Business and Computing Deanery 3D Modelling Tools 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 a - b b - a 3ds max v7

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 3ds max v7

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

3D Modelling Tools 18 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? Omernick, M., (2004)

3D Modelling Tools 21 Research - How to model? What method has been used here? Omernick, M., (2004)

3D Modelling Tools 22 Extrusion Omernick, M., (2004)

3D Modelling Tools 23 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 Lecture week after Intro to Materials
