I use ShaderMaterial and integrate multiple points into Three.Points, and Raycaster works well to pick single point of Three.Points. But now I need to select all points in a rectangle on the screen, which reminds me of the SelectionBox. But SelectionBox regards all points in Three.Points as one, and it works differently from Raycaster. So how can I implement the above effect, without rendering every point on my screen as a Three.Points
