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?


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 Booleans Powerful sculpting tools Multiple objects Usually destructive

3ds max v7


Union Boolean Union or addition

The intersecting or overlapping portion of the geometry is removed.

3ds max v7


Intersection Boolean Intersection

Where they overlap

3ds max v7


Subtraction Subtraction (or difference)

The Boolean object contains the volume of one original object with the intersection volume subtracted from it

a - b b - a3ds max v7


Activity Make a fruit bowl


Compound objects Loft Boolean Terrain Blobmesh

Metaballs Connect And more


Terrain Creates terrain

objects from contour line data

3ds max v7


BlobMesh The BlobMesh

compound object generates metaballs or spheres

For simulating thick liquids and soft substances that move and flow when animated

3ds max v7


Connect Connect two or

more objects between "holes" in their surface

3ds max v7


Activity Connect two cylinders together


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


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


Painting Deformations Use a ‘brush’ to deform the surface

E.g. add veins to an arm Work with a terrain


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?


Research – Pictures and sizes Length/width/height: 3.6 x 1.9 x 1.4

meters

MINI Cooper pictures and MINI Cooper videos


Research - How to model? How have other people modelled

something similar? What method has been used here?

Omernick, M., (2004)


Research - How to model? What method has been used here?



Extrusion



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


Activity Using the pictures of the mini in the

viewport create a block model


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


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


To come Independent study

Work on Portfolio 4 Work on research and storyboard for

Model A Due Week 8


Portfolio 4 Make a model

of a claw with four fingers and a thumb


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


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

Lecture week after Intro to Materials
