|
How many trianges the graphics card can calculate in one second. This is also the way we measure for the graphics card.
|
Poly Count
|
|
|
How many pixels the graphics card can color on screen in one second
|
Fill Rate
|
|
|
Simulates light coming from all directions by giving every polygon a minimum color.
|
Ambient Light
|
|
|
Simulates light coming from the sun; every polygon is lit from the same direction.
|
Directional Light
|
|
|
Doing a task with little wasted effort
|
Efficiency
|
|
|
A mathematical line that shows the direction of a polygon
|
Normal
|
|
|
An image placed on a polygon where each pixel doe not represent RGB. Instead those values are IJK which represents a normal direction.
|
Normal Map
|
|
|
Simulates light coming from a point in space; polygons are lit based on where they are relative to the light source.
|
Positional Light
|
|
|
A process where a four-sided polygon is divided into four smallery polys. These polys refine the shape based on other polys around them.
|
Subdivision Surface
|
|
|
Two common tools for efficiency
|
Hotkeys
Interface Buttons |
|
|
In order to accurately represent a 3D model, you must have what?
|
shading and light color information
|
|
|
To render 3D objects, we need two pieces of information.
|
Lighting direction
Surface direction |
|
|
How many kinds of "real light" are there?
|
One - Photon
|
|
|
How many types of lights are there in 3D Max? What are they?
|
3 - Ambient, Directional, Positional
|
|
|
Who first modeled the teapot and in what year?
|
Martin Newell 1975
|
|
|
The color generated by light on a polygon is what?
|
Shading
|
|
|
Three types of shading.
|
Lambert
Gouraud Per-Pixel |
|
|
What do we use to represent curves?
|
Triangles
|
|
|
What is the difference between Bump Maps and Normal Maps?
|
Bump- B&W
Normal - full color |
|
|
There are only two kinds of geometry. What are they?
|
Straight and Curved
|
|
|
what are the 4 layers in a model?
|
x,y,z
normals colors uvw |
|
|
what are the 4 most common tools used for efficient work flow?
|
hotkeys
popup menus interface buttons drop-down menus |
|
|
What is the difference between software and hardware rendering?
|
Hardware - very fast
Software - can do any graphical effect. Hardware - can only do certain effects. Software - Very slow |
