A constraint constrains one local axis of the owner to always point towards Target. This constraint uses a pure Swing rotation, i.e. the shortest possible single axis rotation. In other 3D software you can find it with the name “Look at” constraint.
Constraints are used to set up various relations between objects by
affecting their position, rotation and scale. Can be used with the
In Verge3D we use right-handed coordinate system with the Y axis pointing in the up direction, but Blender and 3ds Max uses right-handed coordinate system with Z axis pointing in the up direction (Verge3D wiki). So, to correct the rotation for cameras and lights, set fixCameraLightRotation = true. Default is false.
