Claims
- 1. A method for controlling a patch-driven video 3D special effects system which constructs an output display of a desired three-dimensional shape with real-time video picture information displayed on a surface of said shape, by dividing a video source plane into a plurality of polygonal patches and manipulating said patches in three dimensions to create said shape, said method comprising the steps of:
- A) receiving a plurality of inputs from a user defining a plurality of control parameters;
- B) dividing said source plane into a plurality of polygonal patches by means of a number of straight line segments, the number of said patches determined by a first of said control parameters, said line segments being segments of lines that emanate from a point located at a position determined by a second of said control parameters;
- C) rotating at least one of said patches around one of said straight line segments at an angle specified by at least a third one of said control parameters to construct said shape having a size, orientation and position; and
- D) manipulating said shape size, said shape orientation and said shape position in accordance with a fourth, fifth and sixth of said control parameters.
- 2. A method for controlling a patch-driven video 33 special effects system according to claim 1 wherein step A comprises the steps of:
- A1. displaying said control parameters to said user; and
- A2. adjusting the control parameters displayed in step A1 in accordance with said inputs received from said user.
- 3. A method for controlling a patch-driven video 3D special effects system according to claim 1 wherein step B comprises the steps of:
- B1. determining the number of said lines in accordance with one of said control parameters; and
- B2. determining vertices for each patch to be the points where said lines intersect the edges of said source plane.
- 4. A method for controlling a patch-driven video 3D special effects system according to claim 3 wherein step C comprises the steps of:
- C1. moving said vertices with respect to said source plane cause a rotation of said patch around said one line segment.
