Shorter than 3 minutes
-
Where in the demo reel should your best work be?
The start start and end
-
Where to post demo reel
- Vimeo
- You Tube
- Your Site – host elsewhere
-
What should come with your demo reel?
A breakdown sheet
-
What format should you resume be in?
PDF
-
Serial Position Effects
Things presented at the beginning and end of a sequence are more memorable than things presented in the middle
-
UV mapping
The art of distorting and applying a square image and wrapping it around the 3D object
-
2D UV mapped image has to be ________ to fit on a 3d surface
Distorted
-
Why are UV maps all square?
To minimize image format efficiency
-
Textures
- Images in resolution that are multiples of 2n.
- Use same UV map as other textures or custom UV map
-
Diffuse (color map)
Affects the color of the rendered object
-
Specular
Affects the shininess
-
Glow
Makes parts of the object appear to emit light
-
Normal
Appears to add finer detail than exists
-
Bump/displacement
Moves actual geometry to add detail. Use greyscale maps
-
Procedural
Applies a non-repeating mathematical transformation to the surface of the object
-
Rendering
Rendering is the process of making an image from 2D or 3D model (or scene) by means of computational processes.
Contains objects in a defined data structure including geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene.
-
Rendering Specifications
- Resolution
- Aspect Ratio
- Format
- Color Depth
- Channels
-
Image Sequences
When rendering an animation save the frames as separate images with an alpha channel, not video format.
- Alpha channel for editing
- Preserve maximum edibility
- Preserve maximum image quality
- Backup images in case of computer crash during rendering
-
Image Compression
Image formats use image compression to reduce the size of the resulting file.
-
What does the file size in image compression depend on?
- Format
- Content
- Resolution – number of pixels compressed
- Color Depth – number of bits per pixel per channel
- Aspect Ratio – square images compress slightly better
- Number of Channels
-
Lossy compression
- Throws away data that will not be perceived by the user.
- Info cannot be recovered
- Results in very small files that look or sound the same as the original
-
Lossless compression
Not effective in reducing size but allows all the original data to be recovered
-
Spatial Compression
Each frame is individually compressed
-
Temporal Compression
Sequences of frames are compared and similar areas over that time are reduced to a common element
-
Shaders
Calculate material appearance from the angle of faces to the camera, lighting, color, and specularity.
-
Lambert
Calculates brightness due to diffuse reflection
-
Phong
Calculates ambient, diffuse, and specular lighting
-
Anisotropic
Simulates brushed metal surfaces
-
Bitrate
- The amount of data or bits that are being used every second
- If a video has a low bitrate, it will be low resolution with lots of compression artifacts
- If a video has a high bitrate if will be high quality/high resolution
-
Rigging
Creating a series of bones inside a model
-
Rigging process
Defining relationships between the bones
-
4 IKinematics
- Hierarchy travels along the limbs to the end
- In order to move the tips of the fingers you have to move the upper and lower arms, the hand, base of the finger, middle of the finger, and the tip of the finger
- IK reduces the flow of control along the hierarchy
