Working with multiple objects, 3D artists should watch out for objects intersecting with each other — do they bounce off, overlap, or stay solid and untouched? To avoid unrealistic shape intersections — for instance, when we hold a mug, our fingers never pass through it — artists should apply collision detection techniques to ensure smooth and natural interaction. It's profoundly important for games with shooting or stabbing when accurate calculations are crucial for creating a realistic scene.^[1]
