slide7

Traditional Graphics

Conceptual world

Modeling

Simulation

Pros:

+ Compact representation

+ Easy to manipulate

Cons:

- Very hard to build realistic models

- Too complex to simulate

slide9

Data-driven Graphics

Data capture

Real world

Data analysis and synthesis

Pros:

+ High realism

+ Computer cost independent on the complexity of the model

Cons:

- Large set of data

- Hard to control, edit, modify

slide10

What You Will Learn
