Introduction to Maya - James Tedder

TASK 1 1: Create a barrel: 2: Create a coliseum: Tutorials available at jamestedder.net TASK 2 1. Create a 3D wine glass using surfaces

2. Create a table and chairs with materials/textures UNDERSTANDING THEORY AND APPLICATION OF 3D Modelling techniques, constraints and 3D development software James Tedder BOX MODELLING A technique where a primitive shape (such as

a box, cylinder, sphere, etc.) is used to make the basic shape of the final model. This basic shape is then used to sculpt out the final model. EXTRUSION MODELLING Sometimes referred to as inflation modeling. The user creates a 2D shape which traces the outline of an object from a photograph or a drawing.

CONSTRAINTS: POLYGON COUNT The number of polygons you should use depends on the quality you require and the platform you are targeting. For mobile devices, somewhere between 300 and 1500 polygons per mesh will give good results Desktop platforms the ideal range is about 1500 to 4000. You may need to reduce the polygon count per mesh if the game has lots of characters on

screen at any given time. CONSTRAINTS: FILE SIZE Large models and textures can create huge file sizes. Increasing upload, download and loading times while also increasing the amount of storage the end user will need on their device.

Reducing the polygon count is one way to decrease file size. Having texture files that are appropriate for the target device is another. CONSTRAINTS: MAYA OPTIMIZATION To... Do this Remove empty, invalid, Select File > Optimize

and unused information Scene Size. from the scene. Remove construction history from the selected object(s). Only do this if you are sure you do not need to edit the objects history again. Select the objects and select Edit > Delete by

Type > History. CONSTRAINTS: RENDERING TIME Pre-rendered: The 3D image or animation is rendered over a period of time. This could be between a few seconds to several hours or, in extreme cases, days. It took 29 hours to render a

single frame of Monsters University At 24 frames per second and with a movie length of 1h44m there is 149,760 frames to render. CONSTRAINTS: RENDERING TIME Real time: Typically using a Graphics processing unit (GPU), with video games the most notable users. The 3D image is created

in real time on the fly 3D DEVELOPMENT SOFTWARE 3D development software: 3D Studio Max, Maya, Lightwave, AutoCAD, Cinema 4D, Blender, Mudbox; File formats: eg 3ds, .mb, .lwo, .C4d, .dxf, .obj; Plug-ins: Various add-ons can be applied to Maya. To open the Plug-in Manager, select Windows

> Settings/Preferences > Plug-in Manager from the main menu bar. THEORY AND APPLICATION OF 3D Session aim: Further understand modelling theory and implement techniques. All: Complete barrel and coliseum. Coliseum to include nurbs. Video tutorials available at jamestedder.net Most: Create a 3D wine glass using nurb

surfaces. Video tutorial available at jamestedder.net. Some: Additional model to also be created suggest: table and chairs.
