GUI transform tool

Hello macro,

I am wondering if vedo is able to make a GUI transform tool like Meshmixer does (see example below), which we can use the arrows or curves to translate or rotate the object (e.g., a mesh).

Another silly question is do you know how to recover the mesh position after rotate function? I can get the original position by mesh.clone().points() before rotating, but I don’t know how to properly/easily to assign the numpy array (i.e., the output of points() function) back to the rotated mesh.

BTW, Thanks for working on vedo. It helps me finish many things in my project! It’s really amazing.

I will play with them! Many thanks!

The second T in the above example gives you the desired result. If you want to have it interactively you need to use plotter.addCallback() to have a function which is called while the window is active. E.g

from vedo import *

c1 = Cube()
c2 = c1.clone().c('violet').alpha(0.5) # copy of c1
v = vector(0.2,1,0)
p = vector(1,0,0)  # axis passes through this point
c2.rotate(90, axis=v, point=p)

def f(evt):
    if not evt.actor: return
    printc(c2.getTransform(), c=evt.actor.color())

plt = Plotter()
plt.addCallback('LeftButtonPress', f)
plt.show(c1, c2, axes=1)
