This is a simulation showing what it would be like if the universe were
a 3-sphere. It is the three-dimensional analogue to what a
two-dimensional person would see if their universe was the surface of a
sphere: for example, if you keep walking forward long enough, you'll
get back where you started.
It's intended to run in any browser that supports WebGL.
To run:
0. It is written in Idris2. As of 2022-01-17, you will need idris2
installed with this change:
https://github.com/idris-lang/Idris2/pull/2100
You'll also need to install the idris2-dom package and its transitive
dependencies idris2-experimental, idris2-elab-util and idris2-sop.
Each package is available at https://github.com/stefan-hoeck/$package_name
1. Build the precompute executable:
idris2 --build s3d_precompute.ipkg
2. Generate the S3D.Polyhedra.Precomputed module:
build/exec/s3d_precompute > src/S3D/Polyhedra/Precomputed.idr
3. Build by running
idris2 --cg javascript --build s3d.ipkg
4. Open Main.html in a web browser.
To run the tests:
idris2 --build s3d_test.ipkg
build/exec/s3d_test
The src directory is shared by all the *.ipkg files.
