Abstract:
A computer implemented method for projecting an enlarged computer graphic image of a three-dimensional (3D) object onto a display surface using a video projector connected to said computer, wherein said computer graphic image is projected onto a concave 3D display surface having a shape corresponding to said 3D object, and wherein said computer graphic image is derived from a volume of digitally formatted data stored in a memory of said computer, said method comprising:a) storing said volume of digitally formatted data in said memory of said computer;b) creating a mathematical model for a surface having a shape corresponding to said concave 3D display surface in said memory, wherein said mathematical model at least partially intersects said volume of digital data in said memory;c) extracting data from said volume of data intersecting said mathematical model in said memory to provide an extracted data set; andd) projecting said extracted data set onto said concave 3D display surface to produce said enlarged computer graphic image of said 3D object.
