3D Modelling Tools 3 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

3D Modelling Tools 4 Cameras Virtual cameras duplicate the functions and controls of real-world cameras What controls does a real-world camera have? A. Focal length B. Field of View 3ds max v7

3D Modelling Tools 5 Camera parameters Type Focal length Depth of field Environment and clipping frames

3D Modelling Tools 6 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….

3D Modelling Tools 7 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 75 o 50mm normal lens 40 o 85mm long focus 24 o 3ds max v7

3D Modelling Tools 8 Creating cameras Target Free 3ds max v7

3D Modelling Tools 9 Create Camera From View Creates a Target camera whose field of view matches an active, Perspective viewport. 3ds max v7

3D Modelling Tools 10 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

3D Modelling Tools 11 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

3D Modelling Tools 12 Depth of Field Rendering Effect The values set in the Depth of Field parameters can blur things 3ds max v7

3D Modelling Tools 13 Clipping frame Exclude some of a scene’s geometry and view or render only certain portions of the scene 3ds max v7

3D Modelling Tools 14 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

3D Modelling Tools 15 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

3D Modelling Tools 16 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
