What is the best way to make the Three.js camera focus on the front side of an object?

I have a unique sphere composed of hexagons and pentagons, and my goal is to align the camera directly with a specific hexagon so that it appears flat in the center of the user's view.

The hexagons are created using the hexasphere.js plugin (https://github.com/arscan/hexasphere.js/tree/master). While I can extract information from the mesh object representing a hexagon, I am unsure how to instruct the camera to focus on it.

My attempts involved utilizing the normal matrix element of the mesh and determining the euler angles, but I am stuck on what steps to take next.

Answer №1

After some research, I came across a solution. Utilizing the hexasphere plugin, I discovered that the center point of a face can be accessed through 

hexasphereObj.tiles[i].centrePoint
. This point object includes a method called project(radius, percent), which allows for obtaining the coordinates of a point based on a projection from the center of the hexasphere through the center of the face.

By moving the camera to this projected point and adjusting its look towards the center of the hexasphere, I was able to achieve the desired outcome.
