Basic extrusion example: Shape -> ExtrudeGeometry -> Mesh
const { renderer, scene, camera } = initThree();
//Create a frame shape..
var frame = new THREE.Shape();
frame.moveTo(-4, -3);
frame.lineTo( 4, -3);
frame.lineTo( 4, 3);
frame.lineTo(-4, 3);
//..with a hole:
var hole = new THREE.Path();
hole.moveTo(-3, -2);
hole.lineTo( 3, -2);
hole.lineTo( 3, 2);
hole.lineTo(-3, 2);
frame.holes.push(hole);
//Extrude the shape into a geometry, and create a mesh from it:
var extrudeSettings = {
steps: 1,
depth: 1,
bevelEnabled: false,
};
var geom = new THREE.ExtrudeGeometry(frame, extrudeSettings);
var mesh = new THREE.Mesh(geom, new THREE.MeshPhongMaterial({ color: 0xffaaaa }));
scene.add(mesh);
renderer.render(scene, camera);
body {
margin: 0;
overflow: hidden;
}
canvas {
display: block;
}
