How can I generate cone shape with rectangular base using three.js?

Interested in building a Cone Geometry with a rectangular base in three.js. Any tips on how to get started?

I've included an image to help visualize what I'm trying to achieve.

Answer №1

A cone with a square base can be thought of as a special case of a cylinder with four sides and one of the base radius set to 0.

If you want to create a generic cylinder, you can use the following code snippet:

THREE.CylinderGeometry(radiusTop, radiusBottom, height, radiusSegments, heightSegments, openEnded)

For instance, you could create the following specific example:

THREE.CylinderGeometry(0, 30, 80, 4, 1, true);
