3 This is a simulation showing what it would be like if the universe were
4 a 3-sphere. It is the three-dimensional analogue to what a
5 two-dimensional person would see if their universe was the surface of a

9 It's intended to run in any browser that supports WebGL.
11 To run:
13 0. It is written in Idris2. As of 2022-01-17, you will need idris2
14 installed with this change:
15 https://github.com/idris-lang/Idris2/pull/2100
17 You'll also need to install the idris2-dom package and its transitive
18 dependencies idris2-experimental, idris2-elab-util and idris2-sop.
19 Each package is available at https://github.com/stefan-hoeck/$package_name
21 1. Build the precompute executable:
22 idris2 --build s3d_precompute.ipkg
24 2. Generate the S3D.Polyhedra.Precomputed module:
25 build/exec/s3d_precompute > src/S3D/Polyhedra/Precomputed.idr
27 3. Build by running
28 idris2 --cg javascript --build s3d.ipkg
30 4. Open Main.html in a web browser.
32 To run the tests:
33 idris2 --build s3d_test.ipkg
34 build/exec/s3d_test
36 The src directory is shared by all the *.ipkg files.
