Augsburg Cabinet Augmented Reality (AR) Feature
Project Description
The Augsburg Cabinet Augmented Reality (AR) feature includes a 3-D representation of the Museum's Augsburg Cabinet rendered in the web camera view with its base coincident with a detected AR marker, cabinet doors that open as the user spins the cabinet to reveal a face/side, cabinet drawers that open as the user spins the cabinet to reveal a face/side , and 2-D overlay text that displays a description of the user-facing Cabinet face. The AR experience consists of Adobe Flash .swf files along with all art assets and source code. 3-D model of the Augsburg Cabinet in Cinema 4D (C4D) format was converted into Collada format for display using Papervision3D (a Flash 3D library). The model and textures were optimized for performance, reducing polygon counts and texture sizes as necessary, while attempting not to significantly sacrifice the rendering quality of the model. Two versions of the model were created–one with all model elements opaque, and one with the structural model elements transparent. Four animations were created–one for each face of the cabinet – of the drawers of the cabinet opening outward, and four animations of the drawers of the cabinet closing again. The augmented reality marker is roughly 2.5in x 2.5in when printed, and consists of a black silhouette of the cabinet. Two versions of the augmented reality application were created. One version utilizes an opaque 3-D model, and one utilizes a transparent 3-D model. In the opaque version of the experience, the cabinet doors are animated to open and closed as described below. In the transparent version of the experience, the cabinet drawers animate open and closed as described below. In the opaque version of the experience, as the user turns the AR marker different faces of the cabinet will come into view. The doors of the cabinet on the face that is most in view will be opened proportionately to the angle between the current rotation of the cabinet and the “fully user facing” rotation. In other words, as the cabinet rotation approaches the “fully user facing” rotation point, the doors will open wider until fully open, and as the rotation angle gets further away from the “fully user facing” rotation point, the doors will close further until fully closed. In the transparent version of the experience, as the user turns the AR marker to reveal a cabinet face, the drawers of the cabinet on the face that is most in view will animate outward. The opening drawers animation will be triggered to occur as soon as the user rotates the cabinet to within a pre-determined angular range that is sufficiently user facing (e.g. “within a 45 degree arc from straight on”). The drawers will animate closed again as soon of the pre-determined angular range. In both versions of the experience, a 2-D text overlay is shown in the upper left of the AR window that provides a description of the face of the cabinet currently being viewed.
