Abstract:

A method, apparatus, and system provide the ability to control navigation of a three-dimensional (3D) computer aided design (CAD) model in an augmented reality space. The 3D CAD model is rendered in the augmented reality space and appears as if it is present in a physical space at true scale. A virtual camera is defined as fixed to a current pose of a user's head. A virtual line segment S is constructed coincident with a ray R from a center of projection P of the virtual camera and a center pixel of the virtual camera. A check for geometric intersections between the virtual line segment S and surfaces of scene elements is conducted. Upon intersecting with a part of the model, a gaze cursor is rendered at an intersection point C closest to the center of projection P.
