code as follow:

const geometry = new THREE.CircleBufferGeometry(10, 64);

geometry.vertices.shift();

but receive an error that geometry.vertices is undefined when running，so how can I fix it?

Hi!

If you want points in formation of circle, then use this one-liner:

`let pts = new THREE.Path().absarc(0, 0, 10, 0, Math.PI * 2).getPoints(64);`

;

Example: https://jsfiddle.net/prisoner849/4z36cwgh/

Since r125, all standard/primitive geometries are buffer geometries, so there is no `.vertices`

property, as they store vertex data in `.attribute.position`

buffer attribute.
