Abstract

A system for large scale spatial positioning of a 3D virtual object in a 3D virtual scene, includes a computing device. The computing device: displays a guide plane attached to the object, the guide plane passing through a center of the object and being translucent, the guide plane indicating lines and curves of intersection between the guide plane and other objects of the scene. When moving the object along an axis, the computing device determines a normal of the guide plane to be parallel to the axis and passing through the center of the object, and moves the guide plane with the movement of the object. When moving the object across the movement plane, the computing device determines a normal of the guide plane to be parallel to a normal of the movement plane, and holds the guide plane static.

Dependent claims

A computer-implemented method for large scale spatial positioning of a three-dimensional (3D) virtual object in a 3D virtual scene, computer-implemented method comprising:

in a first computer process implemented on a computer, attaching an object controller to the 3D virtual object, the object controller moving the 3D virtual object in the 3D virtual scene along an axis or across a movement plane in response to a user input;
and
in a second computer process implemented on the computer, displaying a guide plane attached to the 3D virtual object, the guide plane passing through a center of the 3D virtual object and being translucent, the guide plane indicating lines and curves of intersection between the guide plane and other objects of the 3D virtual scene which intersect with the guide plane, such that the guide plane demarcates portions of the 3D virtual object and the 3D virtual scene on either side of the guide plane;
wherein, when moving the 3D virtual object along the axis, determining a normal of the guide plane to be parallel to the axis and passing through the center of the 3D virtual object, and moving the guide plane with the movement of the 3D virtual object;
and
wherein, when moving the 3D object across the movement plane, determining a normal of the guide plane to be parallel to a normal of the movement plane, and holding the guide plane static.

A system for large scale spatial positioning of a three-dimensional (3D) virtual object in a 3D virtual scene, comprising:

a display device displaying the 3D virtual object in the 3D virtual scene;
an input device receiving input from a user;
a computing device in communication with the display device and the input device, the computing device:
attaching an object controller to the 3D virtual object, the object controller moving the 3D virtual object in the 3D virtual scene along an axis or across a movement plane in response to user input from the input device;
and
displaying on the display device a guide plane attached to the 3D virtual object, the guide plane passing through a center of the 3D virtual object and being translucent, the guide plane indicating lines and curves of intersection between the guide plane and other objects of the 3D virtual scene which intersect with the guide plane, such that the guide plane demarcates portions of the 3D virtual object and the 3D virtual scene on either side of the guide plane;
wherein, when moving the 3D virtual object along the axis, determining a normal of the guide plane to be parallel to the axis and passing through the center of the 3D virtual object, and moving the guide plane with the movement of the 3D virtual object;
and
wherein, when moving the 3D object across the movement plane, determining a normal of the guide plane to be parallel to a normal of the movement plane, and holding the guide plane static.
