## Prototype
|
||||
|
||||
The latest prototype is in the folder `app-proto`. It includes both a user interface and a numerical constraint-solving engine.
|
||||
|
||||
### Install the prerequisites
|
||||
|
||||
1. Install [`rustup`](https://rust-lang.github.io/rustup/): the officially recommended Rust toolchain manager
|
||||
- It's available on Ubuntu as a [Snap](https://snapcraft.io/rustup)
|
||||
2. Call `rustup default stable` to "download the latest stable release of Rust and set it as your default toolchain"
|
||||
- If you forget, the `rustup` [help system](https://github.com/rust-lang/rustup/blob/d9b3601c3feb2e88cf3f8ca4f7ab4fdad71441fd/src/errors.rs#L109-L112) will remind you
|
||||
3. Call `rustup target add wasm32-unknown-unknown` to add the [most generic 32-bit WebAssembly target](https://doc.rust-lang.org/nightly/rustc/platform-support/wasm32-unknown-unknown.html)
|
||||
4. Call `cargo install wasm-pack` to install the [WebAssembly toolchain](https://rustwasm.github.io/docs/wasm-pack/)
|
||||
5. Call `cargo install trunk` to install the [Trunk](https://trunkrs.dev/) web-build tool
|
||||
6. Add the `.cargo/bin` folder in your home directory to your executable search path
|
||||
- This lets you call Trunk, and other tools installed by Cargo, without specifying their paths
|
||||
- On POSIX systems, the search path is stored in the `PATH` environment variable
|
||||
|
||||
### Play with the prototype
|
||||
|
||||
1. From the `app-proto` folder, call `trunk serve --release` to build and serve the prototype
|
||||
- The crates the prototype depends on will be downloaded and served automatically
|
||||
- For a faster build, at the expense of a much slower prototype, you can call `trunk serve` without the `--release` flag
|
||||
- If you want to stay in the top-level folder, you can call `trunk serve --config app-proto [--release]` from there instead.
|
||||
3. In a web browser, visit one of the URLs listed under the message `INFO 📡 server listening at:`
|
||||
- Touching any file in the `app-proto` folder will make Trunk rebuild and live-reload the prototype
|
||||
4. Press *ctrl+C* in the shell where Trunk is running to stop serving the prototype
|
||||
|
||||
### Run the engine on some example problems
|
||||
|
||||
1. Use `sh` to run the script `tools/run-examples.sh`
|
||||
- The script is location-independent, so you can do this from anywhere in the dyna3 repository
|
||||
- The call from the top level of the repository is:
|
||||
|
||||
```bash
|
||||
sh tools/run-examples.sh
|
||||
```
|
||||
- For each example problem, the engine will print the value of the loss function at each optimization step
|
||||
- The first example that prints is the same as the Irisawa hexlet example from the Julia version of the engine prototype. If you go into `engine-proto/gram-test`, launch Julia, and then
|
||||
|
||||
```julia
|
||||
include("irisawa-hexlet.jl")
|
||||
for (step, scaled_loss) in enumerate(history_alt.scaled_loss)
|
||||
println(rpad(step-1, 4), " | ", scaled_loss)
|
||||
end
|
||||
```
|
||||
|
||||
you should see that it prints basically the same loss history until the last few steps, when the lower default precision of the Rust engine really starts to show
|
||||
|
||||
### Run the automated tests
|
||||
|
||||
1. Go into the `app-proto` folder
|
||||
2. Call `cargo test`
|
||||
|
||||
### Deploy the prototype
|
||||
|
||||
1. From the `app-proto` folder, call `trunk build --release`
|
||||
- Building in [release mode](https://doc.rust-lang.org/cargo/reference/profiles.html#release) produces an executable which is smaller and often much faster, but harder to debug and more time-consuming to build
|
||||
- If you want to stay in the top-level folder, you can call `trunk build --config app-proto --release` from there instead
|
||||
2. Use `sh` to run the packaging script `tools/package-for-deployment.sh`.
|
||||
- The script is location-independent, so you can do this from anywhere in the dyna3 repository
|
||||
- The call from the top level of the repository is:
|
||||
```bash
|
||||
sh tools/package-for-deployment.sh
|
||||
```
|
||||
- This will overwrite or replace the files in `deploy/dyna3`
|
||||
3. Put the contents of `deploy/dyna3` in the folder on your server that the prototype will be served from.
|
||||
- To simplify uploading, you might want to combine these files into an archive called `deploy/dyna3.zip`. Git has been set to ignore this path

In this vein, it seems as though if J1 and J2 are the reps of two points, then Q(J1,J2) = d^2/2. So then the sphere centered at J1 through J2 is (J1-(2Q(J1,J2),0,0,0,0))/sqrt(2Q(J1,J2)). Ugh has a sqrt in it. Similarly for sphere centered at J3 through J2, (J3-(2Q(J3,J2),0000))/sqrt(2Q(J3,J2)). J1,J2,J3 are collinear if these spheres are tangent, i.e. if those vectors have Q-inner-product 1, which is to say Q(J1,J3) - Q(J1,J2) - Q(J3,J2) = 2sqrt(Q(J1,J2)Q(J2,J3)). But maybe that's not the simplest way of putting it. After all, we can just say that the cross-product of the two differences is 0; that has no square roots in it.

One conceivable way to canonicalize lines is to use the *perpendicular* plane that goes through the origin, that's uniquely defined, and anyway just amounts to I = (0,0,d) where d is the ordinary direction vector of the line; and a point J in that plane that the line goes through, which just amounts to J=(r^2,1,E) with Q(I,J) = 0, i.e. E\dot d = 0. It's also the point on the line closest to the origin. The reason that we don't usually use that point as the companion to the direction vector is that the resulting set of six coordinates is not homogeneous. But here that's not an issue, since we have our standard point coordinates and plane coordinates; and for a plane through the origin, only two of the direction coordinates are really free, and then we have the one dot-product relation, so only two of the point coordinates are really free, giving us the correct dimensionality of 4 for the set of lines. So in some sense this says that we could take naively as coordinates for a line the projection of the unit direction vector to the xy plane and the projection of the line's closest point to the origin to the xy plane. That doesn't seem to have any weird gimbal locks or discontinuities or anything. And with these coordinates, you can test if the point E=x,y,z is on the line (dx,dy,cx,cy) by extending (dx,dy) to d via dz = sqrt(1-dx^2 - dy^2), extending (cx,cy) to c by determining cz via d\dot c = 0, and then checking if d\cross(E-c) = 0. And you can see if two lines are parallel just by checking if they have the same direction vector, and if not, you can see if they are coplanar by projecting both of their closest points perpendicularly onto the line in the direction of the cross product of their directions, and if the projections match they are coplanar.

#### Engine Conventions
|
||||
|
||||
The coordinate conventions used in the engine are different from the ones used in these notes. Marking the engine vectors and coordinates with $'$, we have
|
||||
$$I' = (x', y', z', b', c'),$$
|
||||
where
|
||||
$$
|
||||
\begin{align*}
|
||||
x' & = x & b' & = b/2 \\
|
||||
y' & = y & c' & = c/2. \\
|
||||
z' & = z
|
||||
\end{align*}
|
||||
$$
|
||||
The engine uses the quadratic form $Q' = -Q$, which is expressed in engine coordinates as
|
||||
$$Q'(I'_1, I'_2) = x'_1 x'_2 + y'_1 y'_2 + z'_1 z'_2 - 2(b'_1c'_2 + c'_1 b'_2).$$
|
||||
In the `engine` module, the matrix of $Q'$ is encoded in the lazy static variable `Q`.
|
||||
|
||||
In the engine's coordinate conventions, a sphere with radius $r > 0$ centered on $P = (P_x, P_y, P_z)$ is represented by the vector
|
||||
$$I'_s = \left(\frac{P_x}{r}, \frac{P_y}{r}, \frac{P_z}{r}, \frac1{2r}, \frac{\|P\|^2 - r^2}{2r}\right),$$
|
||||
which has the normalization $Q'(I'_s, I'_s) = 1$. The point $P$ is represented by the vector
|
||||
$$I'_P = \left(P_x, P_y, P_z, \frac{1}{2}, \frac{\|P\|^2}{2}\right).$$
|
||||
In the `engine` module, these formulas are encoded in the `sphere` and `point` functions.
