A dimensional transformation apparatus and related method for creating visual effects for use in live and prerecorded entertainment. The system engages an elastic projection screen with a three-dimensional object that corresponds to visual effects to be projected. By application of vacuum between the screen and the object, the screen is conformed in skintight relation to the features of the three dimensional object. An actuator, which includes a pneumatic piston, motivates the three-dimensional object to selectively engage and disengage the projection screen, and may be sequenced with projected animation corresponding to the three-dimensional object so as to create multi-dimensional special effects. A control mechanism, including a computer and timing system, digitally controls and sequences projection, dimensional transformation of the screen and background lighting and sound effects.
A three-dimensional surface shape is produced from input numerical data. The shape of a sheet elastic material is determined by the positions of a matrix of control rods. The position of each of the rods is determined by a computer-controlled system. Each rod is fitted with two pneumatically controlled locking mechanisms, one for the X coordinate and one for the Y coordinate. When both locks on a particular rod are released the rod is free to move to a new position determined by an elevator. Once all of the rods have been adjusted they are locked in position and the surface has been configured. In one application, the surface can be used as a mold for casting a replica or in another application can be used as the screen in an image projection system.
A process for displaying an animated likeness of the face of a character, includes the steps of (a) providing a face screen having a three-dimensional representation of the face of the character; (b) making a projectable image of the face of the character with an image recorder while projecting the image on the face screen with a projector; (c) obtaining a presentation registration of the image and the face screen through a process selected from the group consisting of (i) altering the projectable image, (ii) adjusting at least one component of face screen position, image recording means position, projector position, focal length and lighting while making the projectable image, and (iii) combinations thereof; and (d) subsequently projecting the image on the face screen at the presentation registration whereby an animated likeness of the face of the individual is presented. An apparatus for carrying out the process is also provided.
A video projection system employing a concave video screen which provides for enhanced depth cueing. A method of designing a variety of shapes of video screen surfaces by varying certain parameters of a common master equation. Video screen surface shapes providing optimum viewing for specific applications.
