Move three points in Cartesian space and measure Euclidean distance or the angle A–B–C from the same explicit three-dimensional coordinates used by the visual scene.
3D geometry
Coordinates and measurements share the same Cartesian state. Rotate, tilt, and zoom change only the view, never the measured geometry.
Measurement
90°
Angle at vertex B between vectors BA and BC.
Geometry
d = √(Δx² + Δy² + Δz²)
cos θ = (BA · BC)/(|BA||BC|)
