Dear forum experts,
I have to draw a Reuleaux triangle (non-obvious constant width curve) using Labview, like the one in the attached somatochart file.
The program will be used in an anthropometry laboratory to indentify the somatotype (endomorph, ectomorph or mesomorph) of individuals.
Can you give mer any suggestions?
use a XY graph and draw your curve.
What exactly is the problem?
I understand I am missing something... but the triangle is an area, not a function. The total area is 0.5(pi-sqrt(3))R^2.
R is the constant radius of the three intersecting circles.
Actually, I have no clue where to begin from...
you need to know the inner triangle. Once you know its corner points you can draw arcs (or better: calculate XY points for a plot). It looks like simple geometry math!
Now I looked at Wikipedia and I can also suggest to use a 2d picture indicator for your Releaux triangle plot. Here you could use draw functions directly instead of calculating points in a XY graph…
