Module meshmod 

Mesh modifiers: a Blender-style stack that reshapes an object’s mesh without touching the source model. Add MeshModifiers to an object with a Shape or a model and stack modifiers (Array, Mirror, Subdivide, Displace, Twist, Bend, Taper, Solidify) in any order.

The result is a DynamicMesh, rebuilt only when the stack or the source changes.

use kvas_engine::{prelude::*, scene::Scene, meshmod::*};
let mut scene = Scene::default();
let e = scene.spawn("Fence");
scene.world.insert(e, Shape::of(ShapeType::Cube));
scene.world.insert(e, MeshRenderer::default());
scene.world.insert(e, MeshModifiers(vec![Modifier::array(3, Vec3::new(1.5, 0.0, 0.0))]));
update(&mut scene.world);
assert_eq!(scene.world.get::<DynamicMesh>(e).unwrap().data.vertices.len(), 3 * 24);

Structs

MeshModifiers

The modifier stack of an object, applied top to bottom.

ModifierState

Cache of what the last build used, so unchanged stacks cost nothing.

ModifierStateCell

Runtime-only marker holding the build signature (never saved).

Enums

ModAxis

Axis a modifier works along.

Modifier

One entry of the stack. Fields are public so scripts can build stacks in code.

Functions

assets

The asset source set with set_assets, if any.

build

Runs the stack on a source mesh.

set_assets

Tells the modifier system where to load model files from (the editor and player call this).

update

Rebuilds the DynamicMesh of every object with modifiers whose stack or source changed.
