> How a Robot Hitchhiked Across Canada

Incidentally, each of the illustrations was produced as A3 size artwork, so that if I decide to get some prints that the artwork is at the right size for big enough yet budget price laser prints.

The artwork is produced using Serif Affinity Designer. The QR code is bit map and imported, everything else is vector and generated in Affinity Designer.

The buttons are each a trapezium, the red button and the green button have both had shear applied to try to produce a perspective-like picture.

The yellow triangle was drawn using the Pen Tool and the positions of the points set using the Node Tool.

Here is a graphic that is intended to give an indication of the the effect of clicking the red button eight times, with a click of the blue button between each such click of the red button. The yellow triangle has rotated about its vertical axis by 80 degrees. So the lower vertex of the triangle at the right of the picture has moved nearer the person and the lower vertex of the triangle at the left of the picture has moved further away from the person.

The image is not exact, but hopefully gives a helpful indication.

I am thinking of a button being clicked by the person moving a hand down onto the button, such that the software in the tablet device detects that. That is, a real physical hand of the person is deteted as being in the same place as the "let's pretend" augmented reality button.

So the screen should display on the tablet sshould look something like the following, showing the gallery wall, the picture with the QR code and the buttons and the triangle.

Please imagine that the tablet device has running on it a software application that can read the QR code and if the QR code contains commands that have been devised for this thought experiment then it can obey them.

These commands have the effect of superimposing on the view of the area that comes from the camera, images such as a large coloured button, like a large version of a keyboard key, or a filled yellow triangle, or a filled blue square, or an unfilled triangle where just the edges of a triangle are displayed.

A coloured button is of a preset size.

A triangle or a square is specified by a sequence of commands.

Please imagine a person going into an art gallery and now standing facing a white wall, standing about 3 metres (about 10 feet) from the wall..

On the wall there is a picture. The picture is square, each edge about 2 feet, about 60 centimetres, along each edge. The picture consists solely of a large QR code.

I have found this new website.

A good number of views of the thread yet nobody has posted about the 3d model that I have designed.

Is it that nobody is interested or does it seem too trivial to discuss or too complicated or too unclear to discuss please? Or something else, such as people being too busy to spend time discussing it?

I am hoping for a lively discussion please.

I am remembering a system that I designed in the 1990s and about which I wrote both some text and a song.

So four procedures have been added to the design, of which three are being used in the latest example.

x, y, z, MOVEPEN;

x, y, z, DRAW;

x, y, z, CLOSE;
Closes the shape directly back to the most recent MOVEPEN location.

x, y, z, FILL, COLOUR;
Closes the shape directly back to the most recent MOVEPEN location and fills with the specified colour. Only defined for a shape where all of the points are in the same plane.

Y in the FILL example is for YELLOW.

If I cut the wording down from

UNIT, METRE;
-1, -1, -0.1, BUTTON, RED;
0, -1, -0.1, BUTTON, BLUE;
1, -1, -0.1, BUTTON, GREEN;

to become

U, M;
-1, -1, -0.1, B, R;
0, -1, -0.1, B, B;
1, -1, -0.1, B, G;

that does reduce the size of the QR code.
