This video introduces the transformations we'll be using in the rest of this lesson.
How do we keep track of how many robots we've made?
Before building characters you need to define individual shapes using objects.
Now we attach our particle to a spring.
First let's think about how to rotate some really simple points such as (0,0) and (1,0)
First we'll use the slope intercept form of a line to define each frame along a straight line.
First let's look at ray tracing in 2D using a simple example.
First you'll connect shapes together using joints that rotate.
First we need to make sure we understand exactly what happens in the split & average steps.
Let's start by drawing every frame, one by one...
Find out how we can make curved lines using straight ones using the string art construction.
What happens if the director changes their mind and asks for two headed robots?
First we'll review weighted averages of two points and extend the idea to three points. Practice weighted averages of two points in Environment Modeling if you haven't seen it before.
How can we calculate a weighted average between two points? (pssst. This video is super important).
Introduction to the basics of ray tracing.
In this activity, students determine their own eyesight and calculate what a good average eyesight value for the class would be. Students learn about technologies to enhance eyesight and how engineers play an important role in the development of these technologies.
This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.
This NOAA visualization on YouTube shows the seasonal variations in sea surface temperatures and ice cover from 1985 to 2007. The visualization is based on data collected by NOAA polar-orbiting satellites. El Niño and La niña are easily identified, as are the trends in decreasing polar sea ice.
Now we add a horizontal component to our system.
Next lets build a diagram that break rotation into smaller parts. The next exercise will give us a chance to build our understanding of this diagram.
