> 30° projection + Lambert shadow for [dominium](../README.md).
|
|
|
|
Pure math of isometric projection: `(x, y, z_world) → (sx, sy_screen)` at 30° angle with configurable scale. Lambert shadow proportional to dot product between normal and light. Zero graphics deps — this produces coordinates, [`dominium-render-plan`](../dominium-render-plan/README.md) uses them.
|
|
|
|
## API
|
|
|
|
```rust
|
|
use dominium_iso::{project, lambert};
|
|
|
|
let (sx, sy) = project(x, y, z, scale);
|
|
let shade = lambert(normal, light);
|
|
```
|
|
|
|
## Deps
|
|
|
|
- `libm`
|
|
- Zero external deps
