Thanks Samual! This is all good learning practice. Cheers, Lester

Re: [Scilab-users] Coding for a 3D Klein Bottle

Hello Lester,

The code was just missing many dots (* => .*, ^ = .^), to make operators 
working in an elementwise way (see attachement).

Fixing that makes the expected picture:

This could make a nice demo, in the /Graphics => More surfaces/  section.

Regards
Samuel

Hello all,

I have been testing the latest version of Scilab (6.0.1) and have been 
looking at data visualisation of non-orientatable surfaces (e.g. 
Moebius, Klein Bottle etc.).


The Moebius strip was not hard to figure out, but I am having issues 
with the Klein Bottle.I have attched the code as is so far, uses the 
parametric equations from https://en.wikipedia.org/wiki/Klein_bottle, 
for the 3D immersion of the bottle.


As a test, I used the old software Derive 6 to run the equations and 
it plots the bottle as correct. If anyone has pointers on this code 
that would be helpful.


Still learning Scilab!

Thanks
Lester

[Scilab-users] Coding for a 3D Klein Bottle

[Lester Anderson]

Hello all,

I have been testing the latest version of Scilab (6.0.1) and have been
looking at data visualisation of non-orientatable surfaces (e.g. Moebius,
Klein Bottle etc.).

The Moebius strip was not hard to figure out, but I am having issues with
the Klein Bottle.I have attched the code as is so far, uses the parametric
equations from https://en.wikipedia.org/wiki/Klein_bottle, for the 3D
immersion of the bottle.

As a test, I used the old software Derive 6 to run the equations and it
plots the bottle as correct. If anyone has pointers on this code that would
be helpful.

Still learning Scilab!

Thanks
Lester
