Let's breathe some life into our ball using a key animation principle: squash and stretch.
Now let's think about how subdivision would work in 3D.
Next we need to throw away the slope-intercept form and use the line equation instead.
Bonus! In this video we'll connect the degree of these curves to the number of control points in the construction.
Now we are ready to ray trace in 3D. We'll look at the problem of ray triangle intersection.
Finally, let's bring our parabolic arc to life!
Review of how to write a function (starting with translation)
Why do we divide the number of combinations by the number of permutations?
Try out your deformers on a face.
Finally we'll need to rotate object to finish our scene.
Now we just need to determine whether our intersection point is inside or outside the triangle.
Let's put everything together. Get ready for a really powerful formula: the binomial coefficient (warning: you may need to watch this a few times!).
Time to get a little mathy. Let's look at the general form for any transformation.
Review how to connect our deformers and shapes together

Questions about access to scholarship go back farther than recent debates over subscription prices, rights, and electronic archives suggest. The great libraries of the past—from the fabled collection at Alexandria to the early public libraries of nineteenth-century America—stood as arguments for increasing access. In The Access Principle, John Willinsky describes the latest chapter in this ongoing story—online open access publishing by scholarly journals—and makes a case for open access as a public good.
A commitment to scholarly work, writes Willinsky, carries with it a responsibility to circulate that work as widely as possible: this is the access principle. In the digital age, that responsibility includes exploring new publishing technologies and economic models to improve access to scholarly work. Wide circulation adds value to published work; it is a significant aspect of its claim to be knowledge. The right to know and the right to be known are inextricably mixed. Open access, argues Willinsky, can benefit both a researcher-author working at the best-equipped lab at a leading research university and a teacher struggling to find resources in an impoverished high school.
Willinsky describes different types of access—the New England Journal of Medicine, for example, grants open access to issues six months after initial publication, and First Monday forgoes a print edition and makes its contents immediately accessible at no cost. He discusses the contradictions of copyright law, the reading of research, and the economic viability of open access. He also considers broader themes of public access to knowledge, human rights issues, lessons from publishing history, and "epistemological vanities." The debate over open access, writes Willinsky, raises crucial questions about the place of scholarly work in a larger world—and about the future of knowledge.
This activity guides students through the evaluation of a website that they have created to see if it is accessible for users with disabilities. Students will simulate a number of different disabilities (e.g. visual impairments, color blindness, auditory impairments, motor impairments) to see if their website is accessible; they will also use automated W3 and WAVE tools to evaluate their sites. Students will consider the needs of users with disabilities by creating a persona and scenario of a user with disabilities interacting with their site. Finally, students will write up recommendations to change their site and implement the changes.
Comments
Although this activity can be used in isolation, it is intended to be part of a series guiding students towards the creation of a front-end of a website. The series (all published as OER) consist of:
a) Needfinding
b) Personas, Scenarios and Storyboards
c) Front-end Website Design and Development
d) Accessibility Evaluation
This presentation introduces Computer Science students to the notion of accessibility: developing software for people with disabilities. This lesson provides a discussion of why accessibility is important (including the legal, societal and ethical benefits) as well as an overview of different types of impairments (visual, auditory, motor, neurological/cognitive) and how developers can make their software accessible to users with those disabilities. This lesson includes videos and links to readings and tutorials for students.
