non constant radius with CreateTube function


Recommended Posts


I want to create a tube with two kinks.  However the radius near the kinks is different to my defined radius in the CreateTube function.  I would expect a constant radius .Here is a playground example:


Furthermore, if I reduce the distance between the kinks I get a strange effect:  


I`m using BabylonJS version 2.4.

Thanks for your help

The CreateTube() function uses an algo to smoothly twist the tube according to its curves. In your case, the "curve" (or path) is really rough because it has only 4 points, what leads to really extreme twisting effects. I would suggest that you add far more points (maybe a sinus curve over an angle of PI / 2) to define something more smooth.
