E-notes features 3D models, simulations, and illustrations of everything from protein molecules to flower bouquets. Whether you want to browse the many visualizations of complex equations or get an introduction to WebXR, this site is a comprehensive resource for anyone interested in math, science, or computer graphics!
Below is a preview of a few of the topics explored throughout E-notes. To learn more about science and technology, head to the Technology and Applied Sciences section of ibiblio’s catalog. You can also check out this post for 3D modeling tutorials.
This section contains models of animals and objects made using WebGL. There are even animated models with adjustable cycles, like this eagle. Since these models are interactive, you can wheel the models and zoom in using your mouse or trackpad to view the graphics from different angles. There are also WebXR samples where you can edit the appearance directly in your browser, like this flower.
These interactive models show the atomic structure of crystals like diamonds and salt. You can explore the models in multiple cell sizes and learn about the types of patterns that crystal atoms create, which are called Bravais lattices. This page also links more resources for learning about crystallography.
Fractals are geometric shapes that repeat parts of themselves in different sizes and scales. Irregular fractals occur in nature, but it is also possible to create fractal images using math (BBC). The Mandelbrot and Julia sets, illustrated on this page, are some of the most recognizable fractals in mathematics. Like the 3D graphics mentioned above, you can zoom in on the images to get a closer look at the symmetry and complexity of these structures.
