animated Cutaway Views

You can animate the creation of a cutaway view by animating the location of the near or far clipping planes, or both. 3ds max v7


Following a moving object The Look-At constraint makes the

object replace the camera’s target or

Link a target camera’s target to the object

3ds max v7


Moving a Camera Along a Path Create architectural walkthroughs Car rides If the camera must bank or tilt close to the

vertical (as on a roller coaster), use a free camera

Assign the Path constraint directly to the camera object The camera follows the path, and you can adjust its

point of view by adding pans or rotate transforms This is comparable to filming with a hand-held camera.

For a target camera, link both the camera and its target to a dummy object

Assign the path constraint to the dummy object This is comparable to mounting the camera on a tripod

on a dolly 3ds max v7


Panning You can animate the pan of any

camera very easily by following these steps: Select the camera Activate the Camera viewport Turn on the Auto Key button and

advance the time slider to any frame Use the Pan button (in the viewport

navigation tools) and pan3ds max v7


Camera orbit Select the camera Activate the Camera viewport Turn on the Auto Key button and

advance the time slider to any frame Use the Orbit button (in the viewport

navigation tools) and orbit The target camera revolves around its

target The Free camera revolves around its

target distance3ds max v7


Zooming Zooming moves toward or away

from the camera’s subject matter by changing the focal length of the lens

It differs from dollying, which physically moves the camera but leaves the focal length unchanged

Portfolio 8 Use Portfolio 7 Add a target camera to your model

to follow the car Add a free camera to your car to

show the driver’s view Produce an A4 sheet with 8 small

jpegs showing the view from the 2 cameras with the car at different positions on the track


Questions List and describe three different

methods of animating a camera and recommend one for a walk through of a model

List and describe two different camera types, give and justify a choice of one for use with an avatar in a game


Impendent study Directed reading 3DS Max 7 Bible

Read Chapters 22 and 29 Portfolio 7
