By double-clicking the selection tool
What is soft selection?
Selection by the distance from the fully selected element
Fall off radius: Surface
Nearest path along the surface
Fall off radius: Object
Move objects/select them depending on the distance from the origin object
How do you keep drop menus open when selecting?
By holding down the control key
What does Shift M do?
Shows and hides the menu in the viewport
What does control M do?
Shows and hide the menu in the main interface
What is the shortcut key for the last command?
How do you access the creation menu?
Shift Right Click
Should be even around the axis
How do you get more control when adjusting objects?
Control-Drag in the input box
True or False: Layers can't have the same name as the object.
Layers: What does the P Key do?
Shows/Hides on playback
Layers: What does the T Key do?
Layers: What does the R Key do?
Object becomes non selectable from the viewpoint
How do you isolate an object.
Select the object and hit control-1
Characters communicate non-verbally in 3 different ways:
- Expression - Movements of the muscles in the face
- Gesture - Arms, hands, fingers
- Posture - Emotion
How an audience understands a character’s role in a story
Proportions: Young Child Head Height to Body Height
Proportions: Adulthood Head Height to Body Height
1:7 or 1:8
What is the only part of the body that grows throughout life
- Easily communicated through eyebrows: Distance and Shape
- Minimize the distance between eye and eyebrow
- Expressive Eyelids
- Use cultural shortcuts
- Style of Character
Size and Shape
Makes characters easily recognizable
- Make characters to have gestures and expressions
What are the fundamental building blocks of polygon models?
- Never use spaces or hyphens
- Use Camel Case and underscores
What does NURBS stand for?
Non Uniform Ration B-Splines
Sections of curves can be independently edited
Control Vertices can be given different weights
A basis spline defined by CVs making up a hull
Where are Isoparms lined up?
Across the surface
Do NURBS Patches use U and V directions or X, Y, and Z directions?
U and V directions
What do NURBS Patches share characteristics with?
Difference between NURBS and Subdivision surfaces
Subdivisions are one seamless surface
NURBS models are often made up of many patches
Which cannot have surface curvatures precisely defined: NURBS or Subdivision surfaces?
NURBS and Subdiv
Which are iterative and which are precise?
Subdivisions are an iterative process
NURBS are precise
Poly Modeling and NURBS:
Which is best for animation and 3D printing
Poly Modeling and NURBS:
Which is best for manufacturing and surface analysis?
Who at Pixar developed subdivision surfaces?
Why were subdivision surfaces developed?
Because the NURBS used for animation in early days would result in cracks between the surfaces
What do more CVs allow for but lack as a result?
More detail but lack control needed for design work
NURBS Patches are __ sided
What do NURBS always have?
What does the Make Live tool do?
Allows for drawing a UV Curve in the UV space of the patch
- Boatbuilding Term
- Have cross sections
- Build surfaces by selecting the cross sections in the appropriate order
The art and technology of creating 3D characters that can be distorted realistically without producing shading artifacts.
Vertices with less than 4 edges flowing into them break the edge loops
5 or 6 pointed vertex
A way to multiply the numbers of faces in a line.
What is Arnold?
Maya’s inbuilt rendering engine
Does Arnold support Toon Shading?
What rendering engine should you use for Toon Shading
Create toon shading based on the light angle
Separate from the fill and controllable independent from the fill shader
The color of something under diffuse light (eg. Cloudy day)
What latin word does the term "camera" come from?
“Chamber” or “room”
- Lightproof tents with small hole in one wall
- The smaller the hole, the shaper the image
- The Larger the hole the fuzziness of the image because of more light
What are camera lenses used for?
To provide more light without making the pinhole larger
What do lenses create?
Unwanted Focal Length which affects the way imaged are rendered
- Fixed focal length
- Advantage is you don’t have all the adjustment mechanism, have a larger aperture
What is an ideal Focal Length?
Between 50mm and 70mm
What happens with a focal length of 100 or more?
The image becomes flat
What is the focal length of orthographic cameras
Allows the user to adjust the amount of light entering the camera
Depth of field
- The range of distances from the image plane that are in sharp focus.
- The distance between the nearest and furthest objects in a scene that appear sharp.
- Miniaturizes elements of the photograph.
Known for taking landscape photographs with a pinhole sized aperture
Three Point Lighting
Uses a Key or Main light for the main planes of the subject
Removes any dark areas
Back or Rim Light
- Pops the subject out of the background
- Important with black and white films
- Color adds information to shape and form
- The shorter wavelength the more energetic and damaging they are
- Infrared – Heat
All colors add up to white
- Monitors, stage lights, projectors, and light emitting objects
- Transparency (Alpha Channel)
- PNG or TARGA files
- Z Channel – Depth of each element of the picture from the camera
All colors add up to black
- Printing inks, paint work
- Absorb specific wavelengths of light
Splitting sunlight almost white light
What influences color in an image
- The color of the original material
- Color or lighting of the surroundings
- The Level of lighting
- Eyes are sensitive to blue
- Movies shot under blue light at night
- The atmosphere (fog, absorption)
- Objects appear blue from far away
- Reds are absorbed by the atmosphere
- Additive or subtractive media (print, monitor)
- The accuracy of the inks or monitor setup
- The observer’s vision
The range of colors that can be shown by a medium
- CMYK is smallest
- Standard RGB is better but is digital
- Film – Widest color gamut
The number of distinct colors an image can contain
Color Depth: 1 bit
Black and White
Color Depth: 8 bit
Indexed Color - 256 colors
Color Depth: 24 Bit
Full Color - 16.7 Million colors
3 Color Channels
- Each channel is a greyscale image
- Indicates how much of that particular color the pixel contains
Function of the limited amount of information that is available to describe the grey.
