I’ve done a lot of projects over the years, and I’m finally getting around to documenting some of them …
Walking Mechanism
A four-legged Theo Jansen “Strandbeest” walking mechanism.
Subtractive Color Mixture Computation
How to model subtractive color mixture in RGB computer graphics.
Generating Reflectance Curves from sRGB Triplets
Five algorithms for converting sRGB color values to realistic spectral reflectance curves.
Fast RGB to Spectrum Conversion for Reflectances
A new faster way to get reflectance curves from RGB values that is useful in subtractive color mixture.
Rec. 2020 RGB to Spectrum Conversion for Reflectances
Application of the spectral reflectance reconstruction methods to a wide color space called Rec. 2020.
MATLAB/Octave and Python Source Code for Reflectance Reconstruction and Chromatic Adaptation
A repository of source code, examples of how to use them, and various applications.
Vision in Curved Space
A study of how visual perception would change if we lived in a relatively small spherical universe.
Segway-Style Balancer
A low-cost, simple Segway-style self balancing device made from off-the-shelf parts.
3D Shadowlamp
A device that casts 3D shadows.
Ceramics
Work I created after retirement while being a nondegree undergraduate ‘senior’ in the College of Fine and Applied Arts at the University of Illinois, 2010-2013.
UPS Time Exposures
A project I did with my wife’s K-1 class at University Primary School, Feb 2012.
Monomial Method
A numerical method for solving nonlinear equations, and the graphical investigations leading to my Design by Algorithm work.
BLIFNAR
A device that charges in the sun all day and blinks all night.
Design by Algorithm
Jumps to my Design by Algorithm website. I exhibited math-based artwork at weekend art fairs throughout the Midwest for 25 years (1990-2015).
