Simulate reflection and refraction of light.
- Simulate various light sources: ray, beam, and point source
- Simulate reflection in linear, circular, and parabolic mirror
- Simulate beam splitter
- Simulate refraction in linear or circular interfaces, including both refracted and reflected rays
- Simulate ideal lens/mirror, which obeys lens/mirror equation
- View extensions of rays to see if they converge to a virtual image
- View real images, virtual images, and virtual objects directly
- View images that can be observed from some given position
- Distance, angular, energy flow, and momentum flow measurements
- Export as SVG diagram
If you created a good sample, please submit a pull request to let others see your work!
Clone the repo: git clone https://github.com/ricktu288/ray-optics.git
Open simulator/index.html locally in you browser (or start an http server in the repo directory if "Sample" does not work).
The structure of a tool is described in the template here. To view the code of an existing tool, you can search for objTypes['id_of_the_tool'] = in index.js.
| Name on the toolbar | ID of the tool |
|---|---|
| Ray | laser |
| Beam | parallel |
| Point source | radiant |
| Mirrors -> Segment | mirror |
| Mirrors -> Circular Arc | arcmirror |
| Mirrors -> Ideal Curved | idealmirror |
| Mirrors -> Parabolic | parabolicmirror |
| Mirrors -> Beam Splitter | beamsplitter |
| Glasses -> Half-plane | halfplane |
| Glasses -> Circle | circlelens |
| Glasses -> Free-shape | refractor |
| Glasses -> Ideal Lens | lens |
| Glasses -> Spherical Lens | sphericallens |
| Blocker | blackline |
| Ruler | ruler |
| Protractor | protractor |
| Detector | power |
| Text | text |
I'm sorry that most of the comments in index.js are in Chinese. For now, you can see the template for some explanations in English.
After you complete the code objTypes['id_of_your_tool'] = {...};, a quick way to test it without modifying the toolbar is to execute the code directly in your browser's developer tool. And when you want to choose the tool, execute AddingObjType = 'id_of_your_tool'.
You can just search for an existing tool id such as protractor or beamsplitter in simulator/ToolBarViewModel.js, simulator/index.html, simulator/index.js, and simulator/locales/en.js and add the corresponding lines for your tools. And also include an exported SVG image (use the "export" button) of your tools in img/id_of_your_tool.svg cropped to a suitable size.
If you create a useful tool, please submit a pull request to let others use your tool! (We will add the Chinese locales for it.)
