CGDD 4113 Final Review

Chapter 7: Maya Shading and Texturing

Maya topics covered in this chapter include the following:

• Shader Types
• Shader Attributes
• Texturing the Axe
• Life, Love, Textures and Surfaces
• UVs, oh, UVs!

2

Shader Types

• Shader Types are

loosely defined by how they reflect light and highlights (specular)

• Lambert
• Phong
• Phong E
• Blinn
• Anisotropic
• Layered Shader
• Ramp Shader

3

Shader Attributes

• Color
• Transparency
• Translucence
• Ambient Color
• Incandescence
• Bump Map
• Diffuse
• Glow
• Specular Color
• Reflectivity
• Reflected Color

4

Life, Love, Textures and Surfaces – Texturing the Red Wagon

• Creating shader

networks and file textures

• Understanding the

relationship between meshes and how their textures lay across them is important

• Use ramps to

position colors and textures

5

The magic of UVs

• UVs define the coordinate

space along a surface or mesh

• UVs must be laid out well for

textures to be applied properly

• Projection nodes can place

textures on objects with poor UVs

• The UV Editor allows you to

manipulate and export UVs to be painted or aligned in Photoshop

Chapter 8: Introduction to Animation

Maya topics covered in this chapter include the following:

• Keyframe animation

– Animating a ball

• Throwing an Axe

– Path Animation

• Object Replacement
• Setup for Animation
• Animating a Catapult

8

Keyframing

• Bouncing a ball is

the best introduction to animation concepts

• It’s usually best to

begin with overall animation and timing keyframes, then finesse

• Creating a hierarchy

to help isolate animation

• Editing Animation –

Graph Editor

• Reading and

Adjusting Animation Curves

9

Animating Along a Path

• Creating Text in

Maya

• Objects can

travel along a pre-defined path (a curve)

• Objects may

also deform along their animation path

Chapter 9: More Animation!

Maya topics covered in this chapter include the following:

• Skeletons
• Binding to Geometry
• IK
• Constraints
• Set Driven Keys
• Rigging
• But wait, there’s more!

12

Skeletons and Kinematics

• Skeletons

are a way to visualize pivots in a hierarchy

• FK and IK
• Walk Cycle

Mechanics

– Pose – Time – Refine – Check

13

Binding to Geometry

• Drawing the

Skeleton into place

• Moving joints

for proper placement in the model

• Smooth Bind
• Interactive

Bind

• Editing Binds

for better animation results

14

IK, ok?

• IK is a way to solve

the motion of a skeletal rig

• IK Handles are

positioned and animated which in turn pose and animate the skeleton

• IK Handles can keep

your feet on the ground!

• IK Walk cycle is a

little bit less traumatic than FK

• Character animation

gets easier with tons of practice and attention!

15

Constraints

• Constraints keep
• bjects in a

specific relation to each other and are very useful for rigging and setup

• Point
• Orient
• Scale
• Aim
• Geometry and

Normal

• Parent

16

Set Driven Keys

• SDKs maintain

controls of object attributes through another object’s actions

• You can create

complex movements of several parts of an

• bject by

assigning an SDK to run multiple joints or parts or even shader settings like color.

• What, did he say

color?

17

Rigging

• Automating

animation is a huge time saver

• Time spent in

rigging is time saved in animation

• Complex systems

can be animated based on the animation of a single object

• We create

relationships between the mechanics of the locomotive so that the rotation of a single wheel drives everything else

18

Simple Character Rig

• Controllers are animated,

not the IK handles or joints!

• Relationships and

constraints are setup to connect the controllers to the appropriate parts

• f the rig.
• Node Editor can be

handy to set exact relationships.

• Setting up a heel control.

Chapter 10: Maya Lighting

Maya topics covered in this chapter include the following:

• Basic Lighting Concepts
• Maya Lights
• Light Linking
• The advancement of smoothie

technology in the past decade

• Shadows
• mental ray Lighting
• mental ray Physical Sun and Sky
• Special Lighting Effects

21

Lighting Concepts

• You have to

learn how to see all over again

• Proper

Exposure

• Three-Point

Lighting Basics

– Key Light – Fill Light – Rim Light

• Practical Lights

22

Maya Lights

• Light Attributes

– Intensity – Emit Specular/Diffus e – Decay Rate

• Types of Lights

– Ambient – Directional – Point – Spot – Area – Volume

23

Light Linking

• Linking

Lights allow you to light some

• bjects in

the scene but not

• thers
• Gives you

greater control in your scene

24

Only the Shadow Knows

• Creating Shadows

– Depth Map serve most purposes and are relatively fast to render – Raytraced Shadows are more accurate but more costly to render – Soft shadows may be had using mental ray or raytracing

25

Light Effects

• Volumetric effects

such as fog add atmosphere to your lights

• Lens Flare can

heighten realism

• Shader Glow

mimic glowing

• bjects, but are

Shader based and not light based
