It's rude to answer your own questions, but here goes anyway. Here are some ways to shear and twist prisms. To follow along, go up, copy, paste and run the regInfo[] function. The purpose is to show ways to build extrusions, skew and twist them. ... |
Without knowing anything about the graphics standards you have to work to, and steeped in the study of Tufte, my personal preference would be, FWIW: Plot[{B1@z, B2@z, B3@z, B4@z, B5@z, B6@z}, {z, -0.3, 0.3}, PlotStyle ->... |

Thanks for the reply. I evidently mistyped the command in the message above, but I can report progress. I did a full clean reformat of my SD card, loaded a fresh copy of NOOBS onto it, booted the RPI, installed Raspian, sudo apt-get update, sudo... |
Sorry about this, but I just can't get the Community editor to do anything sensible. I tried to respond to David Reiss' post, but my message text was deleted and the text of the original post was substituted. I tried to edit my message to blank it... |
