## Tranformations

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. All of our shape generators center the shapes around the origin. As we carve out new shapes using boolean operations, we want to be able to transform parts so that […]

## Button

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Here’s an unsung hero whose worth isn’t recognized until it’s gone: Just in case you lose one and need to print a replacement, you should have a 3D model of […]

## D6

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Future archaeologists will someday dig up our modern-day homes, and they will find many of these artifacts: This is a six-sided die, known as a D6 to gamers who must […]

## Bowl

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Every archaeological dig seems to turn up a bowl. Our species has been making them for millenia, so it only seems right to make one out of code. Write a […]

## Square Pot

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Consider the square pot below, which is just asking you to fill it with soil and plants. Or maybe pens and pencils. Or maybe ice and lemonade. Write a function […]

## Chain

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. With these next few exercises, you are given only an image of a target shape and function specification. It’s up to you to deduce what boolean operations are happening to […]

## Tube

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Earlier you made a cylinder. That was fun, but now you will do something tubular. You will make a tube, which is a thin cylinder taken away from a thick […]

## Boolean Utilities

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. Composing boolean meshes is a complex task that requires time and knowledge exceeding the bounds of this camp. Instead of implementing the boolean operations yourself, you will use a library […]

## Range-mapping

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. When you go to the doctor’s office, you may see a chart on the wall suggesting different ways of measuring the severity of your pain. Consider this chart, for example, […]

## Extrude

This post is part of a course on geometric modeling at the Summer Liberal Arts Institute for Computer Science held at Carleton College in 2021. You’ve now made two flat shapes. Suppose you took one of the shapes and stretched it into the third dimension to produce a solid rod or dowel. That stretching is […]
