SphereGeometry with 2D Outline

It may not be that simple, because the circular outline of a sphere devolves into an ellipse-like shape when projected onto a (oblique) plane:

How to control perspective distortion of THREE.PerspectiveCamera

This is a normal and expected behaviour of how perspective projection is calculated in computer graphics. It uses a flat projection plane, instead of a curved surface. See the diagram below, an object at the left edge should appear horizontally stretched, even if it is at the same distance from the projection plane. [image] There are several ways to deal with this: use orthographic projection (at the cost of losing perspectiveness) use very narrow FOV (at the cost of reduced vision span an…
