Week 6 Boolean and Meshes
3D Modelling Tools 2
Last week Storyboards
Planning your model Sketches Resources
2D to 3D Have you started researching yet for
your Model A?
What have you done?
3D Modelling Tools 3
This week Compound objects
Boolean Mesh modelling
Working from a graphic Working with sub-objects
This is the last lecture on pure modelling Only an introduction
Up to you to develop and improve your skills
3D Modelling Tools 4
3D Booleans Powerful sculpting tools Multiple objects Usually destructive
3ds max v7
3D Modelling Tools 5
Union Boolean Union or addition
The intersecting or overlapping portion of the geometry is removed.
3ds max v7
3D Modelling Tools 6
Intersection Boolean Intersection
Where they overlap
3ds max v7
3D Modelling Tools 7
Subtraction Subtraction (or difference)
The Boolean object contains the volume of one original object with the intersection volume subtracted from it

3D Modelling Tools 8
Activity Make a fruit bowl
3D Modelling Tools 9
Compound objects Loft Boolean Terrain Blobmesh
Metaballs Connect And more
3D Modelling Tools 10
Terrain Creates terrain
objects from contour line data
3ds max v7
3D Modelling Tools 11
BlobMesh The BlobMesh
compound object generates metaballs or spheres
For simulating thick liquids and soft substances that move and flow when animated

3D Modelling Tools 12
Connect Connect two or
more objects between "holes" in their surface
3ds max v7
3D Modelling Tools 13
Activity Connect two cylinders together
3D Modelling Tools 14
Using editable poly objects 1 Leave adding any texture maps until your
modelling is finished Meshes can have other meshes attached Meshes can be sliced or cut Smoothed
> Modifiers menu > Mesh Editing > Smooth or > Modifier menu > Object-Space Modifiers >
TurboSmooth Uses NURMS Non-Uniform Rational Mesh Smooth Adds edges Can be turned on whilst modelling in polys
3D Modelling Tools 15
Using editable poly objects 2 Tessellated
Increase the density of faces or edges Split or insert a vertex Caped Bridged Hinged from an edge Extruded Extruded along a spline
3D Modelling Tools 16
Painting Deformations Use a ‘brush’ to deform the surface
E.g. add veins to an arm Work with a terrain
3D Modelling Tools 17
Working with mesh modifiers MultiRes modifier Reduces the
number of polygons
Very useful for low polygon meshes for gaming
Attach your textures after

A problem How to model a mini How do I go about it?
3D Modelling Tools 19
Research – Pictures and sizes Length/width/height: 3.6 x 1.9 x 1.4
meters
MINI Cooper pictures and MINI Cooper videos
3D Modelling Tools 20
Research - How to model? How have other people modelled
something similar? What method has been used here?

More research – using pictures How do you find
out how to model from a pictures?
Remember to include this type of research into your documentation
3ds max v7
3D Modelling Tools 24
Activity Using the pictures of the mini in the
viewport create a block model
3D Modelling Tools 25
Mini Steps 1 Create a box to the right overall size
3.6 x 1.9 x 1.5 meters Set up a viewport background
Calibrate the background image Make the images have the same heights/widths of the
object and centred on the object Make sure that your calibration box is centred on the
origin Lock Zoom/Pan
locks the background image and objects together Create the body
Create a box, what size? Convert to a poly Extrude a number of times
3D Modelling Tools 26
Mini Steps 2 Shape the body using vertex, edges
and transform Mirror Connect or weld Smooth the mesh Perform MultRes Perform Boolean to make wheel
rims
3D Modelling Tools 27
To come Independent study
Work on Portfolio 4 Work on research and storyboard for
Model A Due Week 8
3D Modelling Tools 28
Portfolio 4 Make a model
of a claw with four fingers and a thumb
3D Modelling Tools 29
Questions You have been asked to model a
mini car for use in a game Describe the steps you would take in
planning the model List at least three sources you could
use to research how to build your model
Discuss and evaluate 3 different methods to model the car, make a recommendation for one
Describe how you would reduce the file size of the mesh
3D Modelling Tools 30
Impendent study Directed reading 3DS Max 7 Bible
Read Chapter 14, 15, 16 and 17 Portfolio 4 Presentations next week Tutorials
Modelling a Claw Modelling an Airplane Lofting a Telephone
