# Orthogonality
## MicroSim spec
- **Recommended sim type:** basis / independence
- **Microsimmability score:** 76/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Cross-coupling`
- `Dimensions`
- `Change magnitude`
### What animates
Adjusting one axis leaves others fixed when orthogonal, but smears them as cross-[[Coupling|coupling]] rises, shown on a basis grid.
### Learning objective
Relate side-effect-free change to dimensional independence.

## Concept summary
Orthogonality is the property that changing one feature or dimension has no side effects on others, like independent axes.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to system quality attributes)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Orthogonality
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render basis / independence; respond live.
}
```
