Studying a new GeometricScene command, I try

ClearAll["Global`*"];
GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, 
e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, b, d}]}]

which works well (see here). After that I execute

ClearAll["Global`*"];GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, 
e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, e, d}]}]

which returns the input instead of a picture without any communication.

What is the reason of these different results?

    $\begingroup$ Nice to see it. Works also in 13.2 on Windows 10. $\endgroup$

  • $\begingroup$ @user64494 thanks for letting me know. it's good to know that it was version dependent and not OS related! $\endgroup$

Depends on what version of Mathematica You are using.

This wrapper for graphical output is needed in mine:

ClearAll["Global`*"];
RandomInstance[
 GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, 
   e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, b, d}]}], 
 RandomSeeding -> 1]

graphics output with Randominstance and RandomSeeding

  • $\begingroup$ Thank you. Works in 13 on Windows 10. Unfortunately, I don't find any description of the RandomSeeding -> 1 option in the documentation to RandomSeeding. $\endgroup$

  • $\begingroup$ The RandomSeeding -> 2 and RandomSeeding -> 1234 and RandomSeeding -> Automatic options also work here. $\endgroup$

  • $\begingroup$ Unfortunately, this is not it: the question is about GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, e, d}]}], not about GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, b, d}]}]. The command RandomInstance[ GeometricScene[{a -> {0, 0}, b -> {1, 0}, c -> {1, 1}, d -> {0, 1}, e -> {1/2, 1}}, {Rectangle[a, c], Triangle[{a, e, d}]}], RandomSeeding -> 1] still returns the input in version 13 on Windows 10. $\endgroup$

  • $\begingroup$ RandomInstance does nothing in your code, because the GeometricScene specification already contains explicit values for all points. $\endgroup$
