Calculus in Virtual Reality

Lessons about Calculus and Geometry in Virtual Reality!

We have added literal depth to calculus!
The CalcVR app uses a Google Cardboard headset to enable the user to visualize concepts in multi-variable calculus within a virtual reality setting. The user can specify their own objects for visualization as well go through lessons on the geometry and calculus of multi-variable functions and the corresponding surfaces. In addition to this, there are interactive demonstrations where the user can further explore the concepts covered in the lessons. Because these elements are rendered in a virtual the user can see the depth of these mathematical objects and the multiple facets at play in the study of these mathematics topics.
Users can use any Google Cardboard (v1.0, v2.0) or compliant viewer to work on lessons related to calculus and geometry in three dimensions. The headset should have a capacitive touch button or the user should use a Bluetooth controller

-The purpose of these materials is to introduce students to important ideas from multi-variable calculus in a virtual reality setting.
- These are not to be taken as a stand-alone set of materials, but instead are supposed to supplement student work and reading.
- We have designed these to work with either a single button interface or using a Bluetooth controller. We hope to add further functionality later, including sharks with laser beams on their head (not kidding about this, but sharks with lasers is harder than you think to implement...).
- It is very important to us that these materials are available and usable for the largest group possible. We have targeted the lowest required hardware restrictions possible. In the future we may develop more for the advanced VR sets, but Google Cardboard allows us to equitably engage the widest possible audience.
