Take the quiz
Answer the questions of a model and win its trophy.
Some models come with a quiz. It is a section of the panel, like the others: open it from the bar to start.
Answering
Questions come one after another, and the model is there while you answer: you can rotate it and zoom on it to look for the answer.
While a question is open, the quiz keeps you in its section, so you do not lose your answer by scrolling past it.
The trophy
Finish the quiz and you win its trophy.
When a quiz is updated later on, its trophy can be won again: replay it to win the up-to-date trophy.
