Perspective puzzle

Can someone help me deconstruct how to draw this, which I assume is a circle that appears to be foreshortened or whatever and the edges start to distort. I cannot figure a way to do it.
I think that what we're seeing here is a sphere with three circles that cut it in two equal halves. The best way to approach this is to start with a cube, and then cut it in two, in three possible ways, and from there construct the circles (I will cook up an example today). Although this a good exercise, in practice most artists will simply eyeball this, and another good exercise is to tighten rubberbands around a sphere, like a tennis ball, and draw this as a model.
There we go! First, construct a cube, using basic perspective, vanishing points and everything, and use diagonals to find the middle. Then, in red, construct the square intersection, and use this to construct an ellipse, which will be the circular intersection of our sphere. Finally, fit the sphere in, and draw the visible part of the ellipse. Repeat this for the other two circular intersections. And, yes, it is labor-intensive, which is why artists typically eyeball this...
Quick drawing messy I am at work 😃 had to hurry. Basically what you need is really good perspective knowledge, to train your self to think in 3d. I would start with box like the drawing understand 2d practice ellipses then box then try sphere, hope it helps
Just a simple student but I think is just a sphere with an indicator of the 3 axis: Longitudinal (top to bot), transversal (left to right) and anteroposterior (front to back). Is like a beach ball with different colors.
Artist has to choose a point where 2 of the axis meet (long.+trans., trans+antero, or antero+long.), then draw the other one missing. In a sphere you cant meet the 3 at the same time. Maybe you can help yourself getting a polyspan sphere (they are so cheap) and putting around rubber bands, ponytail holders(?) Sorry, not native.
I hope this helped, greetings!
