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
objects 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 object 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 of 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/Diffuse
– Decay Rate• Types of Lights
– Ambient– Directional– Point– Spot– Area– Volume
23
Light Linking• Linking
Lights allow you to light some objects in the scene but not others
• 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 objects, but are Shader based and not light based
