To check if a point is inside a circle, you can use the mathematical formula that involves calculating the distance between the point and the center of the circle. If this distance is less than or equal to the radius of the circle, the point is inside the circle. This concept is often used in graphics and game development.
In the context of the WWDC sessions, the session titled "Explore game input in visionOS" discusses gestures involving circles. Specifically, it mentions checking the distance between the tips of fingers to recognize a circle-shaped gesture. This is similar to checking if a point is inside a circle, as it involves calculating distances to determine spatial relationships.
For more detailed information on creating custom gestures, you can refer to the Explore game input in visionOS session at the "Custom gestures" chapter.
