I need help for this picture please.

That's what I did yesterday for a similar picture.

As you can see, I used a ball insteed of the squar

What do you expect opacity=5 is going to so? The value can only be between 0 (transparent) and 1 (opaque). It can't get any more opaque than 1. Is there a reason why you start your diagrams with a white rectangle? I feel your diagrams are computer-generated. Do you want to learn from previous answers? — Qrrbrbirlbel, Aug 30 '23 at 22:30
How is the curve through B, M and C defined? What is your problem? What are you struggling with? What concept of TikZ do you not understand? How can we help you create diagrams on your own? — Qrrbrbirlbel, Aug 30 '23 at 22:33
If you really created a similar picture yesterday, what's the particular problem you're finding creating this one? — cfr, Aug 31 '23 at 02:46
@Fractal Use a rectangle instead of a circle, see also https://tex.stackexchange.com/questions/15779/materials-for-learning-tikz — samcarter_is_at_topanswers.xyz, Aug 31 '23 at 10:59

This is working.

Thank you for your helps.

Fine. However, it won‘t compile … – MS-SPO Aug 31 '23 at 13:50 — MS-SPO, Aug 31 '23 at 13:50
