|
||
|
||
Repeat a 3-dimensional solid by successively applying a transformation (such
|
||
|
||
as rotation, scale, translation, visibility) on each repetition.
|
||
|
||
```js
|
||
patternTransform(num_repetitions: u32, transform_function: FunctionParam, extrude_group_set: ExtrudeGroupSet) -> [ExtrudeGroup]
|
||
```
|
||
|
||
### Examples
|
||
|
||
```js
|
||
// Parameters
|
||
const r = 50 // base radius
|
||
const h = 10 // layer height
|
||
const t = 0.005 // taper factor [0-1)
|
||
// Defines how to modify each layer of the vase.
|
||
// Each replica is shifted up the Z axis, and has a smoothly-varying radius
|
||
fn transform = (replicaId) => {
|
||
let scale = r * abs(1 - (t * replicaId)) * (5 + cos(replicaId / 8))
|
||
return {
|
||
translate: [0, 0, replicaId * 10],
|
||
scale: [scale, scale, 0]
|
||
}
|
||
}
|
||
// Each layer is just a pretty thin cylinder.
|
||
fn layer = () => {
|
||
return startSketchOn("XY")
|
||
// or some other plane idk
|
||
|> circle([0, 0], 1, %, $tag1)
|
||
|> extrude(h, %)
|
||
}
|
||
// The vase is 100 layers tall.
|
||
// The 100 layers are replica of each other, with a slight transformation applied to each.
|
||
let vase = layer()
|
||
|> patternTransform(100, transform, %)
|
||
```
|
||
|
||
|
||
|
||
