THREE.js – get cartesian plane of a SphereGeometry

Issue

Im building a tile engine which wraps a SphereGeometry and im struggling with getting the 2D plane of the geometry.
I need that because further im looking to get the visible area only in order to increase network efficiency.

Any ideea is welcomed.
Thank you!

Solution

Your question needs more details to fully understand what you’re trying to achieve.

• Maybe you could look at the sphere’s UVs. They’re always mapped in 2D space in the [0, 1] range.
• Or you could use the Spherical class, which could take an x, y, z value, and it’ll return phi, theta, radius values. You could use the phi, theta as latitude & longitude. See here for documentation
