# orient-stl: MATH4630 Nonlinear Optimization Final Project
See [proposal.pdf](proposal.pdf) and [report.pdf](report.pdf) for more details on implementation and theory.
## Calculations in Mathematica
To verify the correctness of my objective function, I also mostly implemented it in Mathematica. See [calculations.pdf](calculations.pdf).
## Running
### Orient an STL file
```bash
python main.py examples/cube.stl orient
```
### Plot the objective function value for an STL file
```bash
python main.py examples/cube.stl plot
```
## Demo with cut cylinder.stl
### Original part orientation
### Corrected part orientation
```bash
> python main.py examples/cut cylinder.stl orientplot
`File "examples/cut cylinder.stl" oriented with angles [-2.62 -0. ] and value 0.12231975793838501 in 586 ms`
```
### Function value plot
```bash
> python main.py examples/cut cylinder.stl plot
Plotting function value for examples/cut cylinder.stl
Minimum value of 1.2497923374176025 found
```
