This was my very first computer graphic image I considered an original work of art. Both figures were initially drawn by hand, transferred to graph paper then converted to a list of coordinate pairs. Care was taken to make sure each figure had the same number of points and lifted the plotter pen in the same location.
I used linear interpolation to make the transformation between the two figures. The full images were placed a certain distance apart in the plane of the paper on both ends. The Banana was at zero, the ice cream cone was at one. If I wanted to get an in-between image, I would use the computer and a linear interpolation algorithm to compute the in-between figure based on a fraction between 0 and 1. For example a fraction of 0.5 would give me an in-between that was 50% of one figure and 50% of the other, and its location would be exactly in the middle between the two figures.
After several attempts I carefully choose the in-between fractions not leaving the transformation to chance.
I've been involved in many aspects of computer art/computer graphics. First as a student and pioneer of the medium at Michigan State University (MSU). Followed by several years of professing engineering graphics, computer graphics and computer art at The Ohio State University (OSU). Followed by being called upon to start a program at Northern Illinois University (NIU), College of Visual and Performing Arts, School of Art, Department of Design called Electronic Media, where I was an Associate Professor of Design.
This collection presents the original plotter drawings (pen on paper) programmed in FORTRAN, executed on a CDC6500 mainframe computer and an offline Calcomp 936 drum plotter. Done at Michigan State University during my MFA/PhD era, 1974-1981.
First buyer of every artwork gets an original print mailed to them. Contact me on Twitter to arrange this.
